Santa Fe L4-2.4L (2001)
Impact Sensor: Description and Operation
SATELLITE SENSOR
The firing system for the side airbag consists of a SRSCM installed in the middle of the vehicle and two satellites - one on the left-hand side and one on
the right. Only the SRSCM is capable of releasing the airbags or the seat-belt pretensioners systems in the vehicle. In the dialog between the SRSCM and
the satellite, it is the SRSCM which makes the release decision.
The satellites act as intelligent acceleration sensors, and as such back up the central airbag controller. Both the satellites continuously report the current
system status on the left and right-hand sides of the vehicle to the SRSCM.
The test results are reported to the SRSCM by means of periodic status signals.
NOTE: When the ignition is ON, never cause a sudden shock around the installation area of the satellite sensor with a hammer, etc. Otherwise it could
cause the airbag system to unexpectedly deploy during servicing.
