2. Inspect the components of the exterior mirror system to determine if any of the mechanical or electrical concerns apply:
3. If the vehicle is equipped with memory exterior mirrors and the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel. Select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
- check to make sure the program card is correctly installed.
- check the connections to the vehicle.
- check the ignition switch position.

4. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
5. Carry out the DATA LINK DIAGNOSTICS test. If the diagnostic tool responds with:
- CAN, UBP or ISO circuit fault; All ECUs NO RESP/NOT EQUIP, refer to Information Bus (Module Communications Network).
- NO RESPONSE/NOT EQUIPPED for DSM, go to Body Control Systems (Multifunction Electronic Control Module).
- SYSTEM PASSED for the DSM, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the DSM.

6. If the DTCs retrieved are related to the concern, go to DSM Diagnostic Trouble Code (DTC) Index. Driver Seat Module (DSM) Diagnostic Trouble Code (DTC) Index
7. If DTCs are retrieved that are not found in the DSM Diagnostic Trouble Code (DTC) Index, refer to the master DSM Diagnostic Trouble Code (DTC) Index in Body Control Systems (Multifunction Electronic Control Module).
8. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
9. If no DTCs related to the concern are retrieved, refer to the Symptom Chart. Symptom Related Diagnostic Procedures
