      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 Right Side Curtain Airbag connector.

      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: B1B20-RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT LOW?

      Yes 

      • Go To  3

      No 

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

    5. Measure the resistance of the (R2) Right Curtain Squib 1 Line 2 circuit between SRS Load Tool Adapter (special tool #8443-25, 56 Way ACM Adapter) cavity 32-11 and ground.

      Is the resistance below 10k Ohms on either circuit?

      Yes 

      • Repair the Right Curtain Squib 1 circuits with resistance below 10k Ohms for a short to ground.
      • Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
