hi ken
the intergral abs[servo assist]  system do tend to give that fault code.it could be a pressure switch that is faulty most of the time the dealers will tell you to replace the pump, how ever if you want to try repair it yourself there is a step by step instruction [if i can call it that] in the previous discussions on this forum

OK thank you for your reply on this. I will look into what you said as no way will it be going to the dealers as they charge more than an arm and a leg here. Again many thanks. Ken.
