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.

    Turn the ignition on.

    NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.

    With the scan tool, select ECU View.

    NOTE: A red X will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.

    Does the scan tool display a red X next to the module? 

    Yes 

    1. Go To step  2.

    No 

    1. 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.
  2. (A415) FUSED B(+) CIRCUIT OPEN OR SHORTED

    Turn the ignition off.

    Disconnect the Intrusion Transceiver Module C1 and C2 harness connectors.

    Using a 12-volt test light connected to ground, check the (A415) Fused B(+) circuit.

    Does the test light illuminate brightly? 

    Yes 

    1. Go To step  3.

    No 

    1. Repair the (A415) Fused B(+) circuit for an open or short.
    2. Perform BODY VERIFICATION TEST - VER 1 .
  3. (Z941) GROUND CIRCUITS OPEN

    Using a 12-volt test light connected to 12-volts, check the (Z941) ground circuits.

    Does the test light illuminate brightly for each circuit? 

    Yes 

    1. Go To step  4.

    No 

    1. Repair the (Z941) ground circuits for an open.
    2. Perform BODY VERIFICATION TEST - VER 1 .
  4. (D55) AND (D54) CAN B BUS CIRCUITS OPEN

    NOTE: One open circuit will not cause this condition.

    Measure the voltage between the (D54) CAN B Bus (-) circuit and ground.

    Measure the voltage between the (D55) CAN B Bus (+) circuit and ground.

    Is there any voltage present on either circuit? 

    Yes 

    1. Replace the Intrusion Transceiver Module in accordance with the service information.
    2. Perform BODY VERIFICATION TEST - VER 1 .

    No 

    1. Repair the (D55) and (D54) CAN B Bus circuits for an open. Inspect the connector for damage.
    2. Perform BODY VERIFICATION TEST - VER 1 .
