Checking the component
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can occur for a number of different reasons. The fault is evaluated depending on how it occurs.
Check the connector. Check for contact resistance and oxidation.
Check the signal cable between control module terminal #B9 (#29) and door mirror terminal #9. Check for a short-circuit to ground.
Replace the signal cable if a fault is found.
Try replacing the door mirror if no fault is found.
