Kia Rio: SRSCM / Side Impact Sensor (SIS)

Kia Rio 2017-2024 YB Service Manual / Restraint / SRSCM / Side Impact Sensor (SIS)

Description and operation

Description

•	Side Impact Sensor (SIS) system consists of two Pressure Side Impact Sensor (P-SIS) which are installed at each center of the front door module (LH and RH).

•	Pressure Side Impact Sensor is also called P-SIS because it detects pressure due to collision at its mounting location.

•	Side Impact Sensor is also called A-SIS because it detects acceleration.

•	SRSCM decides deployment of the airbag and the time of deployment through the collision signal of the SIS when the collision occurred.

Components and components location

Components

1. Pressure side impact sensor (P-SIS)

2. Front Gravity Side Impact Sensor (G-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 - "Front Door Trim")

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

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

Front Gravity side impact sensor (G-SIS)

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

2.	Remove the center pillar trim. (Refer to Body - "Center Pillar Trim")

3.	After disconnecting the side impact sensor connector (A) and loosening the bolt(B), remove the sensor.

Installation

Pressure side impact sensor (P-SIS)

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

Install a pressure side impact sensor screws.

Tightning torque :

3.0 - 4.0 N.m (0.3 - 0.4 kgf.m, 2.2 - 2.9 lb-ft)

3.	Connect the pressure side impact sensor.

4.	Install the front door trim. (Refer to Body - "Front Door Trim")

5.	Reconnect the battery negative terminal.

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

Connect the side impact sensor connector (A) and then tighten the bolt (B).

Tightening torque :

3.0 - 4.0 N.m (0.8 -10.4 kgf.m, 2.2 - 2.9 lb-ft)

3.	Install the front door trim. (Refer to Body - "Front Door Trim")

4.	Reconnect the battery negative terminal.

5.	After installing the 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.
