Diagnostic Test

  1. DETERMINE ACTIVE OR STORED DTC 
    NOTE: Ensure that 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. Turn the ignition on.

      Select ACTIVE or STORED DTC:

      ACTIVE DTC 

      • Go to step  2

      STORED DTC 

      • Go to step  5
  2. CHECK FOR OPEN SQUIB CIRCUITS IN LEFT SIDE CURTAIN 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 Left Side Curtain Airbag connector.
      WARNING: Do not place an intact non-deployed curtain 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 8443A Load Tool and 8443-8 Jumper to the Left Side Curtain 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 DTCs.

      Does the scan tool display: B1B1A-LEFT SIDE CURTAIN SQUIB 1 CIRCUIT OPEN?

      Yes 

      • Go to step  3

      No 

  3. CHECK (R3) LEFT CURTAIN SQUIB 1 LINE 1 CIRCUIT FOR AN OPEN

    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 and Jumper from the Left Side Curtain Airbag connector.
    2. Disconnect the ORC connectors.
      NOTE: Check connectors - Clean and repair as necessary.
    3. Connect the ORC 8443-25 Adaptor to the ORC connectors.
    4. Measure the resistance of the (R3) Left Curtain Squib 1 Line 1 circuit between the Left Side Curtain Airbag connector cavity 2 and the 8443-25 Adaptor cavity 32-6.

      Is the resistance below 1.0 ohm?

      Yes 

      • Go to step  4

      No 

  4. CHECK (R1) LEFT CURTAIN SQUIB 1 LINE 2 CIRCUIT FOR AN OPEN 
    Fig 3: Checking Left Curtain Squib 1 Line 2 Circuit

    1. Measure the resistance of the (R1) Left Curtain Squib 1 Line 2 circuit between the Left Side Curtain Airbag connector cavity 1 and the ORC 8443-25 Adaptor cavity 5.

      Is the resistance below 1.0 ohm?

      Yes 

        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.
        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 ORC in accordance with Service Information.
      • Perform AIRBAG SYSTEM VERIFICATION TEST .

      No 

  5. CHECKING STORED OR INTERMITTENT CODES 
    NOTE: Diagnose and repair all active codes before diagnosing stored codes.
    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.
    4. With the scan tool, monitor for active codes while performing the following:
      • 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 

      • Select the appropriate diagnostic procedure.

      No 

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