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: Make sure that the battery is fully charged.
    NOTE: The scan tool, SRS Load Tool Kit 8443A, and DVOM are required to perform the following test.
    1. Turn the ignition on.

      Select ACTIVE or STORED DTC:

      ACTIVE DTC 

      • Go to step  2

      STORED DTC 

      • Go to step  5
  2. CHECK FOR SHORTED SQUIB CIRCUITS IN RIGHT SEAT AIRBAG

    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 Right Seat Airbag connector.
      WARNING: Do not place an intact non-deployed Seat Squib 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 the connectors - Clean and repair as necessary.
    2. Connect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-1 to the Right Seat Airbag 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.
    3. With the scan tool, read the active ORC DTC.

      Does the scan tool display: B1C2B-RIGHT SIDE SEAT THORAX SQUIB 1 LOW?

      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 Right Seat 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 FOR SHORTED RIGHT SEAT AIRBAG SQUIB CIRCUITS IN THE SEAT BACK

    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 Right Seat Airbag C323 connector (under Right Seat).
      NOTE: Check the connectors - Clean and repair as necessary.
    2. Connect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-20 to the C323 connector (Body Side).
      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 DTC.

      Does the scan tool display: B1C2B-RIGHT SIDE SEAT THORAX SQUIB 1 LOW?

      Yes 

      • Go to step  4

      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.
      • In accordance with Service Information repair or replace the Right Seat Airbag wiring harness (Side Airbag Jumper). Right Seat Airbag circuits shorted to ground between the C323 connector (Side Airbag Jumper) and the Right Seat Airbag connector.
      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

    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 8443-20 from the Right Seat Airbag connector.
    2. Disconnect the ORC connectors.
      NOTE: Check connectors - Clean and repair as necessary.
    3. Connect the SRS Load Tool Adapter 8443-24 to the ORC connectors.
    4. Measure the resistance of the (R6) Right Seat Squib 1 Line 2 circuit between the ORC 8443-24 Adaptor cavity 27 and ground.
    5. Measure the resistance of the (R8) Right Seat Squib 1 Line 1 circuit between the ORC 8443-24 Adaptor cavity 28 and ground.

      Is the resistance below 10K Ohms on either circuit?

      Yes 

      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 and serious or fatal injury.

      • Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure 
  5. CHECKING STORED OR INTERMITTENT CODES 
    NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to DIAGNOSTIC CODE INDEX  .
    1. With the scan tool, record and erase all Airbag System Module DTCs.
      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.
    2. Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chafed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.
    3. Reconnect all disconnected components and harness 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.

      WARNING: Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.
      • Wiggle the wiring harness and connectors of the related airbag circuit.
      • Continue the test until either a code becomes active or the problem area is isolated.
    5. In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question/causing the intermittent condition.

      Are any ACTIVE DTCs present?

      Yes 

      No
