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 for 1
second 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. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
