hi all this is baffling me, been looking all over the net and still non the wiser atm.. bought the vxr as a non runner put new engine in the car and it runs sweet as a nut but ive got traction control light on and ids the suspension one.. only error codes ive got is

U2105-71 Invalid Data from ECM (Engine Control Module)

U2105-00 CAN-Bus No Communication with ECM (Engine Control Module

the car was remapped 2k before last owner killed the engine hence ive fitted a replacement which starts sweet but want these other lights off so I can MOT the car as it hasn't seen the road in 2 years..

bugging me now just wondered if anyone else has had same issue... if I search that most people get no communication with ecm mine says invailid data from ecm

cheers in advance steve

have got odd wheel on back atm and a snapped rear spring but I cant seem to read the abs ecu wont let me look at it.. very strange cheers steve
