Code B1B96 Description

The diagnostic trouble code B1B96 indicates that the seat slide forward switch signal has been detected as stuck high. This means that the Driver Front Seat Module (DSM) is receiving a continuous signal from the seat control switch indicating that the seat should be moving forward, even when it is not being actively engaged by the driver. The DSM is responsible for controlling various functions of the driver’s seat, including its position, adjustments, and memory settings. When the switch is active for more than two minutes or is engaged during the self-test, the DSM triggers this code to alert the technician of a potential malfunction.
