Illegal software operation.
After a system reset (e.g. using the ignition key), the system should work normally. • Check for available software updates/campaigns. • Check electrical installation in vehicle for non-certified third party equipment(*) and disconnect these. (*) The sensitivity, for equipment with high EMC radiation, is increased in an EMC emitting environment. This could for example be radar stations (airport/military), electric distribution plants, electrical switch towers, transformer stations, steel works, "electric" welding, etc.
