I have a Nissan TN01L15HV S/N TN01-710292 that has been in our shop since I came to work here and now it is my turn to get it working. I tested out the systems on the truck( drive both directions and lift. tilt and side shift) all worked but the hydraulic system had a bad cavitations. I found the problem at the suction hose that had been pinched of by a bad operator. Fixed that but now I have no travel, I am getting two different codes from the two controllers the one the drivers right has a code 34 and the one on the divers left has a code 13. I do not have a manual or schematic for this truck. can anyone help with the codes. Thanks for any help.
