Hello,
I have FIAT Marea ELX model 2001.
The car have 132000 km.
Last "Big" treatment was 10,000 km ago & included replacing breaks,
ABS magnets in the rear wheels, oil etc.
Even before the treatment and after it the break & ABS warning lights
don't turn off after engine start and sometimes after few seconds they turn on. In the garage they say it's probably a problem in the computer (a relay problem).
Can anyone help / give a tip before I have to spent a lot of money on a new computer ?:bang:

Hi Irad and welcome to our forum

There is very little that can be done on the ABS system without special equipment.

You can check that the sensors and toothed rotors are clean and that the gaps are:
Front 0.645mm to 1.305mm
Rear 0.06mm to 1.18mm.

Check the connectors as well.
