CHECK THE (A929) FUSED B(+) CIRCUIT FOR AN OPEN
1. Turn the ignition off.
2. Disconnect the Steering Column Control Module (SCCM) harness connector.
3. Turn the ignition on.
4. Measure the voltage between ground and the (A929) Fused B(+) circuit at the SCCM harness connector.
  Is the voltage above 9.0 volts?
  
  Yes
  - Go To 3
  No
  - Repair the open or short to ground in the (A929) Fused B(+) circuit.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
CHECK THE (Z912) GROUND CIRCUIT FOR AN OPEN

2. Measure the voltage between ground and the (D403) LIN BUS 3 circuit at the SCCM harness connector.
  Is the voltage above 5.0 volts?
  
  Yes
  - Replace the Steering Column Control Module (SCCM) in accordance with the Service Information. Refer to MODULE, STEERING COLUMN CONTROL, REMOVAL .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Go To 5
CHECK THE (D403) LIN BUS 3 CIRCUIT FOR AN OPEN
1. Turn the ignition off.
2. Disconnect the BCM C5/E harness connector.
3. Measure the resistance of the (D403) LIN Bus 3 circuit between the SCCM harness connector and the BCM C5/E harness connector.
  Is the resistance above 3.0 Ohms?
  
  Yes
  - Repair the open in the (D403) LIN Bus 3 circuit.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Replace the Body Control Module (BCM) in accordance with the Service Information. Refer to MODULE, BODY CONTROL, REMOVAL .
