Fault finding - Introduction 38C
Faults
Faults are declared to be either present or stored (depending on whether they appeared in a certain situation and
have disappeared since, or whether they remain but are not diagnosed within the current context).
The present or stored state of faults should be taken into consideration when the diagnostic tool is switched on
after the + after ignition feed (without acting on the system components).
For a present fault, apply the method described in the Interpretation of faults section.
For a stored fault, note the faults displayed and refer to the instructions section.
If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the
fault.
Conformity check
The conformity check is designed to check the states and parameters which do not display any faults on the
diagnostic tool when inconsistent. This phase therefore permits:
– diagnosis of faults that do not have a fault display, and which may correspond to a customer complaint.
– verification that the system is operating correctly and that there is no risk of a fault reappearing after repairs.
This section gives the fault finding procedures for states and parameters and the conditions for checking them.
If a state is not behaving normally or a parameter is outside permitted tolerance values, you should consult the
corresponding fault finding page.
If the diagnostic tool check is correct, but the customer complaint persists, it should be dealt with according to the
customer complaint.
A synopsis of the general procedure to follow is provided on the following page in the
form of a flow chart.

4. FAULT FINDING PROCEDURE (continued)
Wiring check:
Visual inspection:
Look for damage under the bonnet and in the passenger compartment.
Meticulously inspect the fuses, insulation and wiring routing.
Look for signs of oxidation.
Tactile inspection:
While handling the wiring, use the diagnostic tool to detect any change in the status of faults from "stored" to "present".
Make sure that the connectors are firmly locked,
Apply light pressure to the connectors,
Twist the bundle.
If there is a change in status, try to locate the source of the fault.
Resistance check:
Check the continuity of the entire lines, then section by section.
Look for a short circuit to earth at + 12 V or to another wire.

5. FAULT FINDING LOG
WARNING
All problems involving a complex system call for thorough diagnostics with the appropriate tools.
The FAULT FINDING LOG, which should be completed during the fault finding procedure,
ensures a record is kept of the procedure carried out. It is an essential item when discussing the
WARNING! fault with the manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING SHEET EACH TIME FAULT FINDING
IS DONE.
6. SAFETY INSTRUCTIONS
All work on components requires safety rules to be followed to prevent damage or injury:
– Make sure that the battery is properly charged to avoid damaging the computers with a low charge.
– Use the proper tools.
– It is forbidden to carry out a road test while dialogue is still established between the diagnostic tool and
the computer, as the ABS and Electric Braking Distribution (EBD) functions are deactivated. Braking
pressure is identical on both axles of the vehicle (risk of spinning under heavy braking).

PRESENT
The TEVES MK60 ABS / ESP computer with the tachometry function supplies the vehicle speed signal to all
areas where this information is needed (instrument panel, engine management computer, etc.).
This vehicle speed signal replaces the one supplied by the speed sensor located on the gearbox.
The ABS / ESP (electronic stability program) computer calculates the vehicle speed on the basis of the wheel
speed and circumference of the tyres fitted to the vehicle.
The tyre circumference must be programmed into the memory of a new computer. This consists of
entering an X index using command VP007 Tachometric index on the diagnostic tool.
Once the index has been entered using the VP007 command, clear the computer memory and then switch off
the ignition. Use the PR030 parameter to check that the index has been entered correctly.

REPLACING THE COMPUTER:
The TEVES MK60 ABS/ESP computer with the tachometry function transmits the vehicle speed signal to all
areas where this signal is needed (instrument panel, engine management, etc).
This vehicle speed signal replaces the one supplied by the speed sensor located on the gearbox.
The ABS/ESP computer calculates the vehicle speed from the wheel speed and the tyre circumference.
The tyre circumference must be programmed into the memory of a new computer. This consists of
entering an index "X", using the VP007 "Tachometric Index" control on the fault finding tool.
Once the index has been entered using the VP007 command, clear the computer memory and then switch off
the ignition. Use the PR030 parameter to check that the index has been entered correctly.

FAULT
FINDING No dialogue with the ABS computer
CHART 1
NOTES None
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty.
If the tool is not causing the fault and dialogue cannot be established with any other computer on the same
vehicle, it may be that a faulty computer is disrupting the K diagnostic line.
Disconnect the computers one at a time to locate the fault.
Check the voltage of the battery and carry out the operations necessary to obtain a voltage which is to
specification
(9.5 V < battery voltage < 17.5 V).
Check the presence and condition of the ABS fuses on the passenger compartment fuse board (5 A) and both
fuses in the engine compartment (30 A and 40 A).
Check that the computer connector is properly connected and check the condition of its wiring.
Check the ABS earths (good quality, not oxidised, sheath sealing ring (on the earth terminal), tightness of the
earth bolt located above the ABS assembly).
Check that the power supply to the computer is correct:
– Earth on tracks 16 and 47 of the 47-track connector.
– + before ignition on tracks 1 and 32 of the 47-track connector.
– + after ignition on track 4 of the 47-track connector.
Contact your Techline if dialogue has still not been established after these various checks.

FAULT
FINDING Locking of one or more wheels
CHART 2
NOTES Only consult this customer complaint after a complete check using the diagnostic tool.
Reminder: Wheel locking on a vehicle equipped with ABS or tyre grating, considered by the customer as
locking, can be associated with the normal reaction of the system and should not be automatically considered
a fault:
– Locking is allowed below 4 mph (6 km/h) (the system will not provide regulation).
– Braking with ABS on very poor roads (significant squealing).
However, if the wheels are actually locking, lift the vehicle in order to be able to turn the wheels and check:
– Possible reversal of the speed sensor connection.
Using parameters PR001, PR002, PR003 and PR004, turn the relevant wheels slowly and check the
consistency of the results obtained.
If the value measured is zero, turn the other wheels to confirm an electrical reversal of the sensors and repair
the wiring.
AFTER REPAIR Carry out a road test followed by a test using the diagnostic tool.

pressure
CHART 5
Only consult this customer complaint after a complete check using the diagnostic tool.
NOTES Warning: ABS regulation may be unresponsive when car is driven on surfaces such as
icy roads, cobbled streets, etc.
It is possible to feel brake pedal vibrations which are linked to the reaction of the system in particular
circumstances, such as:
– Crossing rumble strips.
– Tight cornering with lifting of the inside rear wheel.
These vibrations may be linked to the activation of the brake limiter when pressure on the rear axle is limited.
If the problem is different, check the speed sensor connectors (micro-breaks) as well as the targets.
AFTER REPAIR Carry out a road test followed by a test using the diagnostic tool.

FINDING Unexpected ABS operation on a poor road surface
CHART 6
NOTES Only consult this customer complaint after a complete check using the diagnostic tool.
On poor road surfaces it is normal to feel jolting and vibration of the pedal as well as more significant tyre noise
than on good surfaces.
This gives the impression of a variation in efficiency, but this should be considered normal.
