2007 Toyota 4Runner Air Bag Parts Q&A

• Q: What are the essential precautions and procedures for servicing an Air Bag system on 2007 Toyota 4Runner?

  A: Service operations must follow strict procedures to stop unexpected SRS deployment or failure because the vehicle contains a Supplemental Restraint System (SRS) with driver Air Bag and front passenger Air Bag and side Air Bag and curtain shield Air Bag and front seat belt pretensioner. The vehicle requires waiting for at least 90 seconds after moving the ignition switch to "LOCK" and removing the battery's negative (-) terminal cable due to the SRS's built-in emergency power supply. Checking DTCs before cutting the battery connection is vital because diagnosing malfunction symptoms requires care due to their indistinct nature. Hot air treatments must stay away from SRS components and workers should check all components before battery removal. Consult the repair guidelines for minor collisions because you need to evaluate each important part especially the steering pad and front passenger Air Bag assembly sensor and their listed parts and should remove the Air Bag sensor before starting the repair when possible shock happens. The system requires new SRS components while it prohibits critical component disassembling or repairs and demands the use of a suitable volt/ohmmeter with minimum 10 kohms/V impedance for electrical troubleshooting. When the SRS work ends the technician should examine warning lights and document system memory readouts then disconnect the battery and forget all recorded information. Replace sensors and adjust side Air Bags in doors after you wait at least 90 seconds from when you remove the negative terminal. Prevent dropping or disassembling Air Bag sensors while also checking the DTCs for Air Bags which did not deploy. The yellow-colored SRS connectors use special mechanisms to hold the connections securely and avoid unintentional separation. The process to disconnect steering pad, curtain shield Air Bag assembly and front seat outer belt assembly connectors includes releasing the lock button followed by lifting the connector. Prior to disconnecting the front passenger Air Bag assembly and front seat side Air Bag assembly, users need to move the slider to unlock the mechanism. To ensure a secure connection when reattaching lock buttons must click entirely into position and you should keep front Air Bag sensors locked by holding the outer sleeve before sliding.
