Diagnostic Codes Table    
CDL Code     J1939 Code     Code Description     Comments    
110-3     110-3     Engine Coolant Temperature Sensor : Voltage Above Normal     The code is logged if the engine has been running for more than 7 minutes and an open circuit has been detected.    
110-4     110-4     Engine Coolant Temperature Sensor : Voltage Below Normal     The code is logged. The ECM detects voltage that is not in the acceptable range.    
174-3     174-3     Fuel Temperature Sensor : Voltage Above Normal     The code is logged. The ECM will flag the fuel temperature as invalid data and the fuel temperature is set to a default value of
40 °C (104 °F).    
174-4     174-4     Fuel Temperature Sensor : Voltage Below Normal    
1836-3     1385-3     Auxiliary Temperature Sensor : Voltage Above Normal     The code is logged. The ECM will flag the temperature as invalid data and the temperature is set to a default value.    
1836-4     1385-4     Auxiliary Temperature Sensor : Voltage Below Normal     The code is logged. The ECM will flag the temperature as invalid data and the temperature is set to a default value.    
2526-3     172-3     Air Inlet Temperature Sensor : Voltage Above Normal     The code is logged.
The ECM detects voltage that is not in the acceptable range.    
2526-4     172-4     Air Inlet Temperature Sensor : Voltage Below Normal     The code is logged.
The ECM detects voltage that is not in the acceptable range.    
3372-3     2630-3     Engine Charge Air Cooler #1 Outlet Temperature Sensor : Voltage Above Normal     The code is logged.
The ECM detects voltage that is not in the acceptable range.    
3372-4     2630-4     Engine Charge Air Cooler #1 Outlet Temperature Sensor : Voltage Below Normal     The code is logged.
The ECM detects voltage that is not in the acceptable range.    
3386-3     412-3 (1)     EGR Temperature Sensor : Voltage Above Normal     The code is logged.
This code will not become active during Cold Mode. Run the engine to exit cold mode before troubleshooting a 3386-3 or 412-3 code.
The ECM detects voltage that is not in the acceptable range.    
3386-4     412-4 (1)     EGR Temperature Sensor : Voltage Below Normal     The code is logged.
The ECM detects voltage that is not in the acceptable range.    
3683-3     442-3     Auxiliary Temperature #2 : Voltage Above Normal     The code is logged.
The ECM detects voltage that is not in the acceptable range.    
3683-4     442-4     Auxiliary Temperature #2 : Voltage Below Normal     The code is logged.
The ECM detects voltage that is not in the acceptable range.    
( 1 ) This code cannot be cleared from the Cat ET "Logged" screen for 9600 hours after the code becomes logged.System OverviewThe sensor signal for the passive sensor is routed from the ECM to terminal 1 of each sensor connector. The sensor return for the passive sensors is routed to the ECM from terminal 2 of each sensor connector.Diagnostics on the Caterpillar Electronic Technician (ET)Wiggle Test - The Wiggle Test allows you to monitor the status of the signals from the sensors.For additional information regarding the Wiggle Test, refer to the documentation that accompanies the Cat ET software.

Troubleshooting Test Steps     Values     Results    
1. Check for Diagnostic Trouble Codes
A. Connect to Caterpillar Electronic Technician (ET).
B. Turn the keyswitch to the ON position.
C. Access the "Active Diagnostic Code" screen on Cat ET.
Wait at least 30 seconds in order for the diagnostic codes to become active.
D. Look for these active codes or logged codes:
1. -3
2. -4
   
Codes    
Result: A -3 diagnostic code is active.
Proceed to Test Step 2.
Result: A -4 diagnostic code is active.
Proceed to Test Step 3.
Result: To troubleshoot a logged 3386-3 or a 412-3 diagnostic code during cold mode, Proceed to Test Step 5.
This code will not become active during cold mode.
Result: For a diagnostic code that is logged but not currently active, Proceed to Test Step 4.
   
2. Create a Short at the Sensor Connector
A. Turn the keyswitch to the OFF position.
B. Disconnect the suspect sensor.
C. Install the jumper wire between terminal 1 (sensor signal) and terminal 2 (sensor return) at the sensor connector.
D. Turn the keyswitch to the ON position.
E. Monitor the diagnostic codes on Cat ET. Check for an active -4 diagnostic code for the suspect sensor.
Wait at least 30 seconds in order for the diagnostic codes to become active.
F. Turn the keyswitch to the OFF position.
   
Short circuit recognized    
Result: The -3 diagnostic code remains active for the suspect sensor.
There is an open in the harness. Repair the wiring or replace the harness.
Verify that the problem is resolved.
Result: A -4
