Code B2117 GMC Description

The Power Seat Position Sensor that sets this Diagnostic Trouble Code (DTC) is either attached to the seat directional motor drive cable or directly to the motor it monitors. It receives a 5 V reference and ground from the Memory Seat Module (MSM). The sensor sends a voltage signal that varies with the movement of the seat through the signal circuit to the MSM. Then based on this voltage signal, the MSM determines the position of the seat. If the MSM sees the analog input from this sensor as either lower than 0.25 V or higher than 4.75 V, the sensor will be considered out of range and the MSM will set this DTC.
