Diagnostic Test

DETERMINE ACTIVE OR STORED DTC
NOTE: Make sure 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.
  NOTE: Check the connectors - Clean and repair as necessary.
2. Connect the SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-14 to the Passenger Airbag Squib 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: 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 ORC VERIFICATION 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 SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-14 from the Passenger Airbag Squib connector.
2. Disconnect the ORC connectors.
  NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Adaptor 8443-24 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 SRS Load Tool Adaptor 8443-24.
5. Measure the resistance of the (R44) Passenger Squib 1 Line 1 circuit between the Passenger Airbag Squib connector and the SRS Load Tool Adaptor 8443-24.
  Is the resistance below 1.0 Ohm for both circuits?
  
  Yes
  - Replace the ORC in accordance with the Service Information.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
  No
  - Repair the (R42) Passenger Squib 1 Line 2 circuit or (R44) Passenger Squib 1 Line 1 circuit for an open.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .
