Diagnostic Test

With the scan tool, record and erase all DTCs from all restraints system modules. Monitor for any active codes as you work through the following steps.

• 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.
• Turn the ignition off.
• Refer to any Technical Service Bulletins (TSBs) that may apply.

Was the source of the customer complaint found or did any DTCs appear and stay active?

Yes 

• Make the appropriate repairs and either perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to Standard Procedure .
• Select the DTC procedure from the appropriate Diagnostic Information. Refer to Diagnosis and Testing .

No 

• Go To  2.

In the event the customer complaint cannot be duplicated due to an intermittent condition in the restraints system, the following may aid in attempting to reproduce the condition.

• Using the wiring diagram/schematic as a guide, inspect the wiring and connectors related to the stored code or component in question.
• Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
• Reconnect any disconnected components and harness connectors and ensure they are properly seated.
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.

• If numerous trouble codes were set, use a schematic and inspect any common ground or supply circuits.

Was the source of the intermittent condition located?

Yes 

• Make the appropriate repairs and perform the RESTRAINTS SYSTEM VERIFICATION TEST. Refer to Standard Procedure .

No 

• The problem cannot be found at this time.
