Normal Operation
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
When the rear portion of the roof opening panel switch is pressed to the second detent position, a ground signal is sent to the roof opening panel motor through circuit CPR40 (YE/OG) and CPR38 (WH/BU) which causes the roof opening panel to perform a one-touch open operation. When the front portion of the roof opening panel switch is pressed to the second detent position, a ground signal is sent to the roof opening panel motor through circuit CPR31 (VT/BN) and CPR38 (WH/BU) which causes the roof opening panel to perform a one-touch close operation (or tilt if roof opening panel glass is already in the fully CLOSED position).
This pinpoint test is intended to diagnose the following:
- Roof opening panel motor initialization
- Wiring, terminals or connectors
- Roof opening panel motor
- Roof opening panel module
