Srscm (Restraints - Depowered): Overview Kia Forte I

Description

The primary purpose of the SRSCM (Supplemental Restraints System Control Module) is to discriminate between an event that warrants restraint system deployment and an event that does not. The SRSCM must decide whether to deploy the restraint system or not. After determining that pretensioners and/or airbag deployment is required, the SRSCM must supply sufficient power to the pretensioners and airbag igniters to initiate deployment.

The SRSCM determines that an impact may require deployment of the pretensioners and airbags from data obtained from impact sensors and other components in conjunction with a safing function.

The SRSCM will not be ready to detect a crash or to activate the restraint system devices until the signals in the SRSCM circuitry stabilize.

It is possible that the SRSCM could activate the safety restraint devices in approximately 2 seconds but is guaranteed to fully function after prove-out is completed.

The SRSCM must perform a diagnostic routine and light a system readiness indicator at key-on. The system must perform a continuous diagnostic routine and provide fault annunciation through a warning lamp indicator in the event of fault detection. A serial diagnostic communication interface will be used to facilitate servicing of the restraint control system.

1. Remove the ignition key from the vehicle.
2. Disconnect the battery negative cable and wait for at least three minutes before beginning work.
3. Disconnect the DAB, PAB, SAB, CAB and BPT connectors.
4. Remove the floor console. (For Coupe, refer to «CONSOLE»(ref-362224-S29666035482010060400000) . For Sedan, refer to «CONSOLE»(ref-362245-S31568523972010060400000) .)
5. Press the lock (1), the pull back the connector lever (2) until it clicks.
6. Disconnect the SRSCM harness connectors (A) and (B) from the SRSCM.
7. Remove the SRSCM mounting bolts (3EA) from the SRSCM, then remove the SRSCM.

Scheme 52

1. Remove the ignition key from the vehicle.
2. Disconnect the battery negative cable and wait for at least three minutes before beginning work.
3. Install the SRSCM with the SRSCM mounting bolts. Tightening torque (SRSCM Mounting Bolt) : 9.5 ~ 13.6 Nm (1.0 ~ 1.4 kgf.m, 7.2 ~ 10.1 lb.ft) NOTE: Use new mounting bolts when replacing the SRSCM after a collision.
4. Connect the SRSCM harness connectors.
5. Install the floor console. (For Coupe, refer to «CONSOLE»(ref-362224-S29666035482010060400000) . For Sedan, refer to «CONSOLE»(ref-362245-S31568523972010060400000) .)
6. Connect the DAB, PAB, SAB, CAB and BPT connectors.
7. Reconnect the battery negative cable.
8. After installing the SRSCM, 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.

The front impact sensor (FIS) is installed in the side member. It is a remote sensor that detect acceleration due to a collision at its mounting location. The primary purpose of the Front Impact Sensor (FIS) is to provide an indication of a collision. The Front Impact Sensor (FIS) sends acceleration data to the SRSCM.

Scheme 53

The Side Impact Sensor (SIS) system consists of two front SIS which are installed inside the Center Pillar (LH and RH). They are remote sensors that detect acceleration due to collision at their mounting locations. The primary purpose of the Side Impact Sensor (SIS) is to provide an indication of a collision. The Side Impact Sensor (SIS) sends acceleration data to the SRSCM.

Scheme 55

1. Disconnect the battery negative cable and wait for at least three minutes before beginning work.
2. Remove the door scuff trim. (For Coupe, refer to «INTERIOR TRIM»(ref-362224-S13627888552010060400000) . For Sedan, refer to «INTERIOR TRIM»(ref-362245-S31070305242010060400000) .)
3. Remove the center pillar trim. (For Coupe, refer to «INTERIOR TRIM»(ref-362224-S13627888552010060400000) . For Sedan, refer to «INTERIOR TRIM»(ref-362245-S31070305242010060400000) .)
4. Disconnect the side impact sensor connector.
5. Loosen the side impact sensor mounting bolt and remove the side impact sensor.
