The driver door module (DDM) supplies battery positive voltage to the power mirror switch. When the mirror direction switch is placed in the up or down position, the appropriate signal circuit is switched to battery voltage. The driver door module senses the voltage change and activates the selected outside rearview mirror in the appropriate direction.

Battery voltage must be between 9-16 volts.

The DDM senses an active state on both the mirror switch left and right signal circuits greater than 3 seconds.

The DDM ignores the continuous inputs from the switch. The DDM will respond to all other valid switch inputs.

Command the left and right outside mirror to move up, down, left and right using the mirror directional switch. The mirror should move in the commanded direction.

1. Ignition OFF, disconnect the X5 harness connector at the DDM.
2. Ignition ON, verify the scan tool Mirror Motor parameter is Idle.

⇒	If not the specified value, replace the DDM.

3. Ignition OFF, connect the X5 harness connector at the DDM.
4. Ignition ON, observe the scan tool Mirror Motor parameter while cycling the mirror directional switch between the up, down, left and right positions. The parameter should change between Idle, Up, Down, Left, and Right.

⇒	If the parameter does not cycle between the specified values, replace the outside rearview mirror switch.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
