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