Did you change the ecu ? What was the result .ive currently cut the feed to the ECU which is the red/blue wire and took the red/blue relay wire right to ground so that i can run my rhino. Still ends up with the code 43 showing and the engine light on but atleast i can drive it. Still not sure what tells the ecu to put the relay to ground. everything else on the unit works so i guess the ECU must be bad?
