Circuit/System Verification
|
Ignition ON, operate the mirror switch fold/unfold functions. The outside mirrors should fold and unfold.
|
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.
|
Perform the
Diagnostic Repair Verification
after completing the diagnostic procedure.
