The Driver Door Switch (DDS) and Passenger Door Switch (PDS) control the power folding or power extending functions of the outside rearview mirrors. The folding mirror motors are controlled by using bi-directional motor controls through the folding mirror motor retract control circuit and the folding mirror motor extend control circuit.

Scan Tool Reference

1. Ignition ON, observe the scan tool Mirror Fold Switch parameter while cycling the mirror fold switch between the extend and retract positions. The parameter should change between Idle, Extend, and Retract.

⇒	If the parameter does not cycle between the specified values, replace the DDS.

2. Command the power folding mirrors to extend and retract using the mirror fold switch. Both mirrors should extend and retract as commanded.

1. Ignition OFF, disconnect the X1 harness connector at the outside rearview mirror.
2. Install a test lamp between the control circuit terminal 1 and the control circuit terminal 2.
3. Ignition ON, commanded the mirrors to extend and retract using the power folding switch. The test lamp turn ON and OFF when changing between the commanded states.

⇒	If the test lamp is always ON, test both control circuits for a short to voltage. If the circuit tests normal, replace the appropriate door switch.

⇒	If the test lamp is always OFF, test both control circuits for a short to ground or an open/high resistance. If the circuit tests normal, replace the appropriate door switch.

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

1. Ignition OFF, disconnect the X1 harness connector at the outside rearview mirror.
2. Test for 6-8 ohms of resistance between the control terminal 1and the control terminal 2.

⇒	If not within the specified range, replace the outside rearview mirror motor.
