      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 #8443-1, Jumpers, 2 Pin) to the Driver Airbag Squib 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.

    3. With the scan tool, read the active ORC DTCs.

      Does the scan tool display: B1B00-DRIVER AIRBAG SQUIB 1 CIRCUIT LOW?

      Yes 

      • Go To  3

      No 

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

      • Go To  4

      No 

      • Replace the Clockspring connector in accordance with the Service Information.
      • Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
