1. With the scan tool, record and erase all Airbag System Module DTCs.
  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 chaffed, 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 DTCs present?
  
  Yes
  - Select the appropriate diagnostic procedur. Refer to OCCUPANT RESTRAINT CONTROLLER (ORC) - DIAGNOSTIC CODE INDEX
