The fault are clearing but after a few hours of work thee Tilt linkage position sensor is getting out of calibration again. I just noticed that the Tilt Stops are worn, can this cause the sensor to get out of calibration because of too much bucket tilt?
That might be possible, however I would've thought wear (or something loose) in the sensor operating linkage (or even the pins/bushes in the bucket tilt linkage) would be a more likely cause.
Also the Auto bucket crowding is not working. We have just fitted new sensors but the Tilt is still going out of calibration
If you have ANY Code for the tilt linkage sensor the Tilt Kickout will not work because it depends on a signal from the same sensor.
If I can explain it this way, when you do the calibration the ECM records the minimum & maximum values of the sensor, whatever those values might be. Let's say for example they are 14% min & 87% max. When the machine is working so long as the values registered by the ECM do not go outside that range while the linkage is moving - no problem. If one does (and I don't know by how much the signal has to go outside the calibration range) then the ECM should register an FMI13 Code.
Can you investigate exactly when it is losing the calibration.?
For example does it lose it after the key has been switched off for a while.? Say lunch break, shift change, parked overnight.?
Or does it lose calibration while the machine is operating.?
