DESCRIPTION
ECCF71AB
The primary purpose of the SRSCM (Supplemental
Restraints System Control Module) is to discriminate be-
tween 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 de-
termining 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 communi-
cation interface will be used to facilitate servicing of the
restraint control system.
