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 #B13 (#33) and door mirror terminal #13. Check for an open-circuit.

Replace the signal cable if a fault is found.

Try replacing the door mirror if no fault is found.

Remedy as necessary.
