How Should Air Bags Be Properly Armed and Disarmed During Service and Repair on 2009 Scion xB?

Question

Accepted Answer

The vehicle contains Supplemental Restraint System (SRS) Air Bags alongside sensors so service procedures must be followed properly to avoid dangerous injuries from unexpected deployments. Wait for at least 90 seconds from when the ignition switch turns to OFF and you remove the negative battery terminal because SRS components contain a reserve power supply. It is essential to initialize the ECU whenever occupancy sensors show an Air Bag-off problem or the replacement or installation of accessories occurs or when a vehicle experiences an accident or the occupant seat is moved between different places. The symptom detection of SRS part malfunctions requires DTC checks as the symptoms are difficult to confirm directly before disconnecting the negative (-) battery terminal. A thorough inspection of SRS components follows all minor automobile accidents before removing any Air Bag sensors that might risk exposure to additional fixes. Replacement of active SRS components requires fresh parts only and must never involve repairs or deconstruction from alternative vehicles or distribution of components. The use of an ohmmeter/voltmeter with high impedance at 10 kOhms/V minimum is required for electrical troubleshooting tasks while following all warnings on information labels should be done. It is essential to verify the SRS warning light once you finish working on the system. A memory reset occurs when disconnecting the negative (-) battery terminal thus technicians need to document original settings before work begins followed by resetting after completing the operation. The installation period for Air Bag sensor handling requires waiting 90 seconds after disconnecting the negative (-) terminal before working on sensors or making door adjustments. The installation of all sensors must occur before connector attachment or detachment while using only sensors which have not been dropped. Vehicle accident analysis should include DTC checking when Air Bags fail to deploy as well as new sensor installation if Air Bags have deployed. The yellow SRS connectors deliver high reliability through hardware designed for secure connection prevention. Correct procedures exist for disconnecting then connecting connectors on steering pad, front passenger Air Bag, curtain shield Air Bag, front seat outer belt, spiral cable, front seat side Air Bag, and center Air Bag sensor wiring which requires both secure attachments and verification of proper click noises.
