DESCRIPTION AND OPERATION
Front window motors
The front window motors are permanent magnet motors. There is a window motor in each front door. The front
window motors are controlled by the BCU.
The BCU provides both the voltage and the earth paths to the front window motors. The BCU reverses the direction
the window motor operates by switching the voltage and earth paths to the window motor. The BCU also monitors
stall current for the front window motors.
TestBook can operate the front window motors remotely.
