Sunroof: Overview Mercury Mariner II

Principles of Operation

Roof Opening Panel - Actuating the roof opening panel switch in the forward or rearward direction supplies a ground signal to the roof opening panel module. The roof opening panel module then supplies power and ground to the roof opening panel motor. The vent and soft stop functions are controlled by the roof opening panel module and an internal roof opening panel position switch within the roof opening panel motor. These positions are obtained when an internal motor cam opens the roof opening panel position switch that removes ground to the roof opening panel module.

Normal Operation

When the roof opening panel glass is completely closed, it is flush with the roof panel and correctly sealed.

This pinpoint test is intended to diagnose the following

1. Roof opening panel glass adjustment

The roof opening panel module receives voltage on circuit CBP47 (GN/BU) when the ignition switch is in the ACC or ON position. The roof opening panel module is grounded through circuit GD182 (BK/GY). When the roof opening panel switch is pressed, circuit (BK) and circuit (WH) are connected for open/tilt down or circuit (BK) and circuit (VT) are connected for close/tilt up. The roof opening panel module controls the roof opening panel motor by directing power and ground on circuit (OG) and circuit (RD) to the motor.
