Frequently Asked Questions

Can I still drive with this code?

Yes, this code only affects the seat memory and auto-positioning features. The seat can still be adjusted manually using the power seat controls.

What does the seat track position sensor do?

It monitors the fore-aft position of the driver seat so the memory system can recall and restore saved seating positions when the driver enters the vehicle.

Is this a common issue on luxury cars?

Yes, vehicles with memory seat systems are more prone to this code because they rely on multiple position sensors along the seat tracks that can wear over time.
