CHECK FOR OPEN SQUIB CIRCUITS IN LEFT THORAX SEAT 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 Seat Thorax Airbag connector.
  WARNING:
  Do not place an intact undeployed 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 the connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool and the SRS Load Jumper to the Left Seat Thorax Airbag connector. (special tool #8443A, SRS Load Tool) (special tool #8443-8, Jumper, SRS Load)
  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: B274C-13-LEFT SIDE THORAX SQUIB 1-CIRCUIT OPEN?
  
  Yes
  - Go To 3
  No
  
  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.
