Diagnostic Test

INTERMITTENT DTC
1. With the scan tool, erase the current WCM DTCs.
2. Turn the ignition off.
3. Arm the Vehicle Theft and Security System (VTSS) and wait one minute.
4. Disarm the VTSS and turn the ignition on.
  Does the scan tool display the same DTC?
  
  Yes
  - Go to step 2
  No
  - The condition that caused this symptom is currently not present. Inspect the related wiring harness for a possible intermittent condition. Look for any chafed, pierced, pinched or partially broken wires.
  - Perform the WCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure .

1. Gain access to the Steering Column Lock Module.
2. Disconnect the Steering Column Lock Module connector.
3. Using a 12-volt test light connected to ground, check the (A952) Fused B(+) circuit in the Steering Column Lock Module connector.
  Does the test light illuminate brightly?
  
  Yes
  - Go to step 3
  No
  - Repair the (A952) Fused B(+) circuit for an open.
  - Perform the WCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure .

1. Using a 12-volt test light connected to ground, check the (A892) Ignition Switch Output (Key-In) circuit in the Steering Column Lock Module connector while fully inserting and removing the key from the Ignition Switch
  Does the test light toggle On and Off?
  
  Yes
  - Go to step 4
  No
  - Check the (A952) Fused B(+) circuit for an open to the ignition switch C2 connector, if OK check the (A892) Ignition Switch Output (Key-In) circuit from the Ignition Switch to the Steering Column Lock Module for an open, if that circuit is OK replace the Ignition Switch.
  - Perform the WCM VERIFICATION TEST. DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure .

  Does the test light illuminate brightly?
  
  Yes
  - Go to step 5
  No
  - Repair the (Z910) Ground circuit for an open.
  - Perform the WCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure .

1. Disconnect the Sentry Key Remote Entry/WCM harness connector.
2. Measure the resistance of the (D508) Tire Pressure Bus circuit between the WCM and the Steering Column Lock Module connectors.
  Is the resistance below 1.0 ohms?
  
  Yes
  - Replace the Steering Column Lock Module in accordance with the Service Information.
  - Perform the WCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure .
  No
  - Repair the (D508) Tire Pressure Bus circuit for an open.
  - Perform the WCM VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Wireless Control (WCM) - Standard Procedure .
