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 Right Side Curtain Airbag connector.
  WARNING: Do not place an intact uncoupled curtain 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 SRS Load Tool Kit 8443A and the SRS Load Tool Jumper 8443-8 to the Right 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: B1B22-RIGHT SIDE CURTAIN SQUIB 1 CIRCUIT OPEN?
  
  Yes
  - Go To 3
  No
  - Replace the Right Side Curtain Airbag in accordance with the Service Information.
  - Perform the ORC VERIFICATION TEST. See DTC-Based Diagnostics/CONTROLLER, Occupant Restraint (ORC) - Standard Procedure .

  NOTE: Check the connectors - Clean and repair as necessary.
3. Connect the SRS Load Tool Kit 8443A and SRS Load Tool Adaptor 8443-24 to the ORC C1 connector.
4. Measure the resistance of the (R4) Right Curtain Squib 1 Line 1 circuit between the Right Side Curtain Airbag connector and the SRS Load Tool Adaptor 8443-24.
5. Measure the resistance of the (R2) Right Curtain Squib 1 Line 2 circuit between the Right Side Curtain Airbag connector and the SRS Load Tool Adaptor 8443-24.
  Is the resistance below 1.0 Ohm?
  
  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 (R4) Right Curtain Squib 1 Line 1 circuit or the (R2) Right Curtain Squib 1 Line 2 circuit for an open.
