Diagnostic Intermittent Test
- RECORD AND ERASE ALL RESTRAINT SYSTEM DTCS
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. Disconnect components and inspect the harness and connectors for damage. Reconnect components and ensure they are properly seated. If equipped with the keyless ignition, use this ignition on warning. If equipped with the standard key ignition, use this ignition on warning. Turn the ignition off. Perform 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 (RESTRAINTS SYSTEM VERIFICATION TEST ) or refer to DIAGNOSTIC CODE INDEX for the appropriate diagnostic procedure.
No

If equipped with the standard key ignition, use this ignition on warning. Turn the ignition off. Perform any Technical Service Bulletins (TSBs) that may apply.
- ATTEMPT TO REPRODUCE THE CONDITION
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.
WARNING:Turn the ignition off, disconnect the battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury.
- 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. If equipped with the keyless ignition, use this ignition on warning. If equipped with the standard key ignition, use this ignition on warning. If numerous trouble codes were set, use a schematic and inspect any common ground or supply circuits.
