configuration error is commonly displayed on initial ignition power up if a particurlar ecu chassis number/code isnt recognised by the vehicle,on its primary boot up cycle.this can be caused by several variants...welding with no chassis protection,inconsistant connect/disconnect of ecu.s when powered up,slave starting incorrectly(reverse polarity/spike).but ,most importantly back to basics...check feeds,and earths,and plug connections.no control unit will function with out either of these.if feeds,earths,and connections good,then general rule is ecu reprogram by daf.do u have any other script on display,i.e engine warning,alternator warning,abs truck?
