I have a 1313 series truck with the following two codes: T240 and L314. They will appear out of nowhere. Sometimes sitting still at idle and sometimes while tilting. The truck will still travel but it kills all hydraulic functions. Since Pathfinder has no "Offline Diagnosis" feature for the 1313 trucks I tried looking for the codes on the offline diagnosis under a 392. The codes aren't listed under the 392's and the only thing I can find for them under the 1313 is in "Error Codes+Parameters/Working hydraulics/Trouble code memory" L314 - missing translation. "Error Codes+Parameters/Traction/Trouble code memory" T240 - missing translation. Since the lift driver told me it the first few times it happened he was tilting I figured it was maybe a joystick or tilt angle sensor. I replaced and calibrated the joystick assembly and recalibrated the tilt sensor. It did no good at all. Any help will be greatly appreciated.
