Hi guys back with another problem… the machine seems to be loading the pump to much and stalls when hold over relief. Dp sensor seems to be ok sway out angle sensor no difference.. keeps flashing up error code 35? Anyone any info on why it’s flashing this code up

 

[mg2361]

35 = Short circuit in the arm in pressure sensor or it's wiring.

 

[Darreng]

And how does that sensor effect the digger?

Gday Darren,search ABP sensor there is a thread here LACHAU explains it well...
Cheers James

I think James is referring to this one:

Do yous know which wire on the pvc side of the harness is the signal wire coming form this sensor?
I hooked up the multimeter to the signal wire *** from the sensor and it shows 4.9v all the time doesn’t seem to change anything when your operating the machine

Terminal #24

Ok must check this out.. what’s best way to clear the codes to see what comes back up?

 

[mg2361]

Don't know without diagnostic software. The way the codes get cleared is having the diagnostic software plugged into the machine and communicating with the key on, then unplug the diagnostic tool for 1-2 seconds, then plug it back in.

You could try disconnecting the battery and reconnecting. I don't know if that would work to be honest.

 

[Darreng]

Tryed disconnecting the battery but didn’t work.. I just did the same as you said todo with the diagnostic computer but I did it with the the cross wire and it work for me…
Got the digger going again hope it’s stays going now.. I changed one of the displacement valves on the pump. Cleared the codes and the only code that keeps coming up is 35. I Checked the voltage at that ABP sensor and it shows 4.9 volts coming out of the sensor all the time and goes up to 5.1v when bita pressure. When you are grading with the digger and trying to take the bucket in level and u go to raise the boom arm she gets abit jumpy I was woundering is this sensor effecting this?

 

[mg2361]

Probably.

 

[Darreng]

Probably.

Would the volts at the sensor go up with pressure at the sensor or go the other way? It doesnt seem to be the sensor cause I swapped it with the one behind the cab

 

[Darreng]

Terminal #24

You don’t have a digram of the plug on the pvc showing this terminal

 

[mg2361]

Would the volts at the sensor go up with pressure

Yep

You don’t have a digram of the plug on the pvc showing this terminal

I PM"d you
