  NOTE:
  Check connectors - Clean and repair as necessary.
2. Connect the Load Tool (special tool #8443A, SRS Load Tool) and Jumper (special tool #8443-1, Jumpers, 2 Pin) to the Right Seat Squib 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 DTC.
  Does the scan tool display: B1C2E-RIGHT SIDE SEAT THORAX SQUIB 1 SHORTED TOGETHER?
  
  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.
  - Replace the Right Seat Squib Airbag in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to 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 Load Tool (special tool #8443A, SRS Load Tool) and Jumper (special tool #8443-1, Jumpers, 2 Pin) from the Right Seat Squib Airbag connector.
2. Disconnect the ORC connectors.
  NOTE:
  Check connectors - Clean and repair as necessary.
3. Connect the ORC Adaptor (special tool #8443-32-L, Adapter, SRS Adapter) to the ORC connectors.
4. Measure the resistance between the (R32) Right Seat Squib Line 1 circuit and the (R34) Right Seat Squib Line 2 circuit at the ORC Adaptor (special tool #8443-32-L, Adapter, SRS Adapter).
  Is the resistance below 10K Ohms?
  
  Yes
  - Repair the rue Right Seat Squib Line 1 circuit for a short to the (R34) Right Seat Squib Line 2 circuit.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  
  WARNING:
  If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to follow these instructions may result in possible serious or fatal injury.
  - Replace the Occupant Restraint Controller in accordance with the Service Information.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
CHECKING STORED OR INTERMITTENT CODES
NOTE:
Diagnose and repair all active codes before diagnosing stored codes. For a complete list of airbag system diagnostic procedures, refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX .
1. With the scan tool, record and erase all Airbag System Module DTC.
  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.
2. Using the wiring diagram/schematic as a guide, inspect the related wiring and connectors for chafed, pierced, pinched, and partially broken wires, and for broken, bent, pushed out, corroded, and contaminated terminals. Repair as necessary.
3. Reconnect all disconnected components and harness connectors.
  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.
4. With the scan tool, monitor for active codes while performing the following:
  - Wiggle the wiring harness and connectors of the related airbag circuit.
  - Continue the test until either a code becomes active or the problem area is isolated.
5. In the previous steps you have attempted to recreate the conditions responsible for setting the DTC in question/causing the intermittent condition.
  Are any ACTIVE DTC present?
  
  Yes
  - Refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX and perform the appropriate diagnostic procedure.
  No
  - No problem found at this time. Erase all codes before returning the vehicle to the customer.
