NOTE:
A dirty (partial) ground can cause abnormal conditions within a system. Ensure the module has a good ground before continuing.
1. Turn the ignition off.
2. Disconnect the WCM harness connector.
3. Using a 12 volt test light connected to ground, probe the Fused Ignition Switch Output (Run-Start) circuit in the WCM harness connector.
  Does the test light illuminate brightly?
  
  Yes
  - Repair the Fused Ignition Switch Output (Run-Start) circuit for a short to voltage.
  - Perform the WCM VERIFICATION TEST. Refer to STANDARD PROCEDURE - WIRELESS CONTROL MODULE (WCM) VERIFICATION .
  No
  - Replace and program the SKREEM in accordance with the Service Information.
