Could the valves in the pump be seized?

Any ideas?

The electronic ABS control unit including wheel sensors can be assumed being in order as you don't get any fault indication when turning on ignition and when driving.
You can do further tests by running ABS pump and operate each of the 4 valves. All you need is a cheap K-line multiplexer suitable for VAG-Com and DDT2000 software. I believe there are further details on how to set it up somewhere on this forum. You can then do diagnostics on most Renaults not requiring CAN for running diagnostics. This 10 pounds diagnostics system works fine on my 2002 Kangoo Trekka.
