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 monitors two hall-effect switches for the folding top header latches: The left and right folding top header latched position sensors. The switches monitor the status of the folding top header latches.
The sensors are two-wire hall effect sensors providing an input to the folding top control module. One circuit is low reference and the other is a signal circuit.
