Started getting these ABS/ESP/ASR/HH errors lately. It's happening more and more often. Happens only when I press the brake pedal. Sometimes it triggers even when the car's not moving.

Any ideas, what to check, before I start giving € to my Fiat dealer? I remember that Stilos had a similar problem, which was connected to a faulty brake light switch. Could it be the same with our GP's?

you need a diagnostics test, or you could just keep guessing and throw money down the drain. fiatecuscan will tell you what part is faulty and causing the dash lights.

mines been doing it lately and its the wiring to abs sensor

Borrowed scanning tools from a friend and got this: P0504 - Brake Switch (intermittent).

The switch is cheap, I'll go get it tommorow. But how do I access it and replace it? Any ideas?

get on ya knees and look behind brake pedal id assumes its clipped in a screwed

Got the same problem and error message reported in AlfaOBD. However, there is a front and rear ABS sensor. How do I know which one I need to replace?

My car does this but only when on a slight slope. If I move the car onto the flat and turn the engine off and back on, it goes. I don't know what to do about it. I have read it could be something to do with the tracking which I haven't had done since buying the car nearly a month and a half ago.

Eh? The error code relates to the brake pedal switch and not an abs sensor (aka wheel speed sensor, of which there are 4).

I might have this completely wrong then. The error message reported in AlfaOBD is "B1010 - Brake switch (Error intermittent)"; which replacement part do I need then (OEM code maybe)?

So to get this right, is the aforementioned error actually related to this part:

(By the way how does the brake light switch actually affect the entire system so that the ABS/ESP/ASP and hill holder are disabled?!)

Because the esp system needs to know whether you are braking or not, it gets that info from the pedal switch.
