Code B00CA Description

The B00CA diagnostic trouble code (DTC) specifically refers to a fault detected in the Passenger Seat Occupant Position Sensor 'D'. This sensor is responsible for detecting the presence and position of a passenger in the front passenger seat. The sensor plays a crucial role in the proper deployment of the airbag system in the event of a collision. When the sensor detects a passenger in the seat, it communicates this information to the airbag control module, which then determines the appropriate deployment strategy for the airbag.

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.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
