Hi Folks,

I have recently been getting a Traction Failure message on the message centre. It comes with the ignition on even before starting the car.

I did do some searches and noticed about low volts could cause this so I've changed the battery to an Alphline 1000cca as recommended here but still the fault comes.

I have attached the nanocom but cant see any faults registered on ABS / motronic of Gearbox systems.

Anyone got a good place to start looking?

Thanks

OK a bit more info....I connected the nanocom and went for a drive. The aim was to monitor the wheel sensors to make sure they were all recording about the same. Trouble is as soon as I start to move nanocom displays "unable to perform function" and once its done this I can no longer establish communications with the ABS ECU until I turn the car off / on.

Does this sound like a potential ABS ECU issue?

Thanks again.

What voltage do you have at the battery with the engine running?

A trifle higher than normal but OK. ABS ECU's do fail.

Thanks. The fault seems to have stopped now! I'll see if it returns before replacing the ECU. The later ones are a bit pricey!

Well the fault hasn't returned so the battery replacement must have sorted it. Cheers guys.
