DETERMINE ACTIVE OR STORED DTC
NOTE: Ensure the battery is fully charged.

NOTE: The scan tool, SRS Airbag Load Tool MRL 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 .

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 Passenger Airbag Squib 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 connectors - Clean and repair as necessary.
2. Connect the 8443A Load Tool to the Passenger Airbag Squib connector.
  WARNING: Turn the ignition on, then reconnect the battery and wait two minutes to proceed. 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: B1B0A PASSENGER AIRBAG SQUIB 1 CIRCUIT OPEN?
  
  Yes
  - Go to step 3
  No
  - Replace the Passenger Airbag in accordance with the Service Information.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

2. Disconnect the ORC connectors.
  NOTE: Check connectors - Clean and repair as necessary.
3. Connect the 8443A Load Tool ORC Adaptor to the ORC C2 connector.
4. Measure the resistance of the (R42) Passenger Squib 1 Line 2 circuit between the Passenger Airbag Squib connector and the 8443A ORC Adaptor.
  Is the resistance below 1.0 ohm?
  
  Yes
  - Go to step 4
  No

1. Measure the resistance of the (R44) Passenger Squib 1 Line 1 circuit between the Passenger Airbag Squib connector and the 8443A ORC Adaptor.
  Is the resistance below 1.0 ohm?
  
  Yes
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure
    If DTC B1B0A-PASSENGER AIRBAG SQUIB 1 CIRCUIT OPEN is still active, replace the ORC in accordance with the Service Information and then Perform the RESTRAINTS SYSTEM VERIFICATION TEST.
  No
  - Repair the (R44) Passenger Squib 1 Line 1 circuit for an open.
  - Perform the RESTRAINTS SYSTEM VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
