|B153B GMC code description

The full open switch is part of the gear motor assembly and will close and become active when the liftgate reaches the full open position. The full open switch signal circuit is supplied battery voltage through a resistor and monitored within the Liftgate Control Module (LGM). The Liftgate Control Module provides a low reference circuit and when the switch contacts close, the signal circuit goes low and the LGM determines the switch to be active.
