Diagnostic Test

  1. 1)  DETERMINE ACTIVE OR STORED DTC 
    NOTE: Ensure that the battery is fully charged.
    NOTE: The scan tool, SRS Airbag Load Tool MRL 8443, and DVOM are required to perform the following test.

    Turn the ignition on.

    Select ACTIVE or STORED DTC: 

    ACTIVE DTC 

    1. Go To step  2).

    STORED DTC 

    1. Go To step  5).
  2. 2)  CHECK FOR OPEN SQUIB CIRCUITS IN RIGHT SEAT AIRBAG

    NOTE: Check connectors - Clean and repair as necessary.

    Connect the 8443 Load Tool and appropriate Jumper to the Right Seat Airbag connector.

    WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

    With the scan tool, read the active ORC DTCs.

    Does the scan tool display: BIB22-RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT OPEN? 

    Yes 

    1. Go to step  3).

    No 

    1. Replace the Right Seat Airbag in accordance with the Service Information.
    2. Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1 .

    Disconnect the ORC connectors.

    NOTE: Check connectors - Clean and repair as necessary.

    Connect the 8443 Load Tool ORC Adaptor to the ORC C1 connector.

    Measure the resistance of the (R4) Right Seat Squib 1 Line 2 circuit between the Right Seat Airbag connector and the 8443 ORC Adaptor.

    Is the resistance below 1.0 ohm? 

    Yes 

    1. Go To step  4).

    No 

    1. Repair the (R4) Right Seat Squib 1 Line 1 circuit for an open.
    2. Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1 .
  4. 4)  CHECK (R2) RIGHT CURTAIN SQUIB 1 LINE 2 CIRCUIT FOR AN OPEN 
    Fig 3: CHECKING RIGHT CURTAIN SQUIB 1 CIRCUIT

    Measure the resistance of the (R2) Right Seat Squib 1 Line 2 circuit between the Right Seat Airbag connector and the 8443 ORC Adaptor.

    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 take the proper precautions can result in accidental airbag deployment and personal injury or death.
    WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

    2. Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1 .

    No 

    1. Repair the (R2) Right Seat Squib 1 Line 1 circuit for an open.
    2. Perform *AIRBAG SYSTEM VERIFICATION TEST - VER 1.
  5. 5)  CHECKING STORED OR INTERMITTENT CODES 
    NOTE: Diagnose and repair all active codes before diagnosing stored codes. Refer to the DIAGNOSTIC CODE INDEX table for a complete list of airbag system diagnostic procedures.

    With the scan tool, record and erase all Airbag System Module DTCs.

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

    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.

    Reconnect all disconnected components and harness connectors.

    WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

    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.

    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 

    1. Select the appropriate diagnostic procedure from the DIAGNOSTIC CODE INDEX table.

    No 

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