Details of the b2948 OBD Code
Code B2948 relates to a fault in the immobilizer system of the vehicle.
OBD code B2948 means Mirror Switch Invalid Data Received.
This code is triggered by the Body Control Module (BCM) when it detects an issue with the mirror switch data it is receiving.
The mirror switch is part of the vehicle’s interior controls and is responsible for adjusting the mirrors.
When the BCM receives invalid data from the mirror switch, it sets code B2948 to indicate a problem with this component or its associated wiring.
Mechanic’s Tech Notes
