Master Clutch Potentiometer Open Circuit or Short to Ground
Cause:
The transmission controller has detected that the clutch (inching) pedal potentiometer signal is out of range low.
Possible failure mode:
1. The pedal position potentiometer failure.
2. Wire harness of the inching pedal potentiometer failed open or shorted to ground.
Solution:
The clutch (inching) pedal position potentiometer is mounted on side of the inching pedal and wired to the
transmission controller.
1. Check the pedal position potentiometer and its wiring through the TRANS VIEW / VIEW PEDAL screen
or the service tool.
The clutch pedal position can be viewed in the instrumentation cluster display through the TRANS VIEW/VIEW
PEDAL screen.
It can also be viewed in the monitor screen of the service tool.
If correct, the position display should be 100% when the clutch pedal is fully up and 0% when the pedal is fully
depressed.
The number should smoothly drop as the clutch pedal is depressed.
Watch the display while slowly cycling the inching pedal.
If the number change follows the pedal movement smoothly, the potentiometer and its wiring are working OK.
If the numbers are hard to control or do not fall in sequential order, replace the pedal position potentiometer.
If numbers on display are locked up and will not change when clutch pedal is cycled, check the pedal position
potentiometer and its wiring.
NOTE: There could be an intermittent problem and the tractor may still run, so check for loose connections.
2. Test the pedal position potentiometer and its wiring.
Remove the rear controller cover.
Disconnect connector C351 and C350.
Measure the resistance at the harness side.
The resistance between pin 1 and pin 17 of C351 must increase smoothly as clutch pedal is depressed.
The resistance between pin 1 of C351 and pin 23 of C350 must decrease smoothly as clutch pedal is
depressed.
If the potentiometer does not work as specified above, repeat same testing procedures at connector C010 and
C052.
If the potentiometer does not work as specified above at C052, replace the potentiometer. Otherwise check the
wiring back to the controller.
If the potentiometer is working as specified the problem may be intermittent.
