Rear Airbag Sensor: Installation

WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.

INSTALL REAR AIRBAG SENSOR
1. Check that the engine switch is off
2. Check that the cable is disconnected from the negative (-) battery terminal.
  CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
3. Install the rear airbag sensor with the bolt and pin
  Torque: 9.0 N*m (92 kgf*cm, 80 in.*lbf)
  NOTE:
  - If the rear airbag sensor has been dropped, or there are any cracks, dents or other defects in the case or connector, replace it with a new one.
  - When installing the rear airbag sensor, be careful that the SRS wiring does not interfere with other parts and that it is not pinched between other parts.
  - Make sure that the pin is securely inserted into the body hole.
  - Tighten the bolt while holding the rear airbag sensor because the rear airbag sensor pin (stopper) is easily damaged.
