Seat Position Sensor: Installation

1. Check that the engine switch is off.
2. Check that the cable is disconnected from the battery negative (-) terminal.
   CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
   NOTE:

   • w/ Navigation System:

     After the engine switch is turned off, the HDD navigation system requires approximately 6 minutes to record various types of memory and settings. As a result, after turning the engine switch off, wait 6 minutes or more before disconnecting the cable from the negative (-) battery terminal.

   • When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See INITIALIZATION ).
3. Using a 1.0 mm (0.0393 in.) feeler gauge, install the seat position sensor.
   NOTE:

   • If the seat position sensor has been dropped, or there are any cracks, dents or other defects in the case or connector, replace the seat position sensor with a new one.
   • When installing the seat position sensor, be careful that the SRS wiring does not interfere with other parts and that it is not pinched between other parts.

     Be sure that the clearance between the seat position sensor and the seat rail is within 0.6 to 1 4 mm (0 0236 to 0.0551 in.).

4. Using a T30 "TORX" socket wrench, install the seat position sensor with the screw.

   Torque: 8.0 N*m (82 kgf*cm, 71 in.*lbf) 

5. Make sure that the clearance between the seat position sensor and the seat rail is within 0.6 to 1 4 mm (0.0236 to 0.0551 in.).
6. Check that there is no looseness in the installation parts of the seat position sensor.
7. Connect the connector.
8. Install the seat slide position sensor protector to the seat position sensor.

1. Install the front seat assembly LH (See INSTALLATION ).
