Kia Niro: SRSCM / Side Impact Sensor (SIS) Repair procedures

Kia Niro 2017 (DE HEV) Service Manual / Restraint / SRSCM / Side Impact Sensor (SIS) Repair procedures

Removal

Pressure side impact sensor (P-SIS)

1.	Disconnect the battery negative terminal, and wait for at least thirty seconds before beginning work.

2.	Remove the front door trim. (Refer to Body (Interior and Exterior) - "Front Door Trim")

3.	Remove the pressure side impact sensor (A).

Loosen the side pressure sensor mounting screw, and remove the sensor (B).

Tightening torque:

2.0 - 3.0 N.m (0.2 - 0.3 kgf.m, 1.5 - 2.2 lb-ft)

Front Gravity side impact sensor (G-SIS)

1.	Disconnect the battery negative terminal, and wait for at least thirty seconds before beginning work.

2.	It separates the center pillar trim. (Refer to Body - see "built-in trim")

3.	Remove the side impact sensor connector (A).

Loosen the mounting bolts and remove the side impact sensor (B).

Tightening torque:

8.0 - 10.0 N.m (0.8 - 1.0 kgf.m, 5.9 - 7.3 lb-ft)

Installation

Pressure side impact sensor (P-SIS)

1.	Install in the reverse order of removal.

After replacing the side impact sensors must ensure that the system is operating normally.

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 the 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.

Front Gravity side impact sensor (G-SIS)

1.	Install in the reverse order of removal.

•	You must comply with the specified tightening torques with the tool specified because Pressure – Side Impact Sensors (P-SIS) may be broken or the 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.
