Details of the b2a05 OBD Code
Fault code B2A05 relates to a potential issue with the occupant classification system in the vehicle.
OBD code B2A05 means Left Rear Side Object Detection Sensor 1 Circuit Low.
This code is triggered by the Body Control Module (BCM) when it detects a low voltage signal from the left rear side object detection sensor 1. This sensor is part of the vehicle’s parking assist system and is responsible for detecting obstacles on the left rear side of the vehicle.
When the voltage signal from this sensor falls below a specified threshold, the BCM sets code B2A05 to indicate a circuit low condition.
Mechanic’s Tech Notes
