Rear door control module, purpose - GF72.29-P-4102-03I

Purpose 

The rear door control modules sense the window positions in the rear doors and transfer the information to the passenger compartment bus (CAN-B).

The automatic AC push-button control module reads in the signals for the rear door window positions via the CAN B bus to achieve better control when the windows are open.

When the convenience locking  feature is activated by pressing the recirculated air button ( ) or the activated charcoal filter button ( ) for ≥ 1.5 s a signal is sent via the CAN B bus to the rear door control modules, whereby the window positions are stored and all open windows are closed with the automatic one-touch up feature.

When the button is pressed again for ≥ 1.5 s the windows move back to the previously stored position.
