Description And Operation: Operation

The Body Control Module (BCM) supplies the controls on the driver's door and passenger side in accordance with the "comfort enable" logic This power supply also lights up the LEDs and supplies the controls.

The motors receive power supply from the BCM, via the line protected by fuses.

The BCM receives a direct power supply from the battery through the line protected by a fuse located in the engine compartment junction unit.

The BCM receives an ignition-operated power supply (INT). This this signal is used, amongst other things, to "wake up the network".

The signal that controls the automatic operation is sent via the LIN to the internal electronic circuit of motors.

Passenger side window controls, built into the unit are re-sent to control through the BCM and the above mentioned LIN line.
