3 STOP CAR, STOPS SHORT ABOUT 3 INCHES FROM THE TOP FLOOR THEN FAULTS TO A 111 X 191. SAYS, NEVER SEEN SLOWDOW CHECK MAGS OR SENSEORS .CHANGE MOD A CEDES, AND CIOACD2Q WITH THE SAME ISSUE STILL. ANYONE SEEN THIS BEFORE .ONLY HAPPENS AT TOP FLOOR .
Is it a fairly new unit? The newer ones have 2 float switches in the tank. If there isn't enough oil when it gets to the top floor, the float switch trips and shuts down the car. Thought it got a AST error though when it did that, but it's worth a try.
