Action Taken When the DTC Sets
Power folding mirror operations are suspended as long as the fault is present.
Conditions for Clearing the DTC
* A current DTC will clear when the fault is no longer present.
* A history DTC will clear after 40 fault free ignition cycles.

Circuit/System Verification
Ignition ON, using the folding mirror switch, the left and right rearview mirrors should extend and retract as commanded.
Circuit/System Testing
1. Ignition OFF, disconnect the X7 harness connector at the appropriate door module.
2. Ignition ON, verify a test lamp does not illuminate between the following circuit terminals and ground:
* Control circuit terminal 1
* Control circuit terminal 2
瀚慖f the test lamp illuminates, test the appropriate circuit for a short to voltage.
3. Ignition OFF, test for infinite resistance between the following circuits and ground:
* Control circuit terminal 1
* Control circuit terminal 2
瀚慖f less than the specified value, test the appropriate circuit for a short to ground. If the circuits test normal, test or replace the rearview
mirror.
4. Test for 5-15 ohms between the control circuit terminal 1 and the control circuit terminal 2.
瀚慖f not within the specified range, test both control circuits for an open/high resistance. If the circuits test normal, test or replace the
rearview mirror.
5. If all circuits test normal, replace the appropriate door module.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
