Air Bag Control Module: Description and Operation
The SRS airbag system has sophisticate electrical and electronic components, therefore the airbag operating components should be handled very
carefully.
SRSCM (Supplemental Restraint System Control Module)
SRSCM determines to deploy the airbag module by sensing the frontal and side impact sensed by the sensor built in SRSCM.
Back-Up Power
The SRSCM reserves the energy supply to provide deployment energy for a short second when the vehicle voltage is low or if lost in a vehicle frontal
crash.
Malfunction Detection
The SRSCM continuously monitors the current SRS operation status while the ignition key is turned on and detects the malfunction of the system. The
malfunction can be displayed in the form of diagnostic trouble code using Scan tool.
Malfunction Recording
Once a fault occurred in the system SRSCM records the fault in the memory in the form of DTC and the DTC is erased only by Scan tool.
After firing the airbags once, the SRSCM cannot be used again and must be replaced.
