-
Install the test box.
If the manufacturers test box is not being used. Perform the following step.
-
Remove the Engine Control Module (ECM) J623.
-
Using a Multimeter, check the Engine Coolant Temperature (ECT) Sensor G62 electrical harness connector terminals to the Engine Control
Module (ECM) J623 electrical harness connector T121 terminals for resistance.

Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If no malfunction is found in the wiring:
-
Erase the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04 - Erase DTC Memory
-
Perform a road test to verify repair.
If the DTC does not return:
Repair complete, Generate readiness code. See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
-
End diagnosis.

-
Assembly is performed in the reverse of the removal.
Final procedures
After repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 03 - Read DTC Memory
2. If necessary, erase the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04 - Erase DTC Memory
3. If the DTC memory was erased, generate readiness code. See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
End of diagnosis
