Circuit/System Description

WARNING: This page is about a different car, the 2019 Buick Cascada, 2018 Buick Cascada, and 2017 Buick Cascada. However, it is still accessible from the selected car via links, so may be relevant.

The folding top control module checks the integrity of the signal circuits from the folding top/global window switch once every 50 ms. The folding top/global window switch is supplied with a reference voltage from the folding top control module via the folding top/global window switch open and close signal circuits. Activating the folding top/global window switch to the open or close position will pull the positive voltage to ground through a resistor. The folding top control module monitors these signal circuits to control the direction of the folding top.
