Hyster J40XM:
Code 02 and 03, no drive hydraulics work

We resealed a Tilt cylinder, the steering cylinder and replaced the steering lines. had to remove the battery and removed counter weight to get new line routed as factory. After reinstalling everything and testing functions everything worked, battery died, gave error 15 on dash display, and after charging we have no forward or reverse. Going forward it will give code 02, and in reverse 03. If you hit the Mono pedal in the same direction a few times it will jump in that direction, give code 15. Have to unplug and plug battery back in to get code to clear, and will show 80 to 100 for battery level after that. It will do this with the motor on one side disconnected, but when both are it gives a code (I think it was 25). I've unhooked both motors at the contactors, the motors and the grounds on the motors to the same results. The right side contactor arcs when the unit jumps, pulled them apart and cleaned them up, same results. We are a construction equipment shop so don't mess with electric lifts too much, any thing you guys can think of to find out what is going on?

Update Time, So Code 02 is Forward Contactors not closing and 03 is same just for reverse. Couldn't find anything too helpful online as far as wiring or codes so I did buy the service manual. After checking wiring and cleaning up the grounds for the drive motors it worked fine. Hope this helps someone out that is stumped and if you need a code for the older A109 models let me know
