An intermittent fault is one that has been registered but no longer remains. Intermittent faults may arise as the result of several different causes. The fault is assessed on a case by case basis.
Check driver door/passenger door module (DDM/PDM) connector #A13 and left rear door/right rear door module (LDM/RDM) connector #6 for contact resistance and oxidation. Check especially for damage.
Also check intermediate connectors for contact resistance, oxidation and damage.
Check the communication cable between the driver door/passenger door module (DDM/PDM) and the left rear door/right rear door module (LDM/RDM) for open-circuit.
Measure between:
- Driver door/passenger door module (DDM/PDM) #A13 (#13) and left rear door/right rear door module (LDM/RDM) #6.
Remedy as necessary.
