850 ABS ECU

[ChrisnChris]

Hi, my ABS has a fault, can anyone help.
The ABS warning light remains "on"
This doesn't happen all the time. It can go for weeks without any problem & then it happens, usually on start up although I think it has happened a couple of times whilst driving.
Has anyone used any ECU refurb services?....Oh & where is the ABS ECU

This is a very common problem, and if you're handy with a soldering iron you can attempt a repair yourself.

I did attempt this myself with limited success, but the problems came back after a while.

There is someone on ebay who advertises this service. I've never used him, but I'm tempted to as he has reasonably good feedback (the price seems to have dropped recently too).

Sometimes faulty ignition switches bring on the abs light.

if the switch sticks the indicators wont work also.
