Turn the keyswitch to the OFF position.
Disconnect the GCU.
Measure the voltage between pin 4 and pin 5 on the harness connector for the GCU.Expected Result:The voltage measurement should be 10 to 14 VDC.Results:
OK - The GCU is correctly grounded Proceed to Test Step 11.
Not OK - The GCU is not correctly grounded. The fault is in the wiring between pin 5 on the harness connector for the GCU and P1:41.Repair: Repair the faulty wiring or replace the faulty wiring. Use the electronic service tool to override the glow plug start aid and verify that the repair eliminates the fault.Clear all logged diagnostic codes.STOPTest Step 6. Check That the Diagnostic Code Is Still Active
Turn the keyswitch to the ON position.
Use the electronic service tool to override the glow plug starting aid.
Check for active diagnostic codes.
Use the electronic service tool to turn off the glow plug starting aid.
Turn the keyswitch to the OFF position.Results:
A 676-5 diagnostic code is active - Proceed to Test Step 7.
A 676-6 diagnostic code is active - Proceed to Test Step 9.
A 676-19 diagnostic code is active - Proceed to Test Step 11.Test Step 7. Create a Short Circuit at the Harness Connector for the GCU
Turn the keyswitch to the OFF position.
Disconnect the GCU.
Fabricate a jumper wire that is 15 cm (6 inch) long.
Install the jumper wire between pin 5 and pin 8 on the harness connector for the GCU.
Turn the keyswitch to the ON position.
Use the electronic service tool to override the glow plug starting aid.
Check for active diagnostic codes.
Use the electronic service tool to turn off the glow plug starting aid.
Turn the keyswitch to the OFF position.
Remove the jumper wire.Results:
A 676-6 diagnostic code is active with the jumper installed. - There may be a fault in the GCU.Repair: Replace the GCU.Use the electronic service tool to override the glow plug starting aid and verify that the repair eliminates the faultClear all logged diagnostic codes.STOP
A 676-5 diagnostic code is active with the jumper installed. - The GCU is OK. Proceed to Test Step 8.Test Step 8. Check the Control Wire Between the GCU and the ECM
Turn the keyswitch to the OFF position.
Disconnect the GCU. Disconnect the P1/J1 connector.
Measure the resistance between pin 8 on the harness connector for the GCU and P1:52.Expected Result:The resistance is less than 2 Ohms.Results:
OK - The control wire is OK.Repair: Perform the following repair:
Make sure that the latest flash file for the application is installed in the ECM. Refer to Troubleshooting, "Flash Programming".
Contact the Technical Communicator at a Cat Dealer.Note: This consultation can greatly reduce the repair time.
If the Technical Communicator recommends the use of a replacement ECM, install a replacement ECM. Refer to Troubleshooting, "Replacing the ECM".
Use the electronic service tool to override the glow plug starting aid.
Use the electronic service tool to recheck the system for active diagnostic codes.
Use the electronic service tool to turn off the glow plug starting aid.
If the fault is eliminated with the replacement ECM, reconnect the suspect ECM. If the fault returns
