If the specification was not obtained:
-
Check the wiring for an open circuit, a short circuit to Battery positive (+) or to Ground (GND).
-
Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-
If necessary, repair the wiring connection.
If the specification was obtained:

If the DTC returns and no malfunction is found in the wiring and voltage supply was OK:
-
Replace the Engine Control Module (ECM) J623.
-
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: Computers and Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 03 -
Read DTC Memory
2. If necessary, erase the DTC memory. See: Computers and Control Systems/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: Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive
Cycles and Readiness Codes
End of diagnosis
