Refer to Convertible Top for schematic and connector information.
Normal Operation and Fault Conditions
The convertible top switch is a 3-position rocker switch, the UP circuit is hardwired to the Moveable Roof Control Module A (MRCMA) / Convertible Top Motor 1 and the DOWN circuit is hardwired to the Moveable Roof Control Module B (MRCMB) / Convertible Top Motor 2. When the switch is pressed, the applicable module receives a ground signal and roof operation is initiated. The switch is designed so that both circuits (UP and DOWN) cannot be activated at the same time. The modules share the convertible top switch status on the MS-CAN. When the switch or one of the circuits is faulted, the convertible top does not operate. The convertible top switch is located in the overhead console and is serviced with the console assembly.
