1. Turn the ignition off.
2. Disconnect the TIPM C11 harness connector.
3. Disconnect the AWD Control Module harness connector.
4. With a 12-volt test light connected to ground, check the (F202) Ignition Switch Output (RUN/START) circuit in the AWD Control Module harness connector.
  NOTE:
  The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly?
  
  Yes
  - Repair the (F202) Ignition Switch Output (RUN/START) circuit for a short to voltage.
  - Perform the AWD CONTROL MODULE VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
