engine management light.02 WRX bugeye
 

just replaced the the radiator on my 02 wrx bugeye impreza.no real problems removing and replacing,apart from the hose clamps where all seized on and had to cut them off.all filled up and burped spot on fans working.but then i noticed when i got back from a ride round.the engine management symbol was on and stayed on.would be extremely grateful for any help.

Bit of a random one that, I think you'll need a fault code read on there, it's possible you may have disturbed something while working.
