RESTRAINT SYSTEM
CONTROL MODULE
Supplemental Restraint System
(SRSCM)
The ignition key ON powers up the SRSCM, charges up
the reserve power, performs a diagnostic routine, and
turns ON the SRI for a bulb check. If a fault is
present, the SRI lamp illuminates. The SRSCM
continuously performs diagnostics on input sensors
and deployment devices. A serial communication line
is used to facilitate diagnosis with the Hi-Scan Pro.
The SRSCM uses input from FIS, SISs and internal
sensors to determine if deployment is necessary.
When deployment is needed, additional input sensors
are used, such as seat belt buckle switches, seat track
position sensor, and occupant classification system for
the SRSCM to determine which airbags and
pretensioners should deploy. The driver and
passenger airbags are dual squib and can fire 3
different intensities of low, medium and high.
