Q: How to Remove the Air Bag Sensor Safely on 2009 Toyota Highlander?
A: The process of taking out the rear Air Bag sensor begins with reading all bulletin safety instructions before moving toward service. Place the cable over the negative battery terminal then wait for at least 90 seconds to avoid deploying Air Bags before reconnecting the cable. After the reconnection some systems require system initialization. Start by taking out the rear door scuff plate before removing the rear door opening trim Weather Strip and stripping the deck board assembly then proceeding to take off the No. 3 deck board sub-assembly as well as the No. 2 deck board sub-assembly and the tonneau cover assembly (if equipped), the rear No. 1 floor board (without rear No. 2 seat) together with the rear seat side cover LH (if equipped) and the deck side trim box LH. Continue by removing the rear seat side cover RH (if equipped), jack carrier support, jack carrier cushion, jack assembly, jack carrier assembly, deck side trim box RH, rear mat, deck floor board assembly (without rear No. 2 seat), deck floor board assembly (with rear No. 2 seat), rear deck floor box (without rear No. 2 seat), No. 1 deck board (without rear No. 2 seat), No. 1 deck board (with rear No. 2 seat), rear No. 2 seat inner belt assembly (if equipped), and disconnecting the rear seat lap type belt assembly LH and RH (if equipped). Remove the rear No. 2 seat assembly (if equipped), rear floor finish plate, rear seat side garnish cap (for RH side without rear air conditioning system), rear seat side garnish cap (for RH side with rear air conditioning system), deck side trim cover, deck side trim, side trim cover LH (for LH side without rear seat entertainment system), power outlet socket bezel (for LH side with rear seat entertainment system), side trim cover RH (for RH side without rear automatic air conditioning system), rear room temperature sensor (for RH side with rear automatic air conditioning system), rear combination light service cover LH (for LH side), rear combination light service cover RH (for RH side), rear power point socket assembly (for LH side), rear power outlet socket cover (for LH side), rear deck trim cover (for LH side without remote folding function), reclining remote control bezel (for LH side with remote folding function), rope hook assembly, No. 2 deck side trim hook (for LH side), No. 1 luggage compartment trim hook (for RH side), front deck side trim cover, disconnect the rear No. 1 seat outer belt assembly, remove the deck trim side panel assembly LH (for LH side), and remove the deck trim side panel assembly RH (for RH side). Follow by disconnecting the connector from the rear Air Bag sensor while paying attention to avoid harming the Air Bag wire harness before removing the bolt to disengage the pin that extracts the rear Air Bag sensor which requires holding the sensor throughout the bolt removal process to prevent stopping the sensor pin from breaking.
