B1962 – OBD-II DTC

OBD-II DTC B1962 – Seat Horizontal Forward/Rearward Potentiometer Feedback Circuit Failure

DTC B1962 meaning

DTC B1962 refers to a fault in the seat horizontal forward/rearward potentiometer feedback circuit. This circuit is responsible for monitoring the position of the seat adjustment mechanism, allowing the vehicle’s control module to determine if the seat is moving correctly in response to user inputs. When this code is triggered, it indicates that the feedback from the potentiometer is not within the expected range, suggesting a malfunction in the circuit or the potentiometer itself.
