J1939 Code and Description Comments
29-3
Accelerator Pedal Position #2 : Voltage Above Normal The Electronic Control Module (ECM) has detected that the analog "0-5 Volt" desired speed signal has exceeded the 4.5 volt trip point.
The setting for the upper diagnostic limit has been exceeded for .6 seconds.
The code is logged.
29-4
Accelerator Pedal Position #2 : Voltage Below Normal The ECM has detected that the analog "0-5 Volt" desired speed signal is below the .5 volt trip point.
The setting for the lower diagnostic limit has been exceeded for .6 seconds.
The code is logged.
91-3
Accelerator Pedal Position #1 : Voltage Above Normal The ECM has detected that the "PWM" desired speed signal is above the 95% diagnostic limit.
The code is logged.
The alarm output is activated.
91-4
Accelerator Pedal Position #1 : Voltage Below Normal The ECM has detected that the "PWM" desired speed signal is below the 5% diagnostic limit.
The code is logged.
The alarm output is activated.
91-8
Accelerator Pedal Position #1 : Abnormal Frequency, Pulse Width, or Period The ECM has detected an erratic signal for the "PWM" desired speed signal.
The code is logged.
The alarm output is activated.
974-5
Remote Accelerator Pedal Position : Current Below Normal The ECM has detected a low current in the circuit for the "4-20 mA" desired speed signal.
The current is less than 2 mA for more than 5 seconds.
The code is logged.
The alarm output is activated.
974-6
Remote Accelerator Pedal Position : Current Above Normal The ECM has detected an excessive current in the circuit for the "4-20 mA" desired speed signal.
The current has exceeded 22 mA for more than 5 seconds.
The code is logged.
The alarm output is activated. For this troubleshooting procedure, the "Desired Speed Input" configuration parameter can be set to "4 - 20 mA" input, "PWM" input, or "0-5 Volt"input.The engine ECM will only monitor the status of the input signal for the PWM and 0-5 Volt desired speed inputs.The engine ECM does not supply the power and ground for the PWM or 0-5 Volt speed control circuits.If using the EMCP 4.3 and either the 0-5 Volt analog output or the PWM speed control feature, then the EMCP 4.3 will monitor the status of those outputs in relation to power and ground circuit health.If an external speed control source device is used, refer to that devices troubleshooting procedure.If using the EMCP 4.3 CAN desired speed input, refer to Troubleshooting, "Data Link - Test".The value of the current, frequency, or voltage corresponds to a range of desired engine speeds between minimum high idle and maximum high idle. The "Minimum Engine High Idle Speed" and the "Maximum Engine High Idle Speed" are set with the "Service/Configuration" screen of Cat ET. For more information, refer to Troubleshooting, "Configuration Parameters".The most likely causes of a diagnostic code for this circuit are a poor connection or a problem in a wiring harness. The next likely cause is a problem with a component. The least likely cause is a problem with the ECM.

Troubleshooting Test Steps Values Results
1. Inspect the Electrical Connectors and the Wiring
A. Turn the main disconnect switch to the OFF position.
B. Thoroughly inspect the connectors. Refer to Troubleshooting, "Electrical Connectors-Inspect" for additional information.
C. Perform a 45 N (10 lb) pull test on the connector wires.
D. Check the harness for abrasions and pinch points.
Connectors and Wiring
Result: The connectors and wiring appear to be OK.
Proceed to Test Step 2.
Result: There is a problem with the connectors and/or wiring.
Repair: Repair or replace the connectors or wiring. Ensure that all the seals are properly in place and ensure that the connectors are coupled.
If the problem is not resolved, proceed to Test Step 2.
2. Check for Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector.
B. Determine if a code is active or logged.
Codes
Result: Any of the following codes are active or logged:
- 29-4
- 91-4
- 91-8
Proceed to Test Step 3.
Result: Any of the following codes are active or logged:
- 29-3
- 91-3
- 974-6
Proceed to Test Step 7.
Result: A 974–5 code is active or logged:
Proceed to Test Step 9.
3. Check the Wiring for an Open Circuit
A. Ensure that the engine control is in the OFF/RESET position. Ensure that the electrical power is removed from the engine and the speed control device.
B. Remove the signal wire at the Engine Interface Connector (EIC), that carries the (PWM or analog 0-5 Volt) desired speed input signal to the engine ECM.
C. Perform one of the following:
- For the 91-4 and 91-8 disconnect the A-C1 connector from the ECM.
- For the 29-4 diagnostic disconnect the A-C2 connector from the ECM.
D. Measure the resistance between the following terminals at the removed ECM connector:
- For the 91-4 and 91-8 codes, terminal 66 of the A-C1 ECM connector and terminal 66 of the A-C9 connector.
- For the 29-4 code, terminal 94 of the A-C2 ECM connector and terminal 15 of the A-C9 connector.
Open Circuit
Result: The resistance measured less than 10 ohms.
Proceed to Test Step 4.
Result: The resistance measured more than 10 ohms.
Repair: An open circuit has been detected. Repair or replace the wiring harness.
4. Check the Wiring for a Short Circuit to Engine Ground
A. Measure the resistance between the ground strap for the ECM and the following terminals at the ECM connector.
- For the 91-4 and 91-8 codes terminal 66 of the A-C1 ECM connector.
- For the 29-4 code, terminal 94 of the A-C2 ECM connector
Short Circuit
Results: The resistance measured more than 100k ohms.
The signal wire is not shorted to the engine ground.
Proceed to Test Step 5.
Results: The resistance measured less than 100k ohms.
The signal wire is shorted to the engine ground.
Repair: Repair or replace the wiring harness.
5. Check the Wiring Harness for a Pin to Pin Short Circuit
A. Turn the main disconnect switch to the OFF position.
B. Disconnect the wiring harness from the ECM.
C. Measure the resistance between the following ECM connector
terminals:
- For the 91-4 and 91-8 codes, terminal 66 of the A-C1 ECM connector and all
