ABS light (intermittent)

Recommended Posts

Hello everyone. Im sure this is a common fault and im not asking how to fix it, I just want some advice on how to diagnose it. 

I have used the car's own self diagnostic system and found that there are no DTC codes stored. I would like to know which of the four wheels has the fault so I can direct my attention in the correct place and save myself a lot of time and effort.

 I dont have the kind of money to start buying Delphi diagnostic equipment and I dont want to waste money on something that returns the same result as the self diagnostic system i.e. "DTC none". Does anyone know of anything on the market that will pin point where my ABS fault lies via the diagnostic port? My vehicle is a Ford Focus 1.6 2002.

Many thanks.

The so called ‘self test’ is a complete waste of time.

you'd probably be best to look at getting a lead from eBay and downloading Forscan, so this setup will cost you say, £20.

Then you can atleast see what is coming up and start to diagnose from that information.

Being the owner of obd code reader from tunnelrat electronics (their advertised price includes uk postage) and free forscan software on windows laptop. And paid for forscan for iPhone about 7 quid I think, I would expect it to show you some fault codes. Get the modified code reader with the extra switch

Ive just googled this. Do you have the ELM327? It looks like there is a USB version and a wifi version. Is it the USB version you recommend? It has a "HS-MS CAN Switch" whatever that is 🤔

Yes, you want the ELM327 with the HS-MS Can switch. The switch allows you to change between the two Can networks that Ford use. Some modules in the car are on the HS CAN and others are on the MS-CAN. The Tunnelrat version is highly recommended, it's not worth trying to save a few quid on a cheap version that might not work. Get the USB version if running Forscan on a Windows laptop or the WiFi version if running Forscan on an iPhone. The windows version of Forscan has more features than the iPhone version.
