Smart roadster ABS problem

[bunduc.alexandru23]

I don.t know what size they are i will check tomorrow...what do you mean with a clean reconnection?

.........what do you mean with a clean reconnection?

Put the connector on as quick & as positively as you can ie avoid it sparking and arcing as you put it on the battery post. I don't think it'll help you though

[bunduc.alexandru23]

at least i try something...

[bunduc.alexandru23]

after this reset i will turn the computer or that ecu to factory base? because i have remapped the system and is a verry good one...it gives me more preassure in the turbo and i don.t want to lose it

I've never heard of a remap being lost due to battery disconnection (when remaps are lost it is usually after a dealer reflash) but I can't say for sure. Someone here should know though.
Meantimes, until confirmed (one way or the other) leave out disconnect for now and come back with tyre sizes. It should be obvious from them if they are the cause of the problem.

Your remap is perfectly safe.

It's like asking will I still have windows 7 when I fully reset your PC, you might have to reset the time, but you'll still have windows 7

That thing that you said it will read the tyre size by it.s own?

The computer is only looking for variations (of rpm) between wheels , it doesn't really need to know the tyre size ,just any variations between each corner.
If you have three normal tyres and one (or even 2) oversize one(s) it would complain.
Slight variations between front and rear are catered for though.

Bigger diameter=lower rpm in comparison to a smaller diameter.

Cheers TAIM - computers aren't my strong point!

[bunduc.alexandru23]

So now i.m at the car i just disconnected the battery and i.m waiting 30 min. The tyre size is 205/45ZR16

[bunduc.alexandru23]

And i hope at least the tyre size i know how to read

[bunduc.alexandru23]

What can i tell you more i have 3 tyres the same and one different on the front left they are all the same size and all new with the same amount of thread left i checked with an coin)

[Thrumbleux]

OK, all 4 tyres are 205/45. 16. Are they all at the correct pressure?

[bunduc.alexandru23]

Yes i just did it yesterday

[bunduc.alexandru23]

I will put the battery now back...i hope i don.t need to sincronize the keys after...

[bunduc.alexandru23]

Something else special to do before or after i reconnect the battery?

[bunduc.alexandru23]

Pressure is 2.2

[Thrumbleux]

Hook up the battery and go drive - with your fingers crossed.

[bunduc.alexandru23]

Nothing...it.s the same...+ it shows me the petrol thank it.s empty 0...
