Kia Rio: SRS Control Module (SRSCM) Description
The primary purpose of the Supplemental Restraints System Control Module
(SRSCM) 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.
