OEM 2008 Toyota Sequoia Air Bag

2008 Toyota Sequoia Parts Questions & Experts Answers

• Q: What are the key considerations for servicing the Air Bag system on 2008 Toyota Sequoia?

  A: The Supplemental Restraint System (SRS) of the vehicle comprises a steering pad together with front passenger Air Bag, curtain shield Air Bag, front seat side Air Bag and seat belt pretensioner alongside center Air Bag sensor, front Air Bag sensor, side Air Bag sensor, rear Air Bag sensor, occupant classification ECU and seat position Air Bag sensor. Any service procedure should begin only after a minimum 90-second period has passed since turning off the ignition switch and negative (-) terminal battery disconnection. The occupant classification ECU initialization procedure must be executed when any of these conditions occur: ECU replacement, accessory installation, passenger seat removal or reinstallation, an unoccupied seat indicator shows OFF or vehicle post-accident repairs. Verify DTCs before removing the negative terminal and inspect all SRS components after small impacts while avoiding the use of parts from different vehicles. A replacement should be made with a new SRS component whenever there is part drop or failure to meet specifications is observed. High impedance (minimum 10 kOhms/V) ohmmeters or voltmeters must be used for electrical circuit analysis of components which require following all cautions on attached information labels. Performance of SRS work must be followed by conducting SRS warning light examinations. Note down the memory settings of each system before removing the negative (-) battery terminal then restore them back after completing tasks. Waiting 90 seconds after disconnecting the negative (-) battery terminal is necessary before installing new Air Bag sensors or adjusting the doors on the vehicle. Air Bag sensors must remain undropped and undisturbed during operations. Thorough testing for DTCs should be initiated through SRS warning light assessment for any non-deployed Air Bags because Air Bag sensor replacements are required after deployment confirmation procedures. Yellow SRS connectors proved their high reliability through specific features that stop erroneous connections from taking place. To disconnect any connectors of the steering pad and front passenger Air Bag and curtain shield Air Bag and front seat outer belt you must push and hold the lock button while lifting the connector itself. The connector requires sufficient downward pressure to either create a clicking sound or until it reaches a locked position. The procedures for connecting the spiral cable and front seat side Air Bag and center Air Bag sensor connectors must be done exactly the same way by following proper locking procedures. Before coupling the front Air Bag sensor ensure that you check the housing lock position and press all connectors until you hear a click. The procedure for detached side Air Bag and rear Air Bag sensors includes slidable sleeve detachment followed by returning the sleeve to its original placement before reconnecting.
