What is B0955?
The diagnostic trouble code (DTC) B0955 indicates a problem with the seat position sensor circuit, which can affect the functionality of the power seat in your vehicle. Essentially, this code means that the seat position sensor is either providing incorrect readings or is failing to communicate properly with the vehicle's onboard diagnostic system. This can lead to issues such as the seat not adjusting correctly, or it may even affect the deployment of the airbags in certain circumstances, as the vehicle may not be able to determine the driver's position correctly. If you see this code, it’s crucial to address it promptly, as ignoring it could lead to further complications. Commonly seen in 2016-2020 Ford F-150 models, as well as other Ford vehicles, this code can stem from faulty wiring, a defective seat position sensor, or issues within the body control module (BCM). Drivers may notice that the seat doesn’t move as expected or that the seat settings are lost after turning off the engine. Since this code relates to safety and comfort, understanding its implications and addressing it swiftly is essential for maintaining vehicle integrity.
