Mazda 2: Air Bag System Wiring Diagram

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.

    PID/data monitor function: Reads out specific input/output signals and the system status.

  • Diagnostic 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.

FLOWCHART

• Use the following flowchart to verify the cause of the trouble.

NOTE:

• When inspecting past malfunction codes, inspect only the DTCs that were indicated before beginning the inspection. A mis-diagnosis could occur as a result of new DTCs being added while performing an inspection by disconnecting related parts or connectors.
• When DTCs of the present malfunction are no longer output after present or past malfunctions or both have been repaired, be sure to clear the past malfunction from memory to prevent repair of malfunctions that have already been repaired.
