Code B1B97 Lincoln Description

The diagnostic trouble code (DTC) B1B97 indicates that the seat slide backward switch signal is stuck high, meaning that the signal indicating the seat is moving backward is continuously active. This situation can occur if the seat control switch is engaged for more than two minutes or if it remains active during the vehicle's self-test phase. The Driver Front Seat Module (DSM) monitors the position and function of the seat adjustments, including the slide mechanism. When the switch signal is stuck high, it can lead to unintended seat movement, which may compromise driver comfort and safety. If ignored, this issue can result in increased wear on the seat adjustment components and may lead to further electrical problems in the seat control system. Over time, continued operation with this DTC may also affect the functionality of other systems that rely on the DSM, such as airbag deployment, as the seat position is critical for proper airbag operation. Therefore, addressing this code promptly is essential to ensure the vehicle's safety features remain operational and to prevent more extensive repairs down the line.
