Folding Mirror Motor Unfold Control 1 1 - -
1. Power Folding Mirror Inoperative


Circuit/System Description

The mirror select and fold/unfold switches are inputs to the mirror control module which communicates with the memory seat module through a serial data circuit. When the memory seat module receives a fold/unfold signal from the mirror control module, the memory seat control module will send a fold or unfold command back to the left mirror control module and passenger window switch. The mirror control module and passenger window switch control the fold/unfold motors through bi-directional control circuits.

Diagnostic Aids


Power folding mirror feature only available with RPO DR4 mirrors.

Power folding mirrors can only operate when the mirror selector switch is in the middle position.

Circuit/System Verification


1. Observe the scan tool Mirror Select Switch parameter while operating the switch between left, right, and none/fold. The reading should change between Left, Right, and None/Fold.

2. If the reading does not change between the specified values replace the S52 outside rearview mirror switch.

3. Command the driver and passenger mirrors to Fold and Unfold with a scan tool. Both mirrors should move in the commanded direction.


Circuit/System Testing


1. Ignition OFF, disconnect the X2 harness connector at the appropriate A9 outside rearview mirror.

2. Connect a test lamp between control circuit terminal 5 and control circuit terminal 6.

3. Command the driver and passenger mirrors to Fold and Unfold with a scan tool. 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 ground or an open/high resistance on either control circuit. If the circuits test normal, replace the appropriate switch.

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