J1939 Code and Description Comments
105-3
Engine Intake Manifold #1 Temperature : Voltage Above Normal The Electronic Control Module (ECM) detects signal voltage that is not in the acceptable range.
The value of the parameter is set to a default value.
The code is logged.
105-4
Engine Intake Manifold #1 Temperature : Voltage Below Normal The ECM detects signal voltage that is not in the acceptable range.
The value of the parameter is set to a default value.
The code is logged.
110-3
Engine Coolant Temperature : Voltage Above Normal The ECM detects signal voltage that is not in the acceptable range.
The value of the parameter is set to a default value.
The code is logged.
Note: For a 110-3 code, start the engine and let the engine idle for 7 minutes. The engine must be running for at least 7 minutes in order for the diagnostic to run.
110-4
Engine Coolant Temperature : Voltage Below Normal The ECM detects signal voltage that is not in the acceptable range.
The value of the parameter is set to a default value.
The code is logged.
171-3
Ambient Air Temperature : Voltage Above Normal The ECM detects signal voltage that is not in the acceptable range.
The value of the parameter is set to a default value.
The code is logged.
171-4
Ambient Air Temperature : Voltage Below Normal The ECM detects signal voltage that is not in the acceptable range.
The value of the parameter is set to a default value.
The code is logged.
175-3
Engine Oil Temperature 1 : Voltage Above Normal The ECM detects signal voltage that is not in the acceptable range.
The value of the parameter is set to a default value.
The code is logged.
175-4
Engine Oil Temperature 1 : Voltage Below Normal The ECM detects signal voltage that is not in the acceptable range.
The value of the parameter is set to a default value.
The code is logged. The sensor signal for the passive sensor is routed from the ECM to terminal 1 of the sensor connector. The sensor return for the passive sensors is routed from the ECM to terminal 2 of the sensor connector.When the ECM detects voltage that is above a threshold on the signal wire, the ECM activates a high voltage -3 diagnostic code. When the ECM detects voltage that is below a threshold on the signal wire, the ECM activates a low voltage -4 diagnostic code.Note: There may be a delay of 30 seconds or more in order for Cat® Electronic Technician (ET) to display an active diagnostic code. When you check for a diagnostic code, be sure to wait at least 30 seconds.

Troubleshooting Test Steps Values Results
1. 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: A -3 code is active.
Proceed to Test Step 2.
Result: A -4 code is active.
Proceed to Test Step 3.
Result: For a code that is logged, but not currently active.
Proceed to Test Step 4.
2. Create a Short at the Sensor Connector
A. Turn the main disconnect switch to the OFF position.
B. Disconnect the sensor with the active -3 code.
C. Install the jumper wire between the following terminals at the sensor connector:
- Terminal 1 (sensor signal) and Terminal 2 (sensor return)
D. Connect Cat ET.
E. Use Cat ET to monitor the following:
- -4 code
F. Turn the main disconnect switch to the OFF position.
Create a Short
Result: The -3 code remains active.
Repair: There is an open in the wiring harness. Repair or replace the wiring harness.
Verify that the repair eliminated the problem.
Result: A -4 code became active.
Repair: The wiring harness is OK. Replace the sensor.
Verify that the repair eliminated the problem.
3. Create an Open at the Sensor Connector
A. Turn the main disconnect switch to the OFF position.
B. Disconnect the sensor with the active -4 code.
C. Connect Cat ET.
D. Use Cat ET to monitor the following:
- -3 code
Note: For a 110-3 code, start the engine and let the engine idle for 7 minutes. The engine must be running for at least 7 minutes in order for the diagnostic to run.
E. Turn the main disconnect switch to the OFF position.
Create an Open
Result: The -4 code remains active.
Repair: There is an open in the wiring harness. Repair or replace the wiring harness.
Verify that the repair eliminated the problem.
Result: A -3 code became active.
Repair: The wiring harness is OK. Replace the sensor.
Verify that the repair eliminated the problem.
If the procedure did not correct the issue, contact your Cat dealer Technical Communicator (TC). For further assistance, your TC can confer with the Dealer Solutions Network (DSN).
