Kia Sportage: SRSCM / SRS Control Module (SRSCM) Description and operation
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.
