  NOTE:
  The IP Harness is always connected to the right side (C1) of the SRS Load Tool Adaptor (special tool #8443-32-L, Adapter, SRS Adapter).
4. Measure the resistance between the (R505) Driver Seat Belt Retractor Tensioner Line 1 circuit cavity C2-1 and the (R503) Driver Seat Belt Retractor Tensioner Line 2 circuit cavity C2-2 at the SRS Load Tool Adaptor (special tool #8443-32-L, Adapter, SRS Adapter).
  Is the resistance below 10K Ohms?
  
  Yes
  - Repair the (R505) Driver Seat Belt Retractor Tensioner Line 1 circuit for a short to the (R503) Driver Seat Belt Retractor Tensioner 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.

STORED ORC DTC
1. With the scan tool, record and erase all DTC from all Airbag System Modules.
2. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
  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.
3. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
4. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
5. The following additional checks may assist you in identifying a possible intermittent problem.
6. Reconnect any disconnected components and harness 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.
7. With the scan tool monitor active codes as you work through the following steps.
8. Wiggle the wiring harness and connectors of the related airbag circuit or component.
9. If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
10. If only stored codes return continue the test until the problem area has been isolated.
11. In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.
  Are any ACTIVE DTC present?
  
  Yes
  - Refer to the DIAGNOSTIC CODE INDEX article and perform the appropriate diagnostic procedure.
  No
  - No problem found at this time. Erase all codes before returning vehicle to customer.
