Troubleshooting Test Steps Values Results
1. Check for Active Diagnostic Codes and Check for Logged Diagnostic Codes
A. Connect Cat® Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools", if necessary.
B. Download the "Product Status Report" from the engine ECM before performing any troubleshooting or clearing diagnostic trouble codes.
C. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note. Wait at least 30 seconds in order for diagnostic codes to become active.
D. Select diagnostic tests from Cat ET.
E. Select the "Override Parameters" screen on Cat ET.
F. Activate the override for the circuit that is being tested.
G. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note: Wait at least 30 seconds in order for the diagnostic code to become active.
H. Deactivate the override.
I. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note: Wait at least 30 seconds in order for the diagnostic codes to become active.
Logged Diagnostic Codes
Or
Active Diagnostic Codes
Results: A diagnostic code is logged but is not active.
Repair: Do not troubleshoot a logged code unless the code relates to an operator complaint. If the code is logged and the code does not relate to an operator complaint, clear the code.
If the logged code relates to this procedure, inspect the electrical connectors and the wiring for the circuit.
Refer to Troubleshooting, "Electrical Connectors - Inspect"
Results: A -5 diagnostic code is active at this time.
Proceed to Test Step 2.
Results: A -6 diagnostic code is active at this time.
Proceed to Test Step 5.
2. Inspect the Electrical Connectors and the Wiring
A. Check the harness and the wiring for abrasion and for pinch points.
B. Thoroughly inspect all connectors that are in the circuit. Refer to Troubleshooting, "Electrical Connectors - Inspect " for details.
-5 code
Results: The connectors and wiring are OK.
Proceed to Test Step 3.
Results: The connectors and/or wiring are Not OK.
Repair: Repair the connectors or wiring and/or replace the connectors or wiring.
3. Determine if the Heater has an Open Circuit Condition
A. Remove the electrical power from the ECM.
B. Disconnect the electrical connector from the heater of the circuit being tested.
C. Using appropriate terminals, fabricate a jumper wire and short the harness connector.
D. Restore the electrical power to the ECM.
E. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note. Wait at least 30 seconds in order for the diagnostic codes to become active.
F. Select diagnostic tests from Cat ET.
G. Select the "Override Parameters" screen on Cat ET.
H. Activate the override for the circuit that is being tested.
I. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note: Wait at least 30 seconds in order for the diagnostic code to become active.
J. Deactivate the override.
K. Monitor the active diagnostic code screen on Cat ET. Record any active diagnostic codes.
Note: Wait at least 30 seconds in order for the diagnostic code to become active.
L. Remove the electrical power from the ECM.
M. Restore the wiring to the original configuration.
-5 code
Results: A -5 diagnostic code is active when the connector is disconnected. A -6 diagnostic code is active when the jumper wire is shorting the circuit.
Repair: The wiring harness and the ECM are OK. The open circuit is in the heater. Perform the following repair:
1. Temporarily connect a new heater.
2. Recheck the circuit in order to ensure that the original problem is resolved with the installation of the new heater.
3. If the problem is resolved with the new heater, reinstall the suspect heater. If the problem returns with the installation of the suspect heater, permanently install the new heater.
