Hyundai Sonata: SRSCM / SRS Control Module (SRSCM) Description and Operation
Hyundai Sonata LF 2014-2019 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 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.
