NW Iowa | If both hoses have been replaced, it's not the hoses.
You have an open wire someplace.
Unhook that big 36 pin connector and visually check the harness.
After that check the ground side pins and the power pins.
I would also remove the covers on the connectors that go to the hoses and check them.
The ground and hot for those hoses splice in line then go to your power module in box. The power box that controls the ground and power sends it to other things.
Pin 6 and 17 is ground for the pressure and pin 33 is power.
pin 7 and 18 is ground for the suction and return and pin 33 is power
That 33 power splices down stream into about 5 wires one of them going to the pump module.
Sometimes the schematic is off on the grounds, since there are multiple.
Those grounds splice down stream then go to the engine ecm.
But since your not getting more than one code, ( example 5210001 and the 4357)it should be on the specific wire going to those hose sets and not before.
The ground side sends the signal to the ECM not the power, they each have there own ground that goes back to the ecm.
The power side is spliced and runs to multiple things.
Tell him to quit looking at the F ing hoses and use his brain, pull out is multimeter and get a schematic.
The reason its derrating so quick, is the fault is coming up as soon as the key is on. The other day it must have arced and held for awhile or made contact
Does this all make sense?
If your tractor has sat outside a lot or been around rodents, you could fight a lot of these problems
I have a D I bought new it's a '12, and knock on wood I haven't touched anything on the emissions side
They don't give problems, unless someone or something has been poking around stuff.
Keep that pump module and your battery box cleaned out. What yr and how many hrs are on your tractor? | |
