A friend of mine recently bought a 2017 Iron 883, and it has recently been throwing error codes for the coil and the ECM. They've (the dealership) already replaced them both, and they are now on the second ECM since it started happening. Any Ideas on what it could be?

 

You might get more replies if you post in the Sporty section. Try to include more details about the bike, how it runs, any modifications, especially recent ones & the error code numbers.
