    1991 Mondial T ABS light flashes 3 times-3 times stays on 4th flash, I think that it is the code for right rear wheel, checked sensor and continuity to controller on both left and right, all is good, this came up after doing an engine out service, anyone have an idea what it is

    The Teves ABS Mk II manual indicates code 3.3 is the right rear sensor. Lack of signal due to short circuit or breakage (or internal control unit failure). Check sensor resistance and continuity. Resistance should be 800 to 1,400 KOhm. Not sure what else to check, other than clearing the codes in the check system and seeing if they reappear after driving a bit more.

    1) you don't clear the code. It clears itself when the problem goes away and you have driven the car over 30 mph.

    2) did you plug the ABS sensor connector back after the engine out? If yes, then did you mess up the connector when you played with it? Use compressed air to clean out the hole where the sensor goes into the wheel hub. Sometimes that helps.

    Here are the Ferrari ABS manual extracts relating to code reading, clearing, etc. A bit blurred in spots, let me know if you need anything clarified.
