Code B1750 2014 GMC Sierra Description

The Seat Memory Control Module supplies a reference voltage to each signal circuit of the Driver Seat Adjuster Switch. When the power seat or lumbar switches are pressed, the appropriate signal circuit from the Seat Memory Control Module is pulled low through the switch contacts indicating the power seat command. The Seat Memory Control Module then commands the driver seat or lumbar to move in response to the switch signals. The Diagnostic Trouble Code (DTC) will be set when there is a short to ground on a switch signal circuit.
