ABS LIGHT VOLVO 850

My ABS WARNING LIGHT HAS BEEN COMING ON INTERMITTENTLY FOR A WHILE NOW AND A SLIGHT MOVEMENT OF THE IGNITION KEY PUTS IT OUT.WHEN IT IS SHOWING ALL LIGHTS SIDE/INDICATORS BECOME INOPERATIVE.I TOOK IT ON A GRAVEL ROAD THIS MORNING AND THE ABS IS PHYSICALLY WORKING WHEN LIGHT IS OFF BUT NOT WHEN LIGHT IS ON.I DID THE DIAGNOSTIC TESTING AS PER HAYNES MANUAL AND IT SHOWED 1 1 1 NO FAULT. ANY CLUES/ADVICE WOULD BE WELCOME. CHEERS CHARLIE

The ignition switch fails and keeps these circuits unenergized. Try moving the key the smallest amount.

Or just replace it.
