Circuit/System Verification

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.

Circuit/System Testing

1. Ignition OFF, disconnect the X3 harness connector at the appropriate door module.

2. Ignition ON, verify a test lamp does not illuminate between the following control circuit terminals and ground:

* Control circuit terminal 1

* Control circuit terminal 2

* Control circuit terminal 6

瀚慖f the test lamp illuminates, test the appropriate control circuit for a short to voltage.

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

* Control circuit terminal 1

* Control circuit terminal 2

* Control circuit terminal 6

瀚慖f less the specified value, test the appropriate control circuit for a short to ground.

4. Test for 40-100 ohms between the control circuit terminal 1 and the control circuit terminal 6.

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. Test for 40-100 ohms between the control circuit terminal 2 and the control circuit terminal 6.

瀚慖f not within the specified range, test both control circuit for an open/high resistance. If the circuits test normal, test or replace the

rearview mirror.

6. If all circuits test normal, replace the door module.

Repair Instructions

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
