Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage.
- Visually inspect for obstructions preventing column movement. VISUAL INSPECTION CHART Mechanical Electrical Steering column control switch Adjustable steering column tilt motor Adjustable steering column telescope motor (part of the steering column assembly) Steering column assembly Wiring, terminals or connectors SCCM
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
- If the scan tool does not communicate with the VCM: Check the VCM connection to the vehicle. Check the scan tool connection to the VCM. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-494551) , No Power To The Scan Tool, to diagnose no power to the scan tool.
- If the scan tool does not communicate with the vehicle: Verify the ignition is ON. Verify the scan tool operation with a known good vehicle. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-494551) , The PCM Does Not Respond To The Scan Tool, to diagnose no response from the PCM.
- Carry out the network test. If the scan tool responds with no communication for one or more modules, refer to «MODULE COMMUNICATIONS NETWORK»(ref-494551) . If the network test passes, retrieve and record Continuous Memory Diagnostic Trouble Codes (CMDTCs).
- Clear the continuous DTCs and carry out the self test diagnostics for the SCCM.
- If the DTCs retrieved are related to the concern, go to «Steering Column Control Module (SCCM) DTC Chart»(ref-494604-S14788612902012081400000) . For all other SCCM DTCs, refer to the Master DTC Chart in «STEERING COLUMN SWITCHES»(ref-494582) .
- If no DTCs related to the concern are retrieved, GO to «Symptom Chart»(ref-494604-S31472920052012081400000) .

DTC Charts
Note. This module utilizes a 5-character DTC followed by a 2-character failure-type code. The failure-type code provides information about specific fault conditions such as opens or shorts to ground. Continuous Memory Diagnostic Trouble Codes (CMDTCs) have an additional 2-character DTC status code suffix to assist in determining DTC history.
Note. Network DTCs (U-codes) are often a result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures such as module reprogramming often set network DTCs. Replacing a module to resolve a network DTC is unlikely to resolve the concern. To prevent repeat network DTC concerns, inspect all network wiring, especially connectors. Test the vehicle battery, refer to BATTERY, MOUNTING AND CABLES .
