Code B1826 GMC Description

The sensor that sets this Diagnostic Trouble Code (DTC) is attached to the seat directional motor it monitors. It receives a 5-volt reference and low reference from the Memory Seat Module (MSM)/Driver Position Module (DPM). The sensor sends a voltage signal that varies with the movement of the seat through the sensor signal circuit to the MSM/DPM. Then based on this voltage signal, the MSM/DPM determines the position of the seat.
