Assuming problem is with the ECU (under front seat) have you tried drying it out. It is fairly easy to remove plastic cover to get access to circuit board inside the ECU to dry it out thoroughly. If one of the components on the board is damaged/shorting the above probably won't help much (unless you have the electronic skills to repair the faulty component or disconnect the wire from /to the faulty item in the ECU). If all else fails suggest you can disconnect the plugs from the ECU until you get a new unit. The ECU controls other functions such as curtesy light and alarm so you will lose them when you disconnect the plugs. At least it should stop the doors unlocking.

Thanks for all the suggestions. I will try looking at the wheel sensors when the weather gets a bit warmer. Failing that I will have to find someone to sort it out for me. Oh..... its just passed the MOT!

I thought something like that may be happening. I have tried driving for 2 or 3 minutes at 10 mph - no abs light. As soon as speedo shows 15mph the light comes on. Braking and time taken to reach 15mph seems to make no difference. It all makes me wonder what the significance of 15mph is. Maybe it is just a fault on my car and the abs is not activating until 15mph instead of 3mph??? If its the abs unit its very expensive and probably means taking it to Ford - I don't trust any of them!

The Haynes manual says the ABS functions at speeds over 3 mph. This would suggest that it is working between 3 and 15 mph as the light stays out until 15 mph. Does anyone know whether 15 mph is significant or is it just peculiar to my car?

Does anyone have any suggestions on the following: ABS warning light goes out after starting engine - after about 3 seconds. Warning light comes on again when travelling at about 15 mph and stays on. Brakes appear to be working normally, except no ABS.

<_< Does anyone know whether there is a non-Ford option for replacing central locking/alarm module. Presumably Cobra, Toad etc. etc. supply modules that do the same thing????
