Diagnostic Test

  1. TEST FOR INTERMITTENT CONDITION 
    NOTE:

    Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.

    1. Turn the ignition on.
      NOTE:

      Make sure the Ignition Off Draw (IOD) fuse is installed and battery voltage is between 10.0 and 16.0 volts.

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

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

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

      Yes 

      • The no response condition is not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.

      No 

      • Go To  2.
  2. CHECK THE (A931) FUSED B(+) CIRCUIT FOR AN OPEN OR SHORT

    1. Turn the ignition off.
    2. Disconnect the PCM C1 harness connector.
    3. Using a 12-volt test light connected to ground, check the (A931) Fused B(+) circuit.

      Does the test light illuminate brightly?

      Yes 

      • Go To  3.

      No 

      • Repair the open or short in the (A931) Fused B(+) circuit.
      • Perform the POWERTRAIN VERIFICATION TEST. Refer to appropriate Engine Performance Powertrain Module Diagnostic information. .
  3. CHECK THE (Z932) GROUND CIRCUIT FOR AN OPEN
