Diagnostic Test

WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
  1. DETERMINE ACTIVE OR STORED DTC 
    NOTE: Ensure the battery is fully charged.
    NOTE: The Scan Tool, SRS Airbag Load Tool MRL 8443A and DVOM are required to perform the following test.
    1. Select Active or Stored DTC.

      Is the DTC active or stored?

      ORC - ACTIVE DTC 

      • Go To step  2

      ORC - STORED DTC 

  2. CHECK FOR SHORTED SQUIB CIRCUITS IN DRIVER AIRBAG

    1. Disconnect the Driver Airbag Squib connectors.
      WARNING: Do not place an intact undeployed airbag face down on a hard surface, the airbag will propel into the air if accidentally deployed. Failure to follow these instructions may result in possible serious or fatal injury.
      NOTE: Check connectors - Clean and repair as necessary.
    2. Connect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-1 to the Driver Airbag Squib connectors.
      WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
    3. With the scan tool, read the active ORC DTCs.

      Does the scan tool display: B1B05 DRIVER AIRBAG SQUIB 2 CIRCUIT HIGH?

      Yes 

      • Go to step  3

      No 

        WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
      • Replace the Driver Airbag in accordance with the Service Information.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  3. CHECK CLOCKSPRING SQUIB CIRCUITS FOR A SHORT TO VOLTAGE

    WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
    1. Disconnect the SRS Load Tool Kit 8443A and the 8443-1 Jumper from the Driver Airbag Squib connectors.
    2. Remove the Steering Control Module from the steering column in accordance with the Service Information.
    3. Disconnect the Steering Control Module C1 connector.
      NOTE: Check the connectors - Clean and repair as necessary.
    4. With the Steering Control Module connector attached to the steering column, connect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-13 to the Steering Control Module C1 connector.
      WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
    5. With the scan tool, read the active ORC DTCs.

      Does the scan tool display: B1B05 DRIVER AIRBAG SQUIB 2 CIRCUIT HIGH?

      Yes 

      • Go to step  4

      No 

  4. CHECK (R63) DRIVER SQUIB 2 LINE 1 CIRCUIT AND (R61) DRIVER SQUIB 2 LINE 2 CIRCUIT FOR A SHORT TO VOLTAGE

    WARNING: Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
    1. Disconnect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-13 from the Steering Control Module C1 connector.
    2. Disconnect the ORC connectors.
      NOTE: Check the connectors - Clean and repair as necessary.
    3. Connect the SRS Load Tool Adapter 8443-24 to the ORC C2 connector.
      WARNING: Turn the ignition on, then reconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
    4. Measure the voltage of the (R63) Driver Squib 2 Line 1 circuit between the Steering Control Module connector and ground.
    5. Measure the voltage of the (R61) Driver Squib 2 Line 2 circuit between the Steering Control Module connector and ground.

      Is there any voltage present for either measurement?

      Yes 

        WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
      • Repair the Driver Squib 2 circuits with voltage present for a short to voltage.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

      No 

        WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment. Failure to follow these instructions may result in possible serious or fatal injury.
        WARNING: Turn the ignition off, disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
