Diagnostic 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.WARNING:
Maintain a safe distance from all airbags while performing the following steps. Failure to follow these instructions may result in possible serious or fatal injury.
WARNING:On vehicles equipped with the high voltage system, disconnecting the 12-volt battery negative cable alone will not power down the 12-volt system. You must perform the 12-volt Power Down procedure before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. Refer to STANDARD PROCEDURE .
- 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.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 codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
- 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, refer to RESTRAINTS SYSTEM VERIFICATION TEST , or for the appropriate diagnostic procedure, refer to the DIAGNOSTIC CODE INDEX .
No
- Go To 2
- Review the code monitored and set conditions for any DTCs that are stored and attempt to reproduce the conditions listed.
- 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.
- 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.WARNING:
Turn the ignition on, then reconnect the 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 PROCEDURE. Refer to RESTRAINTS SYSTEM VERIFICATION TEST .
No
- The problem cannot be found at this time.
- 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.
