Normal Operation and Fault Conditions
The convertible top latch switch is hardwired to the Moveable Roof Control Module A (MRCMA). The Moveable Roof Control Module A (MRCMA) sends out a 5 volt reference signal to the Hall-effect switch and receives a voltage signal input back from the switch when the latch is open. When the latch switch or circuit is faulted, the convertible top may close, but does not open. Also, depending on the nature of the fault, the message center may display the TOP NOT SECURE. The convertible top latch switch is part of the convertible roof latch and striker assembly.
