Installation

Pressure Side Impact Sensor

Install the new pressure side impact sensor with the screws then connect the pressure side impact sensor connector.

Tightening torque :

3.5 ~ 4.5 N.m (0.36 ~ 0.46 kgf.m, 2.6 ~ 3.3 lb-ft)

•	Use the specified screws.

2.	Install the front door trim. (Refer to the Body group- Front door)

After installing the pressure side impact sensor, confirm proper system operation:

•	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 occur in the durability of P-SIS or the impact sensing performance may depreciate if POP-NUT is rotated.

•	The door module must not be modified because SRSCM judges an impact through the pressure sensor in the door module.
