Diagnostic Test

  1. TEST FOR INTERMITTENT CONDITION 
    1. Turn the ignition on.
      NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
    2. With the scan tool, select System select.
    NOTE: If an ECU is grayed out, it is not communicating, indicating that the module is not active on the Bus network.

    Q: Is the ECU grayed out? 

    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.

    1. Turn the ignition off.
      NOTE: Check IPM fuses before continuing.
    2. Disconnect the Cluster harness connectors.
    3. Using a 12-volt test light connected to ground, check each (A924) (A920) (A117) Fused B (+) circuit.

    Q: Does the test light illuminate brightly for each circuit? 

    Yes : 

    • Go To 3

    No : 

    • Repair the (A924) (A920) (A117) Fused B (+) circuit for an open or short.
    • Perform BODY VERIFICATION TEST - VER 1 . (Refer to ELECTRONIC CONTROL MODULES/MODULE - FRONT CONTROL/DIAGNOSIS AND TESTING).
  3. (Z946) (Z948) GROUND CIRCUITS OPEN

    1. Using a 12-volt test light connected to 12-volts, check each (Z946) (Z948) ground circuit.

    Q: Does the test light illuminate brightly for each circuit? 

    Yes : 

    • Go To 4

    No : 

    • Repair the (Z946) (Z948) ground circuit for an open.
    • Perform BODY VERIFICATION TEST - VER 1 . (Refer to ELECTRONIC CONTROL MODULES/MODULE - FRONT CONTROL/DIAGNOSIS AND TESTING).
  4. (F21) (F983) FUSED IGNITION SWITCH OUTPUT CIRCUIT OPEN OR SHORTED

    1. Turn the ignition on.
      NOTE: Check IPM fuses before continuing.
    2. Using a 12-volt test light connected to ground, check each (F21) (F983) Fused Ignition Switch Output circuit.
    NOTE: The ignition must be in the start position to properly check the F21 circuit.

    Q: Does the test light illuminate brightly for each circuit? 

    Yes : 

    • Go To 5

    No : 

    • Repair the (F21) (F983) Fused Ignition Switch Output circuit for an open or short.
    • Perform BODY VERIFICATION TEST - VER 1 . (Refer to ELECTRONIC CONTROL MODULES/MODULE - FRONT CONTROL/DIAGNOSIS AND TESTING).
  5. (D55) AND (D54) CAN B BUS CIRCUITS OPEN 
    Fig 4: Checking CAN B Bus Circuits Open

    NOTE: One open circuit will not cause this condition.
    1. Measure the voltage between the (D54) CAN B Bus (-) circuit and ground.
    2. Measure the voltage between the (D55) CAN B Bus (+) circuit and ground.

    Q: Is there any voltage present on either circuit? 

    Yes : 

    • Replace the Instrument Cluster in accordance with the service information.
    • Perform BODY VERIFICATION TEST - VER 1 . (Refer to ELECTRONIC CONTROL MODULES/MODULE - FRONT CONTROL/DIAGNOSIS AND TESTING).

    No : 

    • Repair the (D55) and (D54) CAN B Bus circuits for an open. Inspect the connector for damage.
    • Perform BODY VERIFICATION TEST - VER 1 . (Refer to ELECTRONIC CONTROL MODULES/MODULE - FRONT CONTROL/DIAGNOSIS AND TESTING).
