FOREWORD
OUTLINE
The OBD (on-board diagnostic) system has the following functions:
Malfunction detection function: Detects malfunctions in the air bag system and outputs DTCs.
Data monitor function: Reads out specific input/output signals and the system status.
Diagnostic DTCs can be read/cleared using the M-MDS.
FLOWCHART
Use the following flowchart to verify the cause of the trouble.
NOTE:
While performing the inspection of the past malfunction code, the
applicable DTCs may be added to memory by removing or disconnecting
the related parts. Inspect only the DTCs that were indicated before
inspecting.
When DTCs of the present malfunction are no longer output after present
or past malfunctions or both have been repaired, be sure to perform past
malfunction display cancellation to prevent repair of malfunctions that
have already been repaired.
