The above message appears on my 2002 115psi Ghia, sometimes as soon as I turn igniiton on; alternatively when I start engine. The brakes work fine. When I consult the handbook & FSE disc no detail is given. All pads & discs are in good condition, being changed earlier this year. Fluid level is okay. I have had wheels off and visually checked all brake components. Nothing is obviously wrong. (I re-bled front brakes just to be doubly sure, but there was no air. When I changed pads 3 months & 2,000 miles ago, I clamped hose and released bleed nipples). Any suggestions as to what is giving rise to warning?!
