So is our next step, is to start replacing the microswitches?
EFA (5Q), flaps lowered, ,microswitch is working. The flaps aren't contacting it well probably due to the manual flap lowering for the manual top raising that was done. I was able to access the microswitch and get it to contact. Once I had contact, I tested the resistance and got high resistance for it. I cannot however get to the flaps up microswitch with the top currently up. OK BREAKING NEWS! With me manually holding the flaps open microswitch closed, activating the switch causes the motor to run. Should I try to lower the top?
Yay... some progress. I think that's why one of the Roof ECU's first steps is to drive the flap down momentarily (even though it should already be down). That doesn't explain why the other switch is showing closed (and the roof is still operating). The switches should be in opposite states. Image Unavailable, Please Login
That depends on whether you lose your already minimal access the flap microswitches. I guess you will have no chance with the flap up (?). Does the roof now drive in both directions without you constantly pushing on the switch? We also have to figure out if the flap motor is also running (to push on the flap open switch). The flap open switch may be faulty or the motor/motor drive system may be faulty. We also have to figure out why the flap up switch is showing closed (logic 1) By the way, what did you use to push on the flap open switch? Could you have achieved the same just by pushing on the flap?
No. I have to hold the switch to get it moving either direction. I haven't fully opened the top and allowed the capote flaps to close yet. I've driven it to about 3/4 open then back to full closed.
I'll have to do some reading. I don't know if the top closed signal is based on all the microswitches being in the right place or just one (say, the front hook microswitch/es)
Eureka! Well mostly eureka.... Ok so I can get the top to go down holding the flap open and of course releasing it to get the capotes to close. Secondly, I believe the elastics in my roof are worn, because the big bar that runs through the center of the roof was not pulling back, thus not allowing the roof to fold completely to fit in the bay.
The microswitch is definitely not aligned right that needs to be fixed and the elastics need to be replaced I'm guessing.
@DrivnXcitment @Qavion Excellent work! It proves one thing. Persistence pays off. I believe the indication on the dash is linked to the capote cover locking microswitch which is on top of the capote cover hinge, left side. If the rams aren't pushing the "kinematics" to the locked position, then that microswitch is still in the open condition. Typically, you'll hear a snap sound when the cover locks and the cycle completes. as for the elastics, I wrote a how-to on that one. https://www.ferrari360.org/2020/09/capote-elastic-bands-and-more.html It's about a four hour job, all standing up. Very little back pain involved.
No clues in the manuals (after a quick read). Capotes? Do you mean the flaps, the lid or something else?
Wouldn't the roof light be dependent on the final stage of closing? 9. The hooks are closed by activating the solenoid valve operating the hooks (MVVZ). The striker plate micro-switches ((EVVDL and EVVDR connected in series to each other ) and the cross member (EVVZ) indicate that the hooks have closed and that the front part of the soft top has locked onto the cross-member. The roof would be unsafe without confirmation from EVVZ.

Even with new elastics and flap fully down switch adjustment, we still have to figure out why the flap fully up switch isn't showing the opposite state to the flap fully down switch. Did you get the flaps to go fully up during the roof opening procedure? Did the flap motor operate? And did it stop running when the flaps were was fully up?
The flap down microswitch is good, the capote mechanism just is not making contact with it. I can't quite see where the capote hits the switch, I just access it through a VERY tiny hole in the frame where it mounts. NO definitely not pushing on the flap, those things are fragile and the mounting points are known to snap.
I will check and see. I haven't closed them completely yet. Baby steps HAHA The flap motor does operate and the flaps are moving up like they should. If the down microwitch shows high resistance (grounded) when I depress it manually, wouldn't that be the opposite state of the up capote flap microswitch with currently no resistance? I haven't pulled the connector from the ECU to check it with the top completely stowed yet. I guess that would be the next stop?? To see if the up flap microswitch was showing high resistance (ie engaged)
The WSM says the down switch should be logic 1. This term can be ambiguous. Looks like Ferrari took this to mean open circuit (high resistance to ground). On other cars or even on other Ferrari F430 systems, it may mean the opposite. I just assumed it meant a closed circuit (low resitance to ground). Normally, most vehicle microswitches are set up so that the circuit closes when you push on them (but not always). So, if the roof operates and you are getting opposite states on the up and down switches, all seems to be ok. The only time you will get the same signals on both flap microswitches will be when the flap is between fully up and fully down. Looking at the table for the entire roof sequence (up and down), I guess we have to assume that all the logic 1's are open circuit (high resistance) and all the logic 0's are closed circuit (low resistance). That's definitely something to be remembered for the future.
I can't thank you and John enough for walking with me through this journey!!! While I'm far from the end of it, I never could've made it this far without you two for sure!
One "smidgen" at a time Thanks, but we weren't always leading you in the right direction. At least we both learnt a lot though this process. I guess there is no way to easily access the mounting bolt/s for the microswitch, so this may still be an expensive process. Is there any way of removing some of the flap mounting bolts to get better access?
LOL... A forum search may have got us to the answer a lot quicker. I forgot about Tom's comments in this thread (despite the solution in that thread being a fuse). https://www.ferrarichat.com/forum/posts/149134420/
We shall see. I'm going to review the WSM for the top, there was something about the capote adjustments and the microswitches. I just have to find that page again. Been bouncing between my daughter, decorating for christmas, fixing the car, smoking a pork butt, and getting ready for a christmas party all at the same time. It's been quite the juggling act for sure. Hence my disjointed answers sometimes.
Tom response also mentions a way to access the switch. https://www.ferrarichat.com/forum/posts/149135136/
