Kia Soul EV (PS EV) 2015-2020 Service Manual / Restraint / SRSCM / SRS Control Module (SRSCM) Description and Operation

Description
The primary purpose of the SRSCM (Supplemental Restraints System Control Module) is to determine an event that warrants restraint system air bag deployment. 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 whether or not an impact requires deployment of pretensioners and/or airbags based on data obtained from impact sensors and other components in conjunction with safety function.
The SRSCM will not be ready to detect a crash event or to activate the restraint system devices until the signals in the SRSCM circuitry are stabilized.
While it is possible that the SRSCM can activate the safety restraint devices, it is guaranteed to fully function after completing validation.
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.
The yaw and G sensors which are used in ESC are located inside the SRSCM. The sensor signal is sent by a separate CAN signal between the ESC control module and SRSCM.
