### Circuit/System Verification

Ignition ON, operate the mirror switch to the fold and extend positions. The outside rearview mirrors should fold and extend.

### Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the appropriate A9 outside rearview mirror.
2. Connect a test lamp between control circuit terminal 4 and control circuit terminal 5.
3. Operate the mirror switch to the fold and extend positions. The test lamp should turn ON when commanding the fold and extend states.

⇒ | 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.

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