•
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-
diagnostic function, which indicates system malfunctions using DTCs; a PID/data monitoring function, which
reads out specific input/output signals.
•
Using the WDS or equivalent, DTCs can be read out and deleted, and the PID/data monitoring function can be
activated.

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