SRS Control Module (SRSCM) ➤

Front Impact Sensor (FIS)

- Description

• The front impact sensors (FIS) are installed on the upper of the side panel in Front End Module (FEM). They are remote sensors that detect acceleration due to a collision at their mounting locations.

• The primary purpose of the Front Impact Sensor (FIS) is to provide an indication of a collition. The Front Impact Sensor (FIS) sends acceleration data to the SRSCM.

1. Front right Impact Sensor (FIS)
2. Front left Impact Sensor (FIS)

• Removal of the airbag must be performed according to the precautions/ procedures described previously.

• Before disconnecting the front impact sensor connector, disconnect the front airbag connector(s).

• Do not turn the ignition switch ON and do not connect the battery cable while replacing the front impact sensor.

1.Disconnect the battery negative cable, and wait for at least three minutes before beginning work.

2.Disconnect the front impact sensor connector (A).

3.Remove the front impact sensor (A) after loosening the mounting bolt.

• Do not turn the ignition switch ON and do not contact the battery cable while replacing the front impact sensor.

1.Install the new front impact sensor.

2.Connect the front impact sensor connector.

3.Install the front impact sensor mounting bolt.

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

4.Reconnect the battery negative cable.

5.After installing the Front 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.

Side Impact Sensor (SIS)

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

1. Side Impact Sensor (SIS)

1.Disconnect the battery negative cable and wait for at least three minutes before beginning work.

2.Remove the door scuff trim. (Refer to the Body group - "Interior trim")

3.Remove the center pillar trim. (Refer to the Body group - "Interior trim")

4.Loosen the side impact sensor mounting bolt (A) and remove the side impact sensor.

• Do not turn the ignition switch ON and do not connect the battery cable while replacing the side impact sensor.

1. Install the new side impact sensor with the bolt (A) then connect the side impact sensor connector.

Tightening torque : 7.0 - 9.0 N.m (0.71 - 0.92 kgf.m, 5.2 - 6.6 lb-ft)

2.Install the center pillar trim.(Refer to Body - "Interior tirm")

3.Install the door scuff trim. (Refer to Body - "Interior tirm")

4.Reconnect the battery negative cable.

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.
