Diagnostic Test

INTERMITTENT DTC
1. With the scan tool, erase the WIN DTCs.
2. Turn the ignition off and remove the key.
3. Arm the VTSS and wait one minute.
4. Disarm the VTSS and turn the ignition on.
5. With the scan tool, read the active DTCs.
  Does the scan tool display: U0236-LOST COMMUNICATION WITH COLUMN LOCK MODULE active?
  
  Yes
  - Go to Step 2.
  No
  - Test complete, the condition or conditions that originally set this DTC are not present at this time. Using Figure as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and poor pin fit.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .

1. Gain access to the Steering Column Lock Module.
2. Disconnect the Steering Column Lock Module harness connector.
3. Using a 12-volt test light connected to ground, check the (A106) Fused B(+) circuit in the Steering Column Lock Module harness connector.
  Does the test light illuminate brightly?
  
  Yes
  - Go to Step 3.
  No
  - Repair the (A106) Fused B+ circuit for an open.
  - Perform the BODY VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .

1. Using a 12-volt test light connected to ground, check the (F892) Ignition Switch Output (Key-In) circuit.
2. Be sure the ignition is on. The light should illuminate brightly for approximately 30 seconds when the Fobik is turned off and removed.
3. Turn the ignition off, remove the Fobik and observe the test light.
  Did the test light illuminate brightly for approximately 30 seconds when the ignition was turned off and the key removed?
  
  Yes
  - Go to Step 5.
  No
  - Go to Step 7.
