id080200100100

• The on-board diagnostic function consists of the following functions: a failure detection function, which detects malfunctions in the air bag system-related parts; a memory function, which stores detected DTCs; a self-malfunction diagnostic function, which indicates system malfunctions using DTCs; a PID/data monitoring function, which reads out specific input/output signals.

• Using a WDS or equivalent, DTCs can be read out and deleted, and the PID/data monitoring function and active command mode function can be activated.

• A fail-safe function, which prevents the abrupt activation of the air bag module and the pre-tensioner seat belt in case of an air bag system malfunction, is included.
