Sonata GL V6-2.5L (1999)
Impact Sensor: Description and Operation
The release system for the side airbag consists of a SRE-HMC installed in the middle of the vehicle and two satellites - one on the left-hand side and one
on the right. Only the SRE-HMC is capable of releasing the airbags or the seat-belt pretensioners systems in the vehicle. In the dialog between the
SRE-HMC and the satellite, it is the SRE-HMC which takes the release decision. The SRE-HMC is supported in connection with the side airbag function
by the two satellites, which 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 SRE-HMC.
It monitors the acceleration sensor continuously. The test results are reported to the SRE-HMC by means of periodic status signals.
