Code B2355 2015 GMC Sierra Description

The Seat Memory Control Module monitors the position of the seat motors by using hall effect position sensors which are an internal part of each motor. The module supplies each sensor with a 12 V reference circuit only when any seat motor is active, and a low side signal circuit. During seat motor operation, the hall effect position sensor provides a determined number of pulse signals for every revolution of the motor shaft. The scan tool displays these pulse signals as counts that range from 0–65,535. The module counts the feedback pulses from each sensor to determine seat position and end-of-travel limits for each of the seat motors. High scan tool count values indicate forward or upward seat positions while low count values indicate rearward or downward seat positions. The Diagnostic Trouble Code (DTC) will be set when there is a fault in the Driver Seat Front Vertical Position Sensor Circuit.
