Awesome ?? just what I needed. Thank you swoop you are a legend.
hate to tell you but that serial number is not an NR3500
it comes up as a C4000 or C5000 IC truck.
IF in fact this is an NR3500 what voltage is the truck? they made a 24v and a 36v and they both had different control systems in them.
I did find a code 313 in the 24v truck code list and it deals with pump controller:
Short circuit, overload or broken wire at
one of the digital outputs. If this fault
occurs, all the outputs will be disabled.
Only the lower valve can be switched on.
There is also an HPK document out on this code stating:
When error code 313 occurs, the pump functions are disabled. A broken wire or an open has occurred in the hydraulic solenoid electrical circuit.
The resolution is as follows for checking circuits
Check connector XA2 on the pump motor controller for loose connection or loose pins in connector. Check the coil resistance in the hydraulic solenoid circuits. Verify the resistance in the following circuits:
XA2-3:2 and XA2-3:8 - 13Ω XA2-3:9 and XA2-3:3 - 25Ω XA2-3:12 and XA2-3:6 - 28Ω
XA2-3:2 and XA2-3:7 - 13Ω XA2-3:10 and XA2-3:4 - 25Ω
XA2-3:2 and XA2-2:2 - 16Ω XA2-3:5 and XA2-3:11 - 53Ω
Make sure to key OFF the truck and disconnect the battery before taking resistance readings for error code 313. Check resistance across each circuit using a multi-meter. If an open circuit is found, use a 10Ω resistor at the pump connector to simulate the complete circuit. (This is only for the 13 and 16 ohm auxiliary circuits) This will allow the truck to self test and allow you to position the carriage to better troubleshoot the circuit. DO NOT leave the resistor in the circuit! Also, an open in the fan control circuit to the pump controller XA2-4:5 will cause this code.
the code 180 i cannot find.
Going by the layout of the codes it would be a traction controller code but it is not listed.
What i did notice though in this truck code list is traction codes begin with a 1xx, steering controller codes begin with a 2xx, and pump controller codes begin with a 3xx.
hope this helps
