ABS and traction control problem

#1
hi there

ive got a strange issue with my traction control and abs system.

on first start the yellow light for both systems is on, but if you turn the car if and back on, the lights disappear and the systems work perfect.

when I took the car for diagnostics they said that the fault reads that the Abs computer needs replacing. that's it!

has anyone seen or better still found a fix for this, and what are the root causes?

hi there,

I got an opcom and diagnosed the fault as c0550 image attached.

what the hell is this!? it doesn't come on very often so it took me a while to catch. can someone offer some guidance as to what to do next, as in is it just the electrical part needs replacing, as I've never seen this before.

thank you
