On-Board Diagnostic (Restraints): Foreword: Outline: Notes

The OBD (on-board diagnostic) test inspects the integrity and function of the air bag system and outputs the results when requested by the specific tests.
The OBD test also:
- Provides a quick inspection of the air bag system.
- Is usually performed at the start of each diagnostic procedure.
- Provides verification after repairs to ensure that no other faults occurred during service.
The OBD test is divided into three tests:
- Read/clear diagnostic results
- PID/data monitor and record
The diagnostic DTC can be read/cleared, using the SST (M-MDS).
NOTE:
- When the air bag system is malfunctioning, turn the ignition switch to the ON position to display the current DTC, using the air bag system warning light on the instrument cluster. However this light is strictly for reference. Make sure to inspect the system, using the SST (M-MDS).
