Roof works but will not complete cycle

[Yrrag_lean]

Hi all first post, have read all relivant posts but can't find a solution. 206 cc 1.6 2001 manual, roof works great but don't give dong to say it's finished the cycle, connected pp2000 fault codes saying there is a short to positive, disconnected all the micro switches still says the same thing, checked visually the wiring all looks very good, could it be the roof ecu at fault, best regs gaz

same thing here but running switch state check with pp2000 shows that boot locked switch does not function.
i need to update my thread and get back to ianL maybe he has an idea.

If the only problem is the lack of dong, does it dong when you release the catches with the ignition on? If not, it may simply be a defective "donger".

Hi thanks for reply, tested the dong in pp2000 and works fine, disconnected all 11 micro switches and pp2000 is telling me open circuit or short to earth could it be faulty roof ecu, regs gaz.

I suppose if you are confident about the wiring, and the switches were disconnected, the Roof ECU is all that is left. Perhaps you can borrow one from someone nearby? If not, a scrapyard or EBay.

Yes will have to try another ecu, heated rear window not working also but I think the roof ecu has some control of this also the windows, many thanks for replys

If it is working OK except for the final bong, I would not worry about it. You may make things worse!
Ours doesn't always bong at the end of the cycle, but works perfectly without.

Its happened to me too a few times. You sit there like a lemon - waiting - waiting - wondering what you've done wrong. Will it ever work again? Dong or no dong, it always seems to work.

Ordered ecu from eBay will post results when changed,regards

Sorry for not replying sooner. Does this happen on every operation of the roof? I know that sometimes (normally on lowering but has happened on raising as well) I will not get the dong on completion. As I'm rather paranoid I normally raise and lower (or visa versa) again and it hasn't failed to give the confirmation sound the second time. May be worth a shot?

[IanL]

Maybe it refuses to dong if the operation was a bit slow. Try lubricating the hinges, etc and see if that makes a difference.

Hi all, roof works ok but when lowering roof the windows do not go down automaticley and no bong means they do not work and get constant beeping over 5kph when driving also rear heated window dont work not as I need it yet, waiting for second hand roof ecu to come. Windows work fine with roof up stripped all the boot and back seats out to check wiring all looks good regards gaz

Did you check the wiring under the boot lid lining? There is a joint which came loose on our once .. and it bleeped over 5!

[Yrrag_lean]

Yes stripped plastic trunking off all of it no breaks and if u put a volt meter on the boot switch I am getting a osilating current which comes from the roof ecu with ignition on

[Yrrag_lean]

Not the ecu changed it and just the same,then decided it must be wiring, hey Preston two broken wires from rear boot lid harness where it bends, works perfect now and got a spare roof ecu if any one wants it, many thanks for all suggestions best regs gaz
