Xj6nTrav

Hey everyone, just trouble shooting here. Bike (09 xj6n) has been working fine no issues at all and now this happens when I switch ignition on. Error code ER_1 and shows temperature and engine warning lights! The speedo doesn't change from 0 while riding aswell since this code has shown up. Anyone every had this?I've read it may be something to do with ecu. Where should I start? Thanks in advance, any help would be great
