Diagnostic Test

CHECK FOR TECHNICAL SERVICE BULLETINS (TSB)
1. If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.
2. Review the Technical Service Bulletins (TSBs) related to the reported symptoms.

  Yes
  - Perform the appropriate TSB procedure.
  - Perform the AIRBAG SYSTEM VERIFICATION TEST. Refer to Standard Procedure .
  No
  - Go To 2.
RECORD AND ERASE ALL RESTRAINT SYSTEM DTCS
1. With the scan tool, record and erase all DTCs from the Occupant Restraint Controller (ORC). Monitor for any active codes as you work through the following steps.
2. Review the code monitored and set conditions for any DTCs that are stored and attempt to reproduce the conditions listed.
  - Wiggle the wiring harness and connectors of the related airbag circuit, sensor, or component.
  - If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
3. Turn the ignition off, wait five seconds, turn the ignition on.
4. Wait one minute, and read active codes, if there are none present, read the stored codes.

4. Wait one minute, and read active codes, if there are none present, read the stored codes.
5. If numerous trouble codes were set, use a schematic and inspect any common ground or supply circuits.
