I have missed this. No lights = no software running in ECU. You can also check this observing the main relay - with ignition on, it will click, with ignition off, it will take like 8 seconds to click. When software in ECU is not running, it will click inmediatelly after ignition off.
Possible problems - broken CPU, broken of corruped flash memory or problem between CPU and flash memory. Lot of time, it is because of broken small SMD resistor - they are not the best quality."Drobek" = The Small One - Discovery 2, "Blufínek" = The Blue Thing - Defender 130, and for me at least Ford Mondeo
