Inspection and Verification

CAUTIONS:

Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee
confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.

1. Verify the customer concern

2. Visually inspect for obvious signs of damage and system integrity

Visual Inspection

Loose or corroded connections
Routing of fibre optic harnesses
Correct engagement of optical connectors
Correct placement of optical connectors (ring order)
Correct assembly of optical connectors (backout, etc)

Controller Area Network (CAN)

Control Module Connections to the CAN Harness

Control modules are connected to the CAN harness either in a 'loop' or 'spur' configuration. In the 'loop' type configuration the
CAN harness loops into the module (via two connector pins) and then loops out of the module (via another two connector
pins). In the 'spur' type configuration, a harness spur is spliced into the main 'backbone' of the CAN harness and the module is
connected to the harness spur via two connector pins.
CAN Harness Architecture

For a detailed description of the CAN Networks and architecture, refer to the relevant Description and Operation section in the
Workshop Manual.

CAN Network Integrity Tests

If a control module is suspected of non-communication, the Network Integrity test application available on the manufacturer
approved diagnostic system can be used to confirm if communication is possible between the control modules on the vehicle
and the manufacturer approved diagnostic system (via the J1962 diagnostic connector ). The results from the test can be used
to determine if either a single module or multiple modules are failing to communicate.

CAN Terminating Modules

If the Network Integrity test indicates that one or more module on one of the CAN networks (HS or MS) are failing to
communicate, there are several checks that can be made. The first step is to identify if both of the CAN terminating modules
on each individual CAN Bus are communicating. If both CAN terminating modules for each individual CAN Bus are
communicating (identified via the Network Integrity test), then it can be confirmed that the main 'backbone' of the CAN
harness is complete. The main 'backbone' of the CAN harness consists of all the modules connected to the CAN harness via a
'loop' configuration and also includes the two terminating modules.

Communication with both CAN terminating modules via the Network Integrity test confirms the physical integrity of the main
'backbone' of the CAN harness (and the harness spur to the J1962 diagnostic connector). This means that there is no
requirement to check the resistance of the CAN Network. This is because the standard check for 60 ohms across the CAN High
and CAN Low lines will not provide any additional information regarding the physical condition of the CAN harness, beyond
what has already been determined from the Network Integrity test.

Non-Communication of a Terminating Module

If a Network Integrity test reveals a terminating module is failing to communicate it can indicate a break in the main
'backbone' of the CAN harness. The first checks should always be to confirm the power and ground supplies to the
non-communicating module are correct. Providing these are correct, the resistance between the CAN High and CAN Low lines at
the J1962 connector can be checked to determine the integrity of the main 'backbone' of the CAN harness. After disconnecting
the battery a reading of 120 ohms would indicate an open circuit in the main 'backbone' of the CAN harness. Alternatively, a
reading of 60 ohms would indicate that there is no open circuit fault with the main 'backbone' of the CAN harness.

It is worth noting that even if one of the terminating modules is disconnected from the CAN harness, communications between
the modules still connected may still be possible. Therefore communication between the manufacturer approved diagnostic
system and the connected modules may also be possible.

cat.a.logs
Locating CAN Harness Open Circuits

In the case where multiple modules, including a terminating module, are failing to communicate, having first confirmed the
power and ground supplies are correct, the approximate location of the open circuit can be identified from analysis of the
Network Integrity test results and reference to the relevant CAN network circuit diagrams. For example, if an open circuit
existed in a certain position on the CAN harness, any module positioned on the Network between the J1962 connector and the
open circuit should return a response during the Network Integrity test. No responses would be returned from any modules
past the open circuit fault in the Network.

CAN Harness 'Spur' Type Configuration Circuits

If, after the initial checks (Network Integrity test using the manufacturer approved diagnostic system, and power and ground
supplies to the module have been checked and confirmed as correct), a module that is connected to the CAN harness via a
'spur' type configuration is suspected of not communicating, then the physical integrity of the CAN harness 'spur' can be
checked.

This is most easily undertaken by individually checking the continuity of the CAN High and CAN Low lines between the
non-communicating module connector (with the module disconnected) and the J1962 diagnostic connector.

'Lost Communications' DTCs

As well as the methods described so far in this document, which can be used to determine the location of an open circuit in
the CAN harness, 'Lost Communications' DTCs can also be used for this purpose. Lost communication DTCs mean that a
module is not receiving CAN information from another module.

For example, if a global DTC read were to be carried out, only DTCs stored in the modules that the manufacturer approved
diagnostic system could communicate with would be displayed. If there was an open circuit fault in a certain position on the
CAN harness, the modules that could display DTCs would all be prior to the open circuit on the Network, and these modules
should display 'Lost Communications' DTCs with all the modules located on the Network past the open circuit fault.

'Bus off' DTCs

The references to bus and its condition refer to the network concerned and the modules on that network.

If a module logs a 'Bus Off' DTC, it means that the module has detected CAN transmission errors and has disabled it's own
CAN transmissions and disconnected itself from the network in an attempt to allow the rest of the network to function. At this
point the 'Bus Off' DTC is set. A common cause of 'Bus Off' DTCs can be a short circuit in the CAN network.

Overview

The basic guidelines are covered in the description and operation section, such as not attempting to repair fibre optic cables,
but additional precautions include:

Do not touch the exposed ends of the optical fibres (grease from skin can contaminate the fibre)
 Whenever the fibre optic cable is disconnected, cover the connectors to prevent dust contamination
Do not expose the fibre optic cable to heat
Do not bend the fibre optic cable through less than a 25 mm (one inch) radius
Do not use laser pens to test the fibre optic cable's ability to pass light

MOST Diagnostic Tools

There are two dedicated tools for testing the MOST system:

MOST tester. The MOST tester is connected to the MOST network in place of a control module. It will confirm receipt of any

cat.a.logs
existing MOST signal and transmit it to the next control module on the network. Perform the following tests to validate the
operation of the MOST tester. GO to Pinpoint Test A.

MOST prism. The MOST prism is connected in the same way as the MOST tester but will simply reflect any existing signal
onward to the next control module. Using the MOST prism before or after a long run of harness may cause a ring break as a
good signal may be too weak after travelling the extended distance. Also, the MOST prism will pass light in either direction so
will not detect reversed MOST terminals elsewhere in the network. For these reasons, the MOST tester is the preferred tool and
should be used unless limited access does not permit it

MOST Ring Break Indication

A ring break in the MOST network is indicated by a blank touch screen display if the break is before the touch screen display or
a flashing logo of the break is after the touch screen display. Possible causes of ring breaks are listed in the symptom chart

Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)

When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account

Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

Inspect connectors for signs of water ingress, and pins for damage and/or corrosion

If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent
concern may be the cause. Always check for loose connections and corroded terminals

Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system

CAUTIONS:

Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee
confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle

When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number
3548-1358-00

NOTES:

If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component

Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)

When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account

cat.a.logs
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

Inspect connectors for signs of water ingress, and pins for damage and/or corrosion

If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent
concern may be the cause. Always check for loose connections and corroded terminals

Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system

Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required

Wiring Harnesses - Wiring Harness
Description and Operation

Introduction

CAUTION: Do not use any other heat shrink sleeve other than the approved glue lined heat shrink sleeve mentioned in
the repair procedure.

The purpose of this document is to promote quick and efficient minor repair to harness connectors or cables using approved
methods. Repairs may only be made to cables and connectors which have been mechanically, not electrically damaged. It also
applies where the whole extent of the damage can be clearly identified and rectified.

Care and neatness are essential requirements in making a perfect repair.

Caution:

This harness repair guide, does not approve repairs to any of the following circuits:

1. Any media orientated system transport network harnesses.

2. Supplement restraint system (SRS) firing circuits (Air bags).
3. Link lead assembles, which are unique to safety critical circuits such as anti-lock brake system (ABS) and thermocouple
circuits. An example of this is the ABS wheel speed sensors with moulded connectors.
4. 4. Screened cables, leads and wiring harness(s).

If any harness(s) with defective electrical connector terminals or wires from the above circuits are a concern, new
components must be installed.

Repair Components

CAUTION: Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient

cat.a.logs
heat to the glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not over heat the glue lined heat
shrink sleeve so that the wiring harness insulation becomes damaged.

The wiring harness repair components comprises:

Pre-terminated wiring harness(s) of different sizes and types

Three sizes of butt splice connectors
A selection of colored cable identification sleeves
Two sizes of glue lined heat shrink sleeves

A suitable heat source, for shrinking heat shrink sleeves will be required.

The pre-insulated diamond grip range of electrical connector terminals and in-line, butt splice connectors are the only
acceptable product for the repairs of wiring harnesses. The butt connectors not only grip the wire but also the insulation,
making a very secure joint.

If an electrical connector terminal is not available approval for the repair is NOT given and in these circumstances a new wiring
harness must be installed.

Pre-Terminated Wiring Harness(s) and Butt Splice Connectors

The pre-terminated wiring harness(s) are supplied with the insulation in one of three colors, red, blue or yellow. The colors do
not apply to any particular circuit but to the harness wire size. See the Relationship Table in the Repair Method section.

Butt splice connectors are also supplied with red, blue or yellow coverings, which must be matched to the pre-terminated
wiring harness insulation color.
 Pre-Terminated Wiring Harness(s)

cat.a.logs

The illustration shows:

The pre-terminated wiring harness(s) which are available via Jaguar/Land Rover authorised parts.
The part number of the pre-terminated wiring harness
The letter showing the extractor tip which must be used to remove this type of electrical connector terminal
Those electrical connector terminals which are gold

Some of the pre-terminated wiring harness(s) have seals installed to the insulation for sealed connector applications. It is
essential for prevention of moisture ingress that a sealed pre-terminated wiring harness must be used where a sealed terminal
was removed.

CAUTION: Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient
heat to the glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not over heat the glue lined heat
shrink sleeve so that the wiring harness insulation becomes damaged.

Two sizes of heat shrink sleeving are available. Each heat shrink sleeve contains a sealant glue. These must be used when
connecting wiring harness(s) or electrical connector terminal(s) at all times. The smaller diameter heat shrink sleeve is to be
used with the red and blue butt splice connectors and the larger diameter sleeve with the yellow butt splice connectors.

For ease and speed, some of the pre-terminated wiring harness(s) may already have the insulation partly stripped at the splice
end. If the repair requires insulation to be stripped from the cable, refer to the Relationship Table for the correct length of
insulation to be stripped.

The Pre-Terminated Wiring Harness(s) illustration shows the electrical connector terminal type, the part number of the
pre-terminated wiring harness and the letter of the extractor tip which must be used to extract the electrical connector
terminal from the connector housing. Additionally, those electrical connector terminal(s) which are gold are identified, all
others are therefore, tinned and not gold.

Wiring Harness Cable Identification Sleeves

A selection of colored sleeves are available for maintaining the wiring harness cable identification on the pre-terminated wiring
harness. Place the correct colored sleeve(s) over the pre-terminated wiring harness insulation as near to the electrical
connector as possible with the main wiring harness cable color nearest to the electrical connector.

For example, if the original wiring harness cable color is pink with a black trace put the pink wiring harness cable identification
sleeve on the pre-terminated wiring harness first followed by a black sleeve, and slide both along the wiring harness cable to
the electrical connector terminal.

Repair Tools
The wiring harness repair tools comprises:

Crimping pliers
A wire cutter and insulation stripper
An electrical connector terminal extraction handle and tips

Extraction Handle and Tips

The extraction handle, in conjunction with the correct tip, is used to remove a terminal from an electrical connector. Each tip is
marked with an identification letter, A to K inclusive. Each tip has been specially designed to extract a particular type of
electrical connector terminal. The use of any other tool is not recommended and is liable to cause damage to the electrical
connector. The tip is fastened to the handle by a screw which holds the tip firmly yet allows it to be easily replaced.
Extraction Handle and Tips

cat.a.logs
Insulation Stripper

The moving jaw has an adjuster wheel which has a series of holes in it. Turning the wheel and placing the cable in the
matching size hole will automatically adjust the jaw to the correct pressure. Note that some wiring harness(s) may have a
harder insulation and slight adjustment of the wheel may be needed to make a clean strip but exercise care not to damage the
wire.
 Insulation Stripper

cat.a.logs
By pressing the outer edges of the wiring harness cable length stop together the adjuster can be slid up or down the jaw. This
decreases or increases the length by which the wiring harness cable insulation will be stripped from the pre-terminated wiring
harness or wiring harness wire. The adjuster has a position indicator to align with a graduated scale and this sets the correct
length in millimetres, of insulation to be stripped. The amount of insulation to be stripped is shown in the Relationship Table.

The illustration shows the insulation stripper tool and a wiring harness correctly gripped in the jaws. A wire cutter is provided
on the outer side of the fixed jaw.

Cable Correctly Gripped in Stripper Blades

Crimping Pliers

Crimping Pliers

cat.a.logs
The crimping pliers have a moving jaw and a stationary jaw, with three different sized crimping enclosures. Each of the
enclosures is identified by a red, blue or yellow coloured dot which corresponds to the three colours of the pre-terminated
wiring harness(s) and butt splice connector colors.

Repair Methods

CAUTION: Several different types and sizes of terminal may be found in a single electrical connector housing.

It is necessary to identify:

The conductor (wire) size of the affected wiring harness

The electrical connector range from which the damaged wiring harness is to be removed
The terminal type

Use of the approved diagnostic tool will greatly assist in the quick identification of electrical connectors and faulty pin
terminal(s).

Reference can also be made to the vehicle Electrical Guides, held by Dealers, to identify wiring harness(s) and electrical
connector(s).

By using the Relationship Table, the wiring harness conductor (wire) size can be related to a suitable pre-terminated wiring
harness by the color of the insulation. Also, the correct length of insulation to be stripped from the wiring harness lead is
identified.

Electrical Connector Terminal Extraction

It must be noted that some electrical connector(s) have anti-backout devices which prevent the terminals from being removed

cat.a.logs
from the electrical connector. Some examples of these are shown in following illustrations. The anti-backout device must be
released before attempting to remove the terminal from the electrical connector. Some anti-backout devices require a special
tip to release the device. Most can be released by carefully using a suitable small screwdriver.

Various types of electrical connector have seals installed internally or externally to prevent moisture ingress. These normally
do not have to be removed but make sure that they are installed when the electrical connectors are connected.

The illustrations show examples of each tip used on different types of electrical connector(s). There are a large number of
different types of electrical connector used on vehicles therefore only one example using each tip is shown. Technicians
experience and judgement will dictate which type of tip should be used for those electrical connector(s) which are not shown.
Care should be exercised to avoid further damage when removing the terminals from the electrical connector.

NOTE: Examples of the extraction tips and anti-backout tips.

Repair Procedure
CAUTIONS:

Do not use crimping pliers, insulation strippers, butt splice connectors, heat shrink sleeves or pre-terminated wiring
harness(s) that are not supplied with by authourised Jaguar/Land Rover parts. Each part has been designed to be used only
with the other parts available from Jaguar/Land Rover parts.

Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient heat to the
glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not over heat the glue lined heat shrink
sleeve so that the wiring harness insulation becomes damaged.

It is not correct to make more than five repair joints on the wiring harness to any electrical connector and if more damage is
found at the same electrical connector then a new wiring harness must be installed.

1. Remove the faulty terminal from the electrical connector using the extractor tool and correct tip. Make sure that any
anti-backout device is released before trying to remove the terminal.

2. CAUTION: A number of electrical connector terminals are gold plated or gold flashed. When defective, they must
be installed with a gold pre-terminated wiring harness(s). It is not always easy to identify the female as gold but the
male pins are visually easier, therefore always check both male and female terminals to identify those which are gold.
Under no circumstances are gold and tin terminals to be mixed as this will lead to early failure of the electrical contact.

NOTE: Never use a harness lead with a smaller diameter than the original harness lead.

Select the correct size and type of pre-terminated wiring harness and butt splice connector.
3. Using the wire cutter on the stripping tool, cut the pre-terminated wiring harness and the harness cable to the required
 length.

4. NOTE: See illustration: Stripping Insulation

From the Relationship Table, find the correct length of insulation to be stripped from the pre-terminated wiring harness
and set the adjustable cable length stop to the correct length. Place the pre-terminated wiring harness in the wire
stripper and remove the insulation.
5. Put the cable identification sleeve(s) on to the wiring harness with the main cable colour nearest to the terminal.
6. During this next step do not over tighten. Place the selected butt splice connector in the crimping tool, matching the
aperture and the butt connector colours. Make sure that the window indentation in the butt connector is resting over
the guide bar on the lower jaw. Partially close the grip until the butt connector is securely held in the aperture. This will
give support to the butt connector while the pre-terminated wiring harness is inserted into it.

7. NOTE: See illustration: Splice Correctly Located

Insert the pre-terminated wiring harness into the butt connector and make sure that the wire is against the wire stop.
Close the grip firmly, crimping the lead to the butt connector. When the handles have been completely closed the butt
connector will be freed from the tool as the handles are released. If the handles have not been completely closed then
the jaws will hold the butt connector and it cannot be removed from the tool until the crimp is fully made by closing the
handles completely.
8. Make sure that the harness cable has been squarely cut and the correct length of insulation removed. If more than one
splice is needed the butt connectors must be not be crimped to the wiring harness at the same distance from the
connector. The splices must be staggered to prevent a bulk of splices in the same area of the wiring harness.
9. It is preferable to cover the butt splice joint with heat shrink sleeve. This is desirable not essential, except where the
electrical connector is a sealed electrical connector. Use the smaller diameter sleeve for red and blue pre-terminated
wiring harness(s) and the large diameter sleeve for the yellow pre-terminated wiring harness(s). It is advisable to place
the heat shrink over the completed joint but in some instances the sleeve will not pass over the terminal. Check, and if
required, place the correct size sleeve onto the harness cable or pre-terminated wiring harness before crimping the butt
splice to the wiring harness.
10. Place the harness cable into the butt splice with the splice window over the guide bar. Make sure that the cable harness
wire is against the stop in the butt splice, crimp the butt splice connector to the wiring harness.
11. Gently pull the harness cables each side of the butt splice to make sure that a secure joint has been made.

12. WARNING: Do not use a naked flame in areas where fuel or oil have been spilt. Clean the area of residual oil and
fuel and wait until the fuel spill has fully evaporated.

CAUTIONS:

When using a heat source make sure that it is localised and causes no damage to surrounding materials.

Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient heat
to the glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not over heat the glue lined
heat shrink sleeve so that the wiring harness insulation becomes damaged.

Using a suitable heat source, shrink the sleeve over the butt splice.
13. If further pre-terminated wiring harness(s) are to be installed to the same electrical connector, make sure that the lead
is cut at a different length to the previous joint. This makes sure that the splices will, where possible, be staggered on
the wiring harness and prevent a bulk of splices in one area.
14. When all of the splices have been made, fit the terminal(s) to the electrical connector, taking care that the terminals
are correctly orientated.
15. Install the wiring harness cover and secure with adhesive electrical tape. Do not cover the wiring harness right to the
electrical connector as the terminals must have a little movement and not be firmly bound to the electrical connector or
wiring harness. Make sure that the cable identification sleeve(s) are showing at the wiring harness electrical connector.
