    1. Turn the ignition on.
      NOTE:

      Make sure the battery voltage is between 10.0 and 16.0 volts.

    2. With the scan tool, read the module status.
      NOTE:

      Check the BCM for any active CAN hardware DTCs, perform DTC before proceeding.

      Does the scan tool indicate that the module is active on the bus?

      Yes 

      • Go To  2.

      No 

      • The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals.
      • Perform the BODY VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  2. CHECK THE (A933) FUSED B(+) CIRCUIT FOR AN OPEN OR SHORT

    1. Turn the ignition off.
    2. Disconnect the TGW Module C2 harness connector.
    3. Using a 12-volt test light connected to ground, check the (A933) Fused B(+) circuit.

      Does the test light illuminate brightly?

      Yes 

      • Go To  3.

      No 

      • Repair the open or short in the (A933) Fused B(+) circuit.
