all seems to work on machine, key turns on, system check ok. horn works reverse buzzer works, lights work. steering working....when using hyd levers or attempt to drive, display shows to release levers or pedal. customer has informed that machine just stopped during travel and hasnt moved again in a week. i managed to retrieve two codes a14 , a15 although they were brief an only appeared once. any diag tips or manuals would be appreciated......Niehiyu fbrf14-603-630msf serial no -152ac0195
