Electrical Problem showing on screen and throttle control not working. Except on manual. I already replaced ECU and throttle motor driver. They were both getting hot. I had been looking for a short no success . I don't have a manual. Can someone help ?
a 902B is a wheel loader ,what is your serial number?
If you mean a 9020B Case Excavator the electrical error is usually the throttle out of calibration. A seized cable can cause this, miss adjusted cable. After replacing you have to do a calibration through the dash. I can help but if it's a 902 wheel loader sorry can't help.
Yes I'm sorry it is 9020b. And yes I need your help to calibrate.
Here is the calibration procedure
