Foreword [SAS Control Module (Two-Step Deployment Control System - Us/CANADA Spec.)]: Outline

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.
