The folding (RPO DL3) and telescoping (RPO DPF) mirror system requires signals from two separate switches. The mirror select switch must be in the neutral position and the mirror direction switch must be activated to either the left or right position. Pressing the left side of the mirror direction switch will unfold the mirrors (RPO DL3) or extend the mirrors (RPO DPF). Pressing the right side of the mirror direction switch will fold the mirrors (RPO DL3) or retract the mirrors (RPO DPF). Both switches are integrated into the DDM and provide direct signals.

Upon receipt of the required switch inputs, the driver door module (DDM) will supply battery voltage and ground to the driver mirror fold/telescope motor control circuits to perform the requested folding/telescope function. The DDM will also send a serial data message to the front passenger door module (FPDM) indicating the requested function. The FPDM will supply battery voltage and ground to the passenger mirror fold/telescope motor control circuits to perform the requested folding/telescope function.

Description and Operation

Outside Mirror Description and Operation

Electrical Information Reference

1. Ignition OFF, disconnect the harness connector at the applicable door module.
2. Ignition ON, verify a test lamp does not illuminate between each of the following circuits and ground:

•	DDM - Control circuit terminal 6 and 1

•	FPDM - Control circuit terminal 4 and 3

⇒	If the test lamp illuminates, test both control circuits for a short to voltage. If the circuits test normal, test or replace the appropriate folding mirror motor (RPO DL3) or telescoping mirror motor (RPO DPF).

3. Ignition OFF, test for infinite resistance between the following circuits and ground:

•	DDM - Control circuit terminal 6 and 1

•	FPDM - Control circuit terminal 4 and 3

⇒	If less than the specified range, test both control circuits for a short to ground. If the circuits test normal, test or replace the appropriate folding mirror motor (RPO DL3) or telescoping mirror motor (RPO DPF).

4. Test for less than 3.0 ohms of resistance between the following circuits:

•	DDM - Control circuit terminals 6 and 1

•	FPDM - Control circuit terminals 4 and 3

⇒	If greater than the specified range, test both control circuits for an open/high resistance. If the circuits test normal, test or replace the appropriate folding mirror motor (RPO DL3) or telescoping mirror motor (RPO DPF).

5. If all circuits test normal, test or replace the appropriate door module.
