Hi! I have a Mitsubishi mm30sr with the error code E-22. I have been looking all over to find a user manual, a code chart, a diagnostic manual, a part manual or any other document that could help me use this excavator and repair it when necessary. Any help would be mostly appreciated. Thanks in advance for the consideration you will give to my demand. MITSU
Did you ever get this sorted? Got the same issue now, and I believe it is related to the Interference computer (Bucket swing sensors etc..). The only way I can override so far is to press the red button, but restricts use every time the machine goes off/on and have to push button again and listen to a stupid beep.
