Steering Column Switch

Inspection and Verification
1. Verify the customer's concern by operating the steering column switch to duplicate the condition.





2. Inspect to determine if one of the mechanical or electrical concerns is present.
3. If inspection reveals obvious concern(s) that can be readily identified, repair as required.
4. If the concern remains after the inspection, connect scan tool to the data link connector (DLC) located beneath the instrument panel to carry out DATA LINK DIAGNOSTIC TEST. For additional information, refer to Module Communications Network. If the scan tool responds with NO RESPONSE/NOT EQUIPPED for instrument cluster module (ICM). If the DATA LINK DIAGNOSTIC TEST is passed for the ICM, retrieve continuous diagnostic trouble codes (DTCs) and execute Self Test Diagnostics for the ICM. For additional information, refer to Module Communications Network.
5. If the self test is passed and no diagnostic trouble codes (DTCs) are retrieved, go to Symptom Chart to continue diagnostics.
6. If diagnostic trouble codes (DTCs) are retrieved, go to the Instrument Cluster Module (ICM) Diagnostic Trouble Code (DTC) Index to continue diagnostics. Instrument Cluster Module (ICM) Diagnostic Trouble Code Index
7. If the instrument cluster module (ICM) cannot be accessed by the scan tool.
