FAULT CODE TRANS 60
FNRP pod in illogical state (in no position)
Cause:
If FNRP pot indicates not in neutral, not in forward, and not in reverse for 2.5 seconds, the transmission controller
will record this fault code.
Possible failure modes:
For NH8: 1. The FNR lever may be stuck in between positions.
For MU8: 1. The operator may be holding the lever up for too long.
2. The transmission control (FNRP) pot failure
3. Wiring harness problem from the transmission control (FNRP) pot to the transmission controller.
Solution:
The transmission control (FNRP) pod is directly wired to the transmission controller. The transmission controller
monitors the shuttle shifting and displays the shuttle position on the instrumentation cluster.
1. Make sure the operator is not holding the lever up for too long.
2. Troubleshooting by viewing the shuttle position display.
In some cases, problems can be detected by viewing the display while shifting the transmission control (FNRP)
lever.
Turn Key 'ON' and watch the shuttle position display.
If Forward icon does not lit up on display when in Forward, either the Forward switch failed open or its wiring
shorted to ground.
If Reverse icon does not lit up on display when in Reverse, either the Reverse switch failed open or its wiring
shorted to ground.
If Neutral icon does not lit up steady when in Neutral or Park, either the Neutral switch failed closed or its wiring
shorted to power.
3. Troubleshooting by checking FNRP switch function.
Disconnect the cover panel under the steering column. Locate connector C051. Measure continuities on the
transmission control (FNRP) pot side.
Measure between Pin 6 (Forward) and Pin 8 (5 Vref), there should be about 500 - 600 Ohms when in Forward
position and about 2500 - 3000 Ohms when in other positions. If not, the Forward switch failed.
Measure between Pin 5 (Reverse) and Pin 8, there should be about 500 - 600 Ohms when in Reverse position and
about 2500 - 3000 Ohms when in other positions. If not, the Reverse switch fails open.
Measure between Pin 7 (not Neutral) and Pin 3, there should be no continuity in Park or Neutral position and there
should be continuity in Forward or Reverse positions. If not, the Neutral switch failed.
NOTE: Neutral switch off indicates tractor is in Neutral. Neutral switch on indicates tractor is not in Park.
If any above switch failure is detected, replace the transmission control (FNRP) pot.
If no switch failure is detected, go to next step.
4. Check the wiring from connector C051 to the transmission controller.
Check the wiring from connector C051 to connector C351 on the transmission controller.
