Hello.
Need some help with Hitachi Dr.Zx trouble codes reset. I can read MC (machine ecu) trouble codes, but when i try to delete errors says "comm lost"
any idea? What is Retry B? How to access? Is similar to service mode?

Retry B being there is a failure in the Controller.
I would recommend, trying a new controller.

All parts mentioned early are changed. Still same errors. I dont think retry b has to do with broken controller. Retry B is the solution to delete errors. Still cannot access this function. Anyone who can help?
regards.
