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



锟斤拷 If 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



锟斤拷 If 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.



锟斤拷 If 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.



锟斤拷 If 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.



* Outside Rearview Mirror Motor Replacement (See: Body and Frame/Mirrors/Power Mirror Motor/Service and Repair)



* Control Module References (See: Testing and Inspection/Programming and Relearning) for DDM or PDM replacement, setup, and
