went to look at forklift. driver stated he went into reverse and then nothing was working on the forklift. was able to find an issue with one of the brake sensors that brought back all functions besides forward and reverse. was able to get into tow mode to get back inside warehouse. where can i find an access code for the service side of the computer on the dash? and any help of what else i can do. im thinking it may just need a reset but not to familiar with these yet.
