• The OBD (on-board diagnostic) system has the following functions:

? Malfunction detection function: Detects malfunctions in the air bag system and outputs DTCs (Diagnostic Trouble Codes).

? PID/data monitor function: Reads out specific input/output signals and the system status.

• DTCs can be read/cleared using the M-MDS.
