Foreword [Standard Deployment Control System]: Outline

WARNING: This page is about a different car, the 2016 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.

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.

NOTE:

Use the M-MDS to verify DTCs because the DTCs displayed by the air bag system warning light are reference information only.
