CMM is not a model number, but since you specified this is an EFI unit and is 7kW, I am assuming this is in the HGJ series.

On that unit, Code 45 is Speed Sense Fault. It means that the controller can not determine how fast the engine is running.

I just noticed that you have 2 questions open for the same problem.

Close this question out, and we can work off the other one.
