4) Internal monitoring

The air bag unit checks the status of the air bag system and monitors the system for internal errors. If
an error is detected by self diagnosis, this unit disables part of the air bag system functions and outputs
a diagnostic trouble code (DTC) and air bag warning lamp signal.
-

Watchdog

The micro controller is monitored periodically. And if a fault is found, micro controller is reset, inflator
ignition function is limited, and the air bag warning lamp comes on.
-

Internal acceleration sensor test

The air bag unit checks internal acceleration sensor when the ignition is turned on. The air bag unit
determines the deployment of the air bag for the collision signal input after the diagnosis.
-

Non-volatile memory (NVM) test

The air bag unit checks the values stored in the memory. If the values are not correct, the air bag unit
sets a diagnostic trouble code (DTC) and turns on the air bag warning lamp.
