2007 Toyota Corolla Parts Questions & Experts Answers

• Q: What precautions should be taken when servicing the air bag system equipped with a Supplemental Restraint System (SRS) on 2007 Toyota Corolla?

  A: To avoid unexpected Air Bag deployment or failure of the SRS system service operations need specific attention because the vehicle has a Supplemental Restraint System (SRS) that combines driver Air Bag and front passenger Air Bag and side Air Bag and curtain shield Air Bag and front seat belt pretensioner functions. The SRS Back Up power remains active for 90 seconds after ignition shutdown and battery terminal disconnection thus servicing should not begin immediately. The inspection of DTCs should occur before battery disconnection while SRS components must be kept free from both hot air exposure and open flame contact because DTC malfunction symptoms might prove hard to verify. A thorough check of all SRS components should be conducted even when the Air Bags remained deactivated after minor collision incidents. All maintenance operations on SRS parts require the removal of the Air Bag sensor followed by use of new SRS components and a prohibition against repairs of steering pad and front passenger Air Bag assembly and center Air Bag sensor assembly. To test electrical circuits properly use a high impedance (10 k Ohms/V minimum) volt/ohmmeter while you must verify SRS warning lamp function before finishing SRS-related work. Each system should be noted down with its stored information before starting work because disconnecting the negative cable (-) terminal will delete the memory. Replace or adjust Air Bag side-equipped door components only after waiting 90 seconds after taking off the negative (--) terminal cable. Use the proper technique to install Air Bag sensor connectors and avoid using any sensors which have been allowed to drop. You must inspect DTCs first if the Air Bags fail to activate during an accident followed by sensor replacement for any deployed Air Bags. Yellow marks indicate SRS connectors and each connector has safety mechanisms for proper connection together with dependable locking features. The process to disconnect Steering Pad connectors along with Curtain Shield Air Bag Assembly connectors and Front Seat Outer Belt Assembly connectors requires unlocking the button first before carefully lifting the connectors from their sockets. The Front Passenger Air Bag Assembly requires the slider to be used for unlock before connection separation while the Front Seat Side Air Bag Assembly also needs slider usage for unlock before disconnect. Before connection complete the attachment securely and verify a clicking sound occurs. The process of connecting the Center Air Bag Sensor Assembly involves securely pushing the lever after placing the holder with connectors inside. Maintain pressure on the lever until it secures into position. Users should disconnect the Front Air Bag Sensor and Side Air Bag Sensor and Rear Air Bag Sensor using their fingers on the outer connector locking sleeve to slide apart and verify strong reconnection afterwards.
