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 

      • Go to step  5
  2. CHECK FOR SHORTED SQUIB CIRCUITS IN PASSENGER 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 Passenger Airbag Squib connector.
      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 the connectors - Clean and repair as necessary.
    2. Connect the SRS Load Tool kit 8443A to the Passenger Airbag Squib 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's.

      Does the scan tool display: B1B0F-PASSENGER AIRBAG SQUIB 2 CIRCUIT SHORTED TOGETHER?

      Yes 

      • Go to step  3

      No 

  3. CHECK (R64) PASSENGER SQUIB 2 LINE 1 CIRCUIT FOR A SHORT TO (R62) PASSENGER SQUIB 2 LINE 2 CIRCUIT

    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 8443A Load Tool from the Passenger Airbag Squib connector.
    2. Disconnect the ORC connectors.
      NOTE: Check connectors - Clean and repair as necessary.
    3. Connect the 8443-24 Load Tool ORC Adaptor to the ORC C2 connector.
    4. Measure the resistance between the (R64) Passenger Squib 2 Line 1 circuit and the (R62) Passenger Squib 2 Line 2 circuit at the Passenger Airbag Squib connector.

      Is the resistance less than or equal to the range of 1.24 - 1.71 Ohms?

      Yes 

      No 

      • Go to step  4
  4. REPLACE THE ORC 
    WARNING: If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.

    Repair 

  5. STORED ORC DTC 
    1. With the scan tool, record and erase all DTCs from all Airbag System Modules.
    2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
      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.
    3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
    4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
    5. The following additional checks may assist you in identifying a possible intermittent problem.
    6. Reconnect any disconnected components and harness 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.
    7. With the scan tool monitor active codes as you work through the following steps.
    8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
    9. If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
    10. If only stored codes return continue the test until the problem area has been isolated.
    11. In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

      Are any ACTIVE DTCs present?

      Yes 

      No 

      • No problem found at this time. Erase all codes before returning vehicle to customer.
