ON-BOARD DIAGNOSTIC [AIR BAG SYSTEM]
FOREWORD
Outline
• 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.
• 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
— Active command mode
• Diagnostic DTC can be read/cleared, using the SST (WDS or equivalent).
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 (WDS or equivalent).
