B0001 Mazda Meaning
The Driver Air Bag Module is dual stage and is wired to the Air Bag Diagnosis Sensor unit through the Clock Spring. The Air Bag Diagnosis Sensor unit will monitor for opens and shorts in detected lines to the Driver Air Bag Module including the Clock Spring. The Air Bag Sensor Unit (Air Bag Control Module) monitors the Driver Air Bag Module. The Air Bag Sensor Unit sets the OBDII code when the Driver Air Bag Module is not to factory specifications.
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
