B3682



DTC B3682

CIRCUIT DESCRIPTION
The roof door module (RDM) monitors the folding top motor relay control output circuits from RDM at least once every 2 milliseconds. The folding top motor control relays have ignition 0 voltage supplied. As the folding top control switch is applied to either the open or close position, the RDM will apply the appropriate relay output control that will control the folding top pump motor direction for the hydraulic pump to move the roof system to the desired direction.
