F430f1 Spider Roof dead as a dornail

My Autel A200 shows the switch status and its pretty cheap.

Make sure your engine lid is closed (check dash for no lid warning light).

Here is the full logic for pump operation (roof opening):

Step 1: Vehicle speed <5kph, battery power ok, engine lid closed, pump temperature <95C
Step 2: Push roof down button. This will send a signal to the Window ECU to lower the windows. When the windows are completely lowered, step 3 begins. Window position switches must be functioning and the Window ECU must be powered (fuses PSF3 & PSF7).
Step 3: The small flaps (near the roll bars) are momentarily powered to ensure they are the down position.

Before you order a scanner, maybe you could check the roof switch on the console with an ohmmeter. If the switch is getting power, the roof switch should be illuminated.

 

Hope they were quality fuses. The boxes of hundreds of fuses you see on eBay/Amazon are not good quality and have unreliable melting points.... so I've been told (by YouTubers).

 

I have the same exact issue with my 2007 430 and tried these same fixes.Hard to explain but the problem is disguised by the strange effects of stopping the switch in the middle of opening. This makes it have odd issues that made the problem hard to understand. It was the pin that guides last hatch from closing. They are thick about 3 ins (10 CM) long on each side near the outside. It was bent a bit in the past so I bent it inwards and issue stopped. A new pin is about $120 but the problem seemed solved by bending it inward. Why it makes the lid stop halfway isnt clear. I can post a pic if you like. I plan to sell the car for $105K so I have a lot of pics. It is a CPO.

Can you manually lower the windows and then operate the roof?

 

As I said in post #2, the Window ECU is the brains of the window/door system and communicates with the Alarm ECU. I would at least try resetting the plugs on the Window ECU. If the Window ECU is not getting the right signals from the window position microswitches in the doors, perhaps it may also be stopping doorlocking and roof operation. Maybe ask other 430 owners if their doors lock with the windows down?

You can check the functioning of the window (down) position microswitches with wiring checks from the plugs on the Window ECU.

 

Hmmm.. .I'm not sure if you can access the Window ECU plugs without disassembling the dash...

Also, I don't know if the Window ECU is on the driver's side on a RHD car.

It may be best to wait for the scanner. That should tell you if the correct signals are coming from the Window ECU (to the Roof ECU).

If the plugs are easy to get to on the Window ECU, here are the pins to check...

Compare the left and right door signals with the windows up/down.

Plug C is the smaller plug of the lower two plugs.

 

Also the scanner will tell you of any errors that may point to an issue

 

Ian ( Qavion) is awesome - a great asset to this community when it comes to electrically wiring / circuits of our cars
To answer your question - no need to disconnect of course unless you are looking at certain voltages etc - something that the saver may throw off

 

Unfortunately, I sometimes focus on wiring too much for diagnosis purposes … and forget what these new fangled scanners can tell us.

 

It really doesn't make much of a difference but technically you should be using evo 8
