Diagnostic Test

WARNING: This page is about a different car, the 2007 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.
  1. 1) TEST FOR INTERMITTENT CONDITION 

    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. 2) GROUND CIRCUIT OPEN 
    WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

    Disconnect the Occupant Restraint Controller Module C1-A harness connector.

    Connect the appropriate Load Tool ACM Adapter to the ORC connector.

    Using a 12-volt test light connected to 12-volts, check the ground circuit.

    Does the test light illuminate brightly? 

    Yes 

    1. Go To step  3).

    No 

    1. Repair the ground circuit for an open.
    2. Perform BODY VERIFICATION TEST - VER 1 .
  3. 3) FUSED IGNITION SWITCH OUTPUT (RUN) CIRCUIT OPEN OR SHORTED 
    NOTE: Check the Ignition Switch for any ignition related DTCs before proceeding. If set. Refer to DIAGNOSIS AND TESTING .
    WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

    Using a 12-volt test light connected to ground, check the Fused Ignition Switch Output (Run) circuit.

    Does the test light illuminate brightly? 

    Yes 

    1. Go To step  4).

    No 

    1. Repair the Fused Ignition Switch Output (Run) circuit for an open or short.
    2. Perform BODY VERIFICATION TEST - VER 1 .
  4. 4) FUSED IGNITION SWITCH OUTPUT (RUN/START) CIRCUIT OPEN OR SHORTED 

    Using a 12-volt test light connected to ground, check the Fused Ignition Switch Output (RUN/START) circuit.

    Does the test light illuminate brightly? 

    Yes 

    1. Go To step  5).

    No 

    1. Repair the Fused Ignition Switch Output (RUN/START) circuit for an open or short.
    2. Perform BODY VERIFICATION TEST - VER 1 .
  5. 5) CAN B BUS CIRCUITS OPEN 
    WARNING: If the Occupant Restraint Controller is dropped at any time, it must be replaced. Failure to take the proper precautions could result in accidental airbag deployment and personal injury or death.
    NOTE: One open circuit will not cause this condition.

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

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

    Is there any voltage present on either circuit? 

    Yes 

    1. Replace the Occupant Restraint Controller Module in accordance with the service information.
    2. Perform BODY VERIFICATION TEST - VER 1 .

    No 

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