When hdc fault shows car will not crank over. Clear fault memory and car starts and drives fine until a few miles later speedo goes off , abs light and brake light comes on.
Can bus will not communicate with abs module, actronics say original is unrepairable, so got a second hand one but cannot clear donor cars vin number to program to car! Does anyone know any way around this or where to buy a virginized module to program ?!?! Landrover want £1600+vat for a new module!!!!

The only time I have seen HDC message was when battery voltage had dropped. Check voltage and clean up all earths, it may be something silly.
