Code B2755 2014 GMC Sierra Description

Low reference is supplied to the driver Seat Memory Switch from the Seat Memory Control Module. When a memory switch is pressed, the signal circuit from the Seat Memory Control Module is pulled low through the switch contacts and a series of resistors indicating the memory recall request. In response to this signal, the Seat Memory Control Module commands the appropriate seat motors to move to the pre-recorded seat positions stored in memory. If the Seat Memory Control Module detects a short to ground on the memory seat switch signal circuit this Diagnostic Trouble Code (DTC) will be set.
