2007 Toyota Highlander Parts Questions & Experts Answers

• Q: How does the Air Bag Supplemental Restraint System (SRS) function and what precautions should be taken during servicing on 2007 Toyota Highlander?

  A: Service operations must be performed with great precision to avoid surprising SRS deployments or failures because the vehicle comes with a Supplemental Restraint System (SRS) consisting of driver Air Bag and front passenger Air Bag with front side Air Bag and curtain shield Air Bag and front seat belt pretensioner. A minimum of 90 seconds should pass between switching off the ignition and removing the negative battery terminal cable since the SRS maintains a power reserve. The hot air and flame exposure must be always avoided for all SRS elements including steering pad components along with Air Bag assemblies, sensors, seat belt assemblies, and steering pad assemblies. Preventive checks of DTCs should always be performed before removing the battery while manufacturers require component inspections after collisions regardless of whether Air Bags activate. Measures need to be taken to remove the Air Bag sensor before all repair operations that could apply external stress followed by immediate replacement with new SRS parts instead of attempting to reuse or repair damaged components. The correct testing tool for SRS components has to be a high impedance volt/ohmmeter with resistance exceeding 10 kohms/V while technicians need to observe all safety markings in the area. Clear the system memory through negative (-) terminal cable removal only after you conduct warning light checks and record system memories. The process of returning power to the system requires the sensors from the center Air Bag assembly and the two front sensors and the side sensors and rear sensors on each side to be initialized. The repair process requires waiting 90 seconds after disconnecting the negative (-) terminal cable to handle Air Bag sensors properly with correct installation of sensors and the avoidance of using dropped sensors. Secure the SRS connectors with a yellow color coding by implementing the terminal twin-lock mechanism along with activation prevention mechanism and electrical connection check mechanism and half connection prevention mechanism while using the connector lock mechanism. The procedure to separate connectors from the steering pad requires unlocking the button before lifting the connector carefully. This process includes disconnecting the front passenger Air Bag assembly and driver side knee Air Bag assembly and curtain shield Air Bag assembly and front seat outer belt assembly. The reconnection process requires pushing down the connector all the way until it produces an audible click. Users should disconnect the front seat side Air Bag assembly connector by sliding its lock before reconnecting it properly and verifying that the slider clicks into its original location. To disconnect and reconnect the front Air Bag sensor with its counterpart and the side and rear Air Bag sensors use the outer locking sleeve to slide it away from the sensor before restoring the outer to its initial position after a click has been achieved.
