Hi guys.. Yest whilst trying to change the rear brake pads on my 2012 Avensis Luna I hit the wrong button on my new Foxwell EPB tool and deleated the zero point callibration for the clutch sensor it seems as I have got the following error and cant get it to clear 'C1346 Zero Point Calibration of Clutch Stroke Sensor Undone'. As it stands the electric park brake will work by manually switching it on and off but no longer work in automatic mode and 'Check parking brake' error message flashing
