Fuel Pump Driver Control Module

WARNING: This page is about a different variant/trim than selected.

The fuel pump driver control module is a serviceable GMLAN module. The fuel pump driver control module receives the desired fuel pressure message from the engine control module (ECM) and controls the fuel pump located within the fuel tank to achieve the desired fuel pressure. The fuel pump driver control module sends a PWM signal to the fuel pump, and pump speed is changed by varying the duty cycle of this signal.
