i have a fiat 500 1.2 sport and i have an ABS failure appear on the dash, when connected to a computer it comes up with Solenoid Valve Power Supply. This appeared after the RAC looked at the fuse box due to a bad rain spell, cleaned some fuses and the light appeared, took it to an auto electrician who cleaned all the fuses but light is still on....any ideas on what the issue could be?
