NOTE: The scan tool, SRS Load Tool Kit 8443A, and DVOM are required to perform the following test.
1. Select Active or Stored DTC.
  Is the DTC active or stored?
  
  ORC - ACTIVE DTC
  - Go to step 2
  ORC - STORED DTC
  - Perform the RESTRAINTS SYSTEM INTERMITTENT TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

  NOTE: Check connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-1 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 step 3
  No
  - Replace the Left Side Curtain Airbag in accordance with the Service Information.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
