I need a little help with diagnosing an ABS problem. At idle the light isn't on, as soon as you move off you hear the click as the sensors detect rotation, and not sure if this puts the light on, but it quickly illuminates.

I have an OPCOM, no DTCs are present, can I determine if a particular sensor has a problem? If not, is it likely to be a sensor? I have read water ingress is common. If the ABS module had an issue, I assume i'd have more reported errors on the OPCOM?

Hope this makes sense, any assistance gratefully received

Plug Opcom in and record some live data. While on a good long run then someone will be able to tell you what's happening with the and system. If no fault codes are stored this is the best way to check
