    1. Turn the ignition on.

      Select ACTIVE or STORED DTC:

      ACTIVE DTC 

      • Go To  2

      STORED DTC 

  2. CHECK FOR OPEN SQUIB CIRCUITS IN THE 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 SRS Load Tool Kit (special tool #8443A, SRS Load Tool) and SRS Load Tool Jumper (special tool #8443-8, Jumper, SRS Load) 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  3

      No 

      • Replace the Left Side Curtain Airbag in accordance with the Service Information.
      • Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .

    3. Connect the SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) 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 SRS Load Tool Adaptor (special tool #8443-25, 56 Way ACM Adapter) cavity 32-9.

      Is the resistance below 1.0 Ohm?

      Yes 

      • Go To  4

      No 

      • Repair the (R3) Left Curtain Squib 1 Line 1 circuit for an open.

        Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
