1. Turn the ignition off.
2. Remove the Driver Airbag in accordance with the Service Information to gain access to the Steering Wheel Control Switches.
3. Disconnect the Left Steering Switch harness connector.
4. Disconnect the Right Steering Switch harness connector.
  NOTE: Before proceeding, thoroughly inspect the wiring harness and connectors between the Left Steering Switch and the Right Steering Switch for a short to ground or to any other circuit.
5. Measure the resistance between the (G206) EVIC Mux Signal 2 circuit and the (G907) EVIC/NAV Mux Return circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (G206) EVIC Mux Signal 2 circuit for a short to the (G907) EVIC/NAV Mux Return circuit.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go to step 3

1. Reconnect the Left Steering Switch harness connector.
2. Measure the resistance between the (G206) EVIC Mux Signal 2 circuit and the (G907) EVIC/NAV Mux Return circuit at the Right Steering Switch harness connector.
  Is the resistance approximately 10.00 K Ohms (+/- 10%)?
  
  Yes
  - Replace the Left Steering Switch in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Go to step 5
RIGHT STEERING SWITCH
1. Replace the Right Steering Switch in accordance with the Service Information.
2. Reconnect the C206 (LIN Bus) harness connector.
3. Turn the ignition on.
4. Press and release the Audio Switch several times.
5. With the scan tool, Clear Stored DTCs in the Steering Control Module.
6. With the scan tool, select Data Display and view the Audio switch data.
7. While monitoring the Audio switch data, press and release the Audio Switch several times.
  Does the Audio switch data change from Set to Not Set as the switch is pressed and released?
  
  Yes
  - Test Complete.
  No
  - Replace the Steering Control Module (SCM) in accordance with the Service Information.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
INTERMITTENT STEERING WHEEL CONTROL AUDIO SWITCH CIRCUIT DTC
1. The conditions necessary to set this DTC are not present at this time.
2. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
3. While monitoring the scan tool data relative to this circuit, wiggle test the wiring and connectors.
4. Look for the data to change or for the DTC to reset during the wiggle test.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Test complete.
