Diagnostic Test

WARNING: This page is about a different variant/trim than selected.
  1. VERIFY THE DTC IS ACTIVE 
    1. Ignition on, engine not running.
    2. With the scan tool, read the active DTC.
    3. Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 10 seconds.
    4. With the scan tool, read the active DTC.

      Is the DTC active at this time?

      Yes 

      • Go To  2.

      No 

      • Go To  7.

    1. Turn the ignition off.
    2. Disconnect the AWD Control Module harness connector.
    3. Ignition on, engine not running.
    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 

      • Go To  3.

      No 

      • Go To  4.

    1. Turn the ignition off.
    2. Disconnect the AWD Control Module harness connector.
    3. With a 12-volt test light connected to B+, check the (Z906) Ground 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 

      • Go To  5.

      No 

      • Repair the (Z906) Ground circuit for an open circuit or high resistance.
      • Refer to Standard Procedure  and perform the AWD CONTROL MODULE VERIFICATION TEST.

    1. Disconnect the TIPM C11 harness connector.
    2. Connect a jumper wire between the (F202) Ignition Switch Output (RUN/START) circuit and B(+) in the TIPM C11 harness connector.
    3. 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 

      • Go To  6.

      No 

      • Repair the (F202) Ignition Switch Output (RUN/START) circuit for an open circuit or high resistance.
      • Refer to Standard Procedure  and perform the AWD CONTROL MODULE VERIFICATION TEST.
  5. AWD CONTROL MODULE 
    NOTE:

    Before continuing, check the AWD Module harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

    1. Using the schematics as a guide, inspect the wire harness and connectors.
    2. Pay particular attention to all Power and Ground circuits.

      .

      Repair 

      • Replace the All Wheel Drive (AWD) Control Module in accordance with the Service information.
      • Refer to Standard Procedure  and perform the AWD CONTROL MODULE VERIFICATION TEST.
  6. TOTALLY INTEGRATED POWER MODULE 
    NOTE:

    Before continuing, check the TIPM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

    1. Using the schematics as a guide, inspect the wire harness and connectors.
    2. Pay particular attention to all Power and Ground circuits.

      Were any problems found?

      Repair 

      • Replace the Totally Integrated Power Module in accordance with the Service Information.
      • Refer to Standard Procedure and perform the BODY VERIFICATION TEST.
  7. INTERMITTENT WIRING AND CONNECTORS 
    1. The conditions necessary to set this DTC are not present at this time.
    2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
    3. Wiggle test the wiring harness and connectors while checking for shorted and open circuits.
    4. Using the scan tool, monitor the data related to this circuit while performing the wiggle test. Look for the data to change or for the DTC to reset.

      Were there any problems found?

      Yes 

      • Repair as necessary.
      • Refer to Standard Procedure  and perform the AWD CONTROL MODULE VERIFICATION TEST.
