Introduction
ReferenceSystems Operation

Do not perform any procedure in this Special Instruction until you read and understand this
information.

This Special Instruction explains the functionality and the features of the Caterpillar Messenger.
This Caterpillar Messenger display is adaptable on the following Caterpillar Engines. 3176B,
3176C, C-10, C11, C-12, C13, C15, C-15, C-16 and 3406E.

Note: This Caterpillar Messenger will support the 3116, 3126B, 3126E, C7, and C9 Engines.
However, it will only support these engines if they were manufactured after August 1996.

NOTICE

Select the desired display prior to moving the vehicle. Do not

manipulate the display while the vehicle is moving. This could divert
attention from driving efforts and result in personal injury or
equipment damage.

Messenger display

The Messenger display will show information for the engine and information for the vehicle. For
detailed operating information, see the Operation Section of this manual. The driver should review
the information in this manual prior to driving. Before driving, the driver should review the
Messenger Screen Map in order to select the most important information for the trip. This will
avoid the entry of data during the operation of the vehicle.

On the first pass of flashing new messenger software over an old existing version, the standard
defaults will be as follows.

• Language will be in English

• Units will be in English

• The contrast, brightness, and backlighting will all be set to the factory default

All the above settings can be changed as required by the operator. After the changes are made a
two minute wait time is required. After the two minute wait time, the messenger will have a "Key
Cycle" to enforce the changes with the messenger.

Note: A Caterpillar Electronic Technician (ET) may be used to make changes to the Messenger.
For Illustration purposes this document uses English units.

Engine Operating Information

The Messenger display provides information on cruise control set speed, PTO engine rpm set
speed, fuel temperature to the engine, boost and oil pressure, coolant temperature, and intake
manifold temperature.

Information on the Trip of the Vehicle

The Messenger display provides information concerning the quantity of fuel that has been used,
the fuel economy, the average vehicle speed, idle time, PTO time, percent idle hour, idle fuel, and
PTO fuel. These parameters may relate to trip segments or to the engine history. A Driver and a
Fleet Trip Segment is available for 3176B, 3176C, C-10, C11, C-12, C13, C15, C-15, C-16, and
3406E engines only. For the Driver Trip Segment, the driver determines the start and stop points.
For the Fleet Trip Segment, the vehicle owner determines the start and stop points. The vehicle
may be operated in separate states. The Fleet Trip Segment may be tied to each of these states.
The Fleet Trip Segment may be split between two drivers and two ID codes.

Maintenance Information
The last oil change may be entered. This allows the display to indicate when the next oil change is
due.

Diagnostic Data
Engine diagnostic codes may be displayed for the driver. The Messenger display will
automatically display potentially serious engine problems. When one of these codes appears, the
driver should bring the vehicle to a safe stop. After the display of a serious diagnostic code, the
engine may shut down within 20 seconds. Refer to the Diagnostic Code Chart for a list of these
codes.

Theft Deterrent
Messenger provides the capability to allow the engine to start or the capability to prevent the
engine from starting. The Messenger display can shut down the engine after entering a password
with four characters into the display when the engine is at idle.

Correction for the Fuel Adjustment

Messenger provides the capability to adjust the Fuel Correction Factor of the ECM.

Configuration of the Display

Messenger can provide information in either English, French, or Spanish. Units of measure can be
displayed in English (miles per hour, US gallons, psi, and °F), English (miles per hour, Imperial
gallons, psi, and °F), or Metric units (kilometer per hour, liters, kPa, and °C). The French or
Spanish manuals may be ordered by contacting a Caterpillar dealer.

Entry of the DRIVER ID

The Messenger display provides the capability to enter the ID of multiple drivers. This allows the
ECM to log information for multiple drivers. This is useful in driving applications that involve
several drivers.

State Crossing
Messenger allows the driver to enter the current state.

Access to Parameters
The availability of parameters is determined by the engine manufacturer, the model year of the
engine, and the ECM settings for the Customer Programmable Parameters.

Note: The Messenger display may be used on engines that are not manufactured by Caterpillar.
Limited instantaneous data and diagnostic data will be available for these engines. Also,
Messenger will only support 3116, 3126 HEUI, C7, and C9 engines that have been produced after
August 1996.

Screen Display Totals Information

Trip Segments
The Messenger display will provide operating data on the engine in a variety of ways. The
Messenger display provides the method in order to label information for both driver and the
vehicle owner. With the 3176B, 3176C, 3406E, C-10, C11, C-12, C13, C15, C-15, and C-16
engines, the Messenger display records information in three separate ways. Lifetime Totals, a
Fleet Trip Segment, and a Driver Trip Segment are recorded. With 3116, 3126B, 3126E, C7, and
C9 engines, the Messenger display records a Fleet Trip Segment and Lifetime Totals.

Lifetime Totals
Lifetime totals are permanently stored in the ECM on the engines. The information is recorded
throughout the life of the engine. The Lifetime Totals cannot be reset under normal operation. The
Lifetime Totals cannot be deleted under normal operation. The Lifetime Totals are shown on the
screen map for the Messenger display.

Fleet Trip Segment

This information is intended for the fleet owner or owner driver. The ability to reset the
information from the Messenger display depends on the software program. The Fleet Trip
Segment may be reset with the Cat ET and the appropriate passwords. Resetting the Fleet Trip
Segment does not affect the Driver Trip Segment or the Lifetime Totals. The Fleet Trip Segment
is shown on the Messenger screen map. The Messenger display provides the driver with the
capability to enter the current state. The information on the state is part of the Fleet Trip Segment.
The Messenger display provides the capability to enter the information for two drivers for the
Fleet Trip Segment. The Fleet Trip Segment can be sorted for the two drivers by the Messenger
software. The information on the state is shown on the screen map for the Messenger display.
Entering the State Crossing and the DRIVER ID is explained further in the manual. Resetting the
Fleet Trip Segment will clear the Driver ID for Fleet Trip. Resetting the Fleet Trip Segment will
clear the Fleet Trip State Totals.

Driver Trip Segment

The Driver Trip Segment is intended for the driver and the Driver Trip segment is controlled by
the driver. The Driver Trip Totals are shown on the screen map for the Messenger display in
column 2. Resetting the Driver Trip Segment does not affect the Fleet Trip Segment or Lifetime
Totals. Resetting the Driver Trip Segment does not affect the State Totals or the DRIVER IDS.

Example of Trip Segments and Lifetime Totals

Description

A state crossing is entered and the vehicle operation is now recorded for State 2. The
500
data for State 1 is stored.
1000 Driver 2 begins driving and the vehicle operation is now recorded for Driver 2. The
data for Driver 1 is stored.
2000 A third state crossing is entered and the vehicle operation is now recorded for State 3.
The data for State 1 and State 2 is stored.
2800 The Driver Trip Segment is reset. The Fleet and "Lifetime" information is not
affected.
3300 Driver 1 returns as the driver. New information is now added to the previous Driver 1
records. The records for Driver 2 are stored.
3800 The vehicle has re-entered State 2. Operational information is now added to the State
2 records. The information for State 1 and State 3 are still stored.
5000 The Fleet Trip is reset. This clears the records for the State and the DRIVER ID.
Driver Trip and Lifetime Totals are unaffected.

"Diagnostic Data" Screens

The display will automatically indicate certain diagnostic codes as the codes occur. The
"DIAGNOSTIC DATA" screens provide the advantage of indicating the reason that the Check
Engine lamp has come on. The codes will be displayed with the PID-FMI diagnostic code
(Parameter Identifier and Failure Mode Identifier) and a brief text description. If more than one
code is active, pressing the Down arrow button will scroll through the remaining codes. An active
diagnostic code that becomes inactive will disappear from the screen. Press the Right arrow button
in order to return to the title screen. The display will indicate other codes or "No Active Codes".

111-01 "Low Coolant Level Warning"
105-00 "High Inlet Manifold Temp Warning"
105-11 "Very High Inlet Manifold Temp"

The diagnostic codes in the " Automatically Displayed Diagnostic Codes" chart will be displayed
whenever the codes are active. The display will continue to show these codes until any button is
pressed. The display will continue to show these codes until the diagnostic goes from an active
state to an inactive state. If no other codes are active, the Messenger display will return to the
screen that was displayed before the diagnostic event.

The diagnostic codes may alert the driver to conditions that may damage engine components. The
diagnostic codes 100-11 "Very Low Oil Pressure", 111-11 "Very Low Coolant Level" and 110-11
"Very High Coolant Temperature" indicate that the engine is experiencing a serious problem.

NOTICE

Depending on the engine configuration, the engine may shut down

when a potentially serious engine problem diagnostic code becomes
active. The driver will be provided a warning before engine shutdown.

Procedure to Address the Occurrence of Codes

Whenever a diagnostic code occurs, try to note all operating conditions of the vehicle. It is
especially critical to take note of the operating conditions for intermittent codes. This information
provides the technicians with the operating conditions at the time of the intermittent code. This
will enhance the technician's ability to produce the code again. This will also enhance the
technician's ability to diagnose the problem. The codes are recorded in the ECM and the codes
may be recovered with the Cat ET.

Diagnostic Code Chart

The following "Suggested Driver Action for Diagnostic Codes" chart is provided in order to help
determine the action that should be taken if a particular diagnostic code is active. The chart is
intended as a general guideline. The current operating conditions will determine the reaction of the

driver to the codes. As an example, only intermittent service codes that are a persistent problem
should be serviced.

The "Shutdown Vehicle" code indicates the presence of a condition that could potentially damage the engine. The
driver should bring the vehilcle to a stop off the road and out of traffic.
(2)
The "Service ASAP" code indicates that the driver should go to the nearest qualified location for service if
vehicle performance is adversely affected.
(3)
The "Schedule Service" code should be addressed at the next convenient opportunity if vehicle operations is
adversely affected.

"Theft Deterrent" Screens

Theft Deterrent
The Messenger display provides the capability to allow the engine to start, the capability to
prevent the engine from starting, or the capability to shut down the engine. This may be done by
entering a customer password with four characters into the display when the engine is at idle.

In the powerup sequence, the display will indicate if the "Theft Deterrent System" is enabled,
automatically enabled, or disabled. The "Theft Deterrent System" may be enabled or the system
may be automatically enabled. The engine will not start until the customer password with four
characters is successfully entered into the display. If the system is disabled, the engine will start
without the password. To enable the system, the customer password must be successfully entered.
The passwords that are entered will not be accepted if the engine is not at idle condition. In order
to automatically enable the system, the vehicle needs to be shut off in a normal manner. The
"Theft Deterrent" parameter needs to be programmed in order to be in the "Automatically Enable"
mode.

Accessing Theft Deterrent

ECM Customer Programmable parameters determine the access to this function of the dash
display and the Theft Deterrent password. The ECM must be programmed to allow access to this
screen. The ECM must be programmed or the entire "Theft Deterrent" column of the screen map
will not be shown. Pressing the Right arrow button on the "DIAGNOSTIC DATA" title screen
will cause the display to pass over the "THEFT DETERRENT" title screen.

After the parameters are programmed in the ECM, the power must be turned OFF and the power
turned ON again in order for the display to recognize the change.

Troubleshooting
The following list may be some of the possible problems that may occur.

1. Unable To Read Characters On The Display

Probable Cause

◦ Portions of the display may not light. Part of a character is missing, etc. The unit must
be replaced.

2. The Display May Not Have Power.

Probable Cause

◦ Make sure that the On button has been pressed.

◦ Loose power or loose ground connections to the display

◦ The vehicle battery is dead.

◦ After checking the above items, if condition still exists refer to Step 1 of Diagnostic
Test.

3. No Data Link Communication

https://sisweb.cat.com/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sisw... 29/04/2013
Media Search - REHS1413 - Installation and Operation of the Caterpillar Messenge... Page 81 of 97

Probable Cause

◦ No connection or an intermittent connection in one of the two Data Link lines to the
engine ECM

◦ Connection to the J1922 Data Link or the J1939 Data Link instead of the J1708 ATA
Data Link

◦ The data link lines must be the twisted pair.

◦ The engine has no power, intermittent power, or poor ground connections to the
engine ECM. After checking the above items, if a condition still exists refer to Step 4
of the Diagnostic Test.

4. All Data Except Lifetime Totals Has Been Reset.

Probable Cause

◦ The unswitched battery connection to the engine ECM is disconnected. This is

possibly due to vehicle service or a battery disconnect switch.

◦ The data has been intentionally reset with the display, "Caterpillar Fleet Information
Software", or the Cat ET. Determine the reason for the reset and avoid the conditions
that caused this event. If a different system problem is suspected, consult a qualified
service shop.

5. The Fleet, Driver Trip Data, and Lifetime Totals Have Been Reset.

Probable Cause

◦ The engine ECM was recently replaced. Determine the reason for the reset and avoid
the conditions that caused this event. If a different system problem is suspected,
consult a qualified service shop.

6. The driver is Unable to Adjust The Fleet Trip or Unable to Reset the Maintenance.
The driver is Unable to Reset the "Fuel Correction".

Probable Cause

◦ The ECM parameters are programmed to prevent the reset of these parameters by the
customer. Cat ET and authorization from the owner will be necessary to reset the
ECM. This will allow access to these functions from the display.

◦ The power to the display was turned OFF and the power was turned ON in order for
the display to recognize the change.

7. The Driver Is Unable to Access The "Fleet Trip State Totals" and "State Crossing"
Information.

Probable Cause

◦ The ECM parameters are programmed OFF in order to prevent access to this
information. Cat ET and authorization from the owner will be necessary to reset the
ECM. This will allow access to this information.

◦ The power must be turned OFF and the power turned ON in order for the display to
recognize any changes to the ECM.

Media Search - REHS1413 - Installation and Operation of the Caterpillar Messenge... Page 82 of 97

8. Certain "Instantaneous Data" Parameters Appear to be Unavailable.

◦ This information is not available on the data link. Verify that the appropriate sensors
are installed. For example, if Ambient Air Temperature is not shown by the display,
verify that an Ambient Air Sensor is installed on the vehicle.

9. The Display Will Not Become Dim On The Circuit For The Panel Dimmer.

◦ The dimmer circuit on the vehicle is not a Pulse Width Modulated (PWM) circuit.

Installation procedure
Note: Caterpillar Messenger will fit in existing openings for CAT ID driver information
displays without any additional modifications.

1. Determine and mark the location for the Messenger display.

The measurements for the Messenger display are 112 mm (4.45 inch) wide by 53 mm (2.0
inch) high. The display is 56 mm (2.3 inch) deep. The dash must be 2 mm (0.08 inch) thick
at a minimum. The dash panel may only be 6 mm (0.25 inch) thick at a maximum. This will
allow the brackets to be secured to the back of the Messenger display.

Note: If the dash is more than 6 mm (0.25 inch) thick, the brackets may be carefully
trimmed.

2. Disconnect vehicle batteries.

3. Locate all the wiring connections. The Messenger display requires a fused key switch for
the +battery, battery ground, "+ATA Data Link", and "-ATA Data Link" for proper
operation. The display may be wired to the panel dimmer switch. This connection allows the
display to be dimmed automatically with the dash panel lights. The display requires less
than 500 mA of power.

a. The key switched power to the +battery and the battery ground should be available in
the fuse panel of the cab.

b. The "+ATA Data Link" and "-ATA Data Link" may be located behind the dash data
link. A two-pin connector for the data link connection may be supplied by the vehicle
manufacturer. Do not confuse the lines for the J1708 ATA Data Link with the lines
for the J1922 or the J1939 Data Link.

c. The connection for the panel dimmer switch should be accessible from behind the
dash. The circuit for the panel dimmer switch must be a Pulse Width Modulated

https://sisweb.cat.com/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sisw... 29/04/2013

(PWM) circuit. Contact the vehicle manufacturer in order to determine the type of
circuit for the panel dimmer or refer to the wiring schematic of the vehicle. The data
link for the +battery and the battery ground have connections for the display. The
connection for the +battery may be unswitched. Do not connect the display to
unswitched power. Connect the Messenger display to the key switched battery
connection for the +battery and the battery ground.

4. Connect the key switched battery connection to the +battery and the battery ground. Crimp
a terminal from the display connector (+battery) (pin 1) to the key switched battery

(pin 3) and battery ground (pin 4) with the key switch in the On position. The voltage
should be 11 to 13.5 volts DC.

b. Turn the key switch to the Off position and measure the voltage again. The voltage
should be 0 volts when the key switch is in the Off position.

Note: The supply voltage to the Messenger display may be from 9 volts to 32 volts
DC.

6. Connect the data link lines.

Note: The data link lines must be connected correctly or the display will not work. The
data link lines must be the twisted pair.

a. Temporarily connect the display to the wiring harness.

b. Turn the key switch to the On position. The display should come on.

c. Verify that the display comes on. If there is no communication, turn the key switch to
the Off position. Switch the data link lines.

d. If this does not solve the problem, either the connections are not sufficient or the lines
are connected to the wrong data link connector. The connection is to the J1922 Data
Link or to the J1939 Data Link instead of the J1708 ATA Data Link.

e. Remove the dash panel and cut the opening to the proper size for the display.
Determine the location for the Messenger display in the dash panel. Verify that the
location that is chosen is adequate for the installation of the Messenger display.
Carefully cut a 113 mm (4.45 inch) by 53 mm (2.0 inch) opening in the dash panel at
the appropriate location.

Note: Do not make the hole for the Messenger display too large. Use a file or other
means to avoid a hole that is oversize. The body of the Messenger display should fit
snugly into the hole in the dash panel.

7. Insert the Messenger display into the dash.

a. Insert the display into the cutout in the front of the dash.

b. Install the rear brackets and loosely tighten the four screws that hold the brackets in
place.

c. Ensure that the face of the Messenger display is straight and positioned correctly in
the opening.

d. Fully tighten the four screws that hold the brackets in place.

8. Secure the Messenger display wiring with tie straps in order to avoid wiring abrasion and
interference with the driver.

Note: Do not locate the wiring harness for the Messenger display near any radio wiring.
