Installation
Pressure Side Impact Sensor

Tightening torque :
7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)

   
Use the specified screws surely.

Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.
   
You must comply with the specified tightening torques with the tool specified because Pressure – Side Impact Sensors (P-SIS) may be broken or POP-NUT may be rotated.
Problems may be occurred in the durability of P-SIS or impact sensing performance may be depreciated if POP-NUT is rotated.
The door module must not be transformed because SRSCM judges a impact through the pressure sensor in the door module.
