Seat Occupant Sensor: Description and Operation
Description
In order to make normal activation of airbag system, SRSCM detects DTC(s) for the Passenger side Body Detection System. If the seat is occupied, Body sensor detects how measuring electrostatic capacity and send signal to SRSCM via CAN.
SRSCM recognizes the signal as 2(two) different classifications; that is, class #1 (Empty or child seat), class #2 (Small, Large).
With these signal, ACU determines whether it needs to deploy PAB(Passenger Airbag) or not.
NOTE:
If you strike or spin the SRSCM with the IG "ON", the seat-belt pretensioner, curtain-airbag or side-airbag could be deployed. Handle it with care.
