RESTRAINTS SYSTEM INTERMITTENT TEST

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

1. 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. 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»(ref-457871-S26700628122012030200000) . Select the DTC procedure from the appropriate Diagnostic Information. Refer to «Diagnosis and Testing»(ref-457871-S00283187372012030200000) . No Go To 2 .
2. 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 12-volt 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 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»(ref-457871-S26700628122012030200000) . No The problem cannot be found at this time.

1. Before attempting to repair any restraint system, technicians should be familiar with and fully understand the system operation. Refer to Restraints System Description and Operation for complete details. Refer to «Operation»(ref-457806-S16005739082012030200000) . Refer to «Description»(ref-457806-S14336261192012030200000) . The following should be used as a checklist to be completed in its entirety prior to referencing specific Restraints Diagnostic Procedures. FOLLOW THE BASIC OUTLINE SET FORTH IN THE SIX-STEP TROUBLESHOOTING PROCEDURE Verification of complaint. Verification of any related symptoms. Symptom analysis. Problem isolation. Repair of isolated problem. Verification of proper operation. TAKE INTO ACCOUNT CURRENT VEHICLE CONDITION, REPAIR HISTORY, AND TECHNICAL SERVICE BULLETINS (TSBs) Verify that there are no outward signs of vehicle damage or effects from a collision that could impact the proper operation of the Restraints system. Check for aftermarket vehicle accessories that may have been installed improperly or could interfere with the system. Check the vehicle repair history for repairs that may relate to the current condition. Check for current Technical Service Bulletins (TSBs) for the Restraints system related to the customer concern. If a TSB applies, follow the procedure outlined in the TSB. DIAGNOSE ONLY THOSE FAILURES THAT ARE ACTIVE AND CAN BE REPRODUCED Check the control module central to the subsystem that is exhibiting the condition for active DTCs. For an intermittent failure that is not active at the time of vehicle inspection, perform the RESTRAINTS SYSTEM INTERMITTENT TEST and document the event on the repair order. Refer to «Standard Procedure»(ref-457871-S26700628122012030200000) . ADDRESS ACTIVE DIAGNOSTIC TROUBLE CODES (DTCs) IN THE CORRECT ORDER Low/High Voltage and Serial Data Loss of Communication Codes. Module Internal Failure and Configuration Mismatch Codes. Circuit specific DTC failures. Should the malfunction still be present after conducting this Pre-diagnostic Procedure, technicians should continue to the appropriate DTC procedure. Refer to «Diagnosis and Testing»(ref-457871-S00283187372012030200000) . Was the Pre-Test reviewed and is the DTC still present? Yes Perform the appropriate DTC procedure. Refer to «Diagnosis and Testing»(ref-457871-S00283187372012030200000) . No Test Complete.

1. PERFORM THE RESTRAINTS SYSTEM VERIFICATION TEST NOTE: If the ORC has been replaced, the ORC Initialization Procedure must be performed to clear the ORC Unlocked DTC and bring the module to a full state of readiness. Refer to the DTC list. Refer to «Diagnosis and Testing»(ref-457871-S00283187372012030200000) . Please perform all steps in the sequence presented following exactly the steps to successfully complete the procedures. 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. Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery. If equipped with the keyless ignition, use this ignition on warning. WARNING: Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. If equipped with the standard key ignition, use this ignition on warning. 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. Connect the scan tool to the Data Link Connector - use the most current software available. With the scan tool, erase stored DTCs in all airbag system modules. Perform module reset. NOTE: If equipped with an Airbag On - Off switch, read the DTCs in all switch positions. Exercise the Restraints System to duplicate the appropriate monitor conditions for any DTCs that were set. Wait one minute, and read active codes, if there are none present, read the stored codes. If the scan tool shows any active or stored codes, return to the DTC Index and follow the path specified for that trouble code. If no active or stored codes are present, the repair is complete. Are any DTCs present or, is the original condition still present? Yes Refer to «Diagnosis and Testing»(ref-457871-S00283187372012030200000) and perform the appropriate diagnostic procedure. No 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. If the battery was disconnected for any reason, you must perform the Battery Reconnection procedure in the 8F-Engine Systems article of the Service Information. NOTE: Please follow the ignition on warnings for either the standard key ignition or keyless ignition for reintroducing battery voltage to the restraint airbag system. WARNING: Disconnect the 12-volt battery wait two minutes before proceeding, remove the ORC fuses, connect the 12-volt battery, wait two minutes before proceeding. Cycle the ignition to the On position, then reconnect the ORC fuses. Wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. 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.
