ABS light on :(

Morning all, a bit of help needed. Just had the abs light come on, recently changed the clutch master and slave and since then light stayed on. Put on diagnostic box at local garage and they came up with 3 faults, not sure if the codes are right as it wasn't a l/r diagnostic box.
codes
1-3 pump running when not switched on-- haven't heard it running after switching off.
1-5 internal ecu fault
1-6 brake switch failure-- all lights work

Any help gratefully received
Thanks
Mike

First try resetting brakelight switch I.E. push pedal down by hand.pull switch pin out using long nose pliers. then let pedal return. this will reset switch

Take it this is a manual. There are two switches one on the clutch pedal to knock cruise control off when changing gear (If fitted). One on the brake pedal which is two pole. One pole is made with brake off one pole is open circuit. When brake is applied these two poles swap senses. The made one opens, the open one makes. If this is not happening you will get ABS fault. Brake switch needs adjusting see RAVE for details of how to do it.

thanks guys, will try this when she gets home with car.
