Circuit/System Verification

Ignition ON, operate the mirror switch fold/unfold functions. The outside mirrors should fold and unfold.

Note

Circuit/system verification must be carried out before circuit/system testing.


Circuit/System Testing


1. Ignition OFF, disconnect the harness connector at the appropriate A9 outside rearview mirror.

2. Connect a test lamp between the control circuit terminal 9 and the control circuit terminal 10.

3. Operate the outside mirror switch fold/unfold functions. The test lamp should turn ON when commanding the fold and unfold states.

4. If the test lamp remains OFF during either of the commands, test for a short to voltage, short to ground, or an open/high resistance on either control circuit. If the circuits test normal, replace the S52 outside mirror switch.

5. If all circuits test normal, test or replace the A9 outside rearview mirror.


Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
