PINPOINT TEST 6: THE EXPRESS OPEN/CLOSE IS INOPERATIVE

Normal Operation

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 (Y/O) and (W/L) 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 (V/BR) and (W/L) 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).

Possible Causes
- Roof opening panel motor initialization
- Wiring, terminals or connectors
