New Holland TRANS 2071 – Transmission Control Unit (TCU): Forward switch input from the FNRP Pod is shorted to ground or is open circuit

The FNRP (Forward/Neutral/Reverse/Park) pod is the shuttle lever assembly mounted on the steering column. The transmission controller is detecting that the electrical circuit specifically for the "Forward" position switch is either broken (open circuit) or has a path directly to ground (shorted).

1. 1

   Rapidly cycle the FNRP shuttle lever through all positions to free up potentially stuck switch contacts

2. 2

   Try driving the tractor in Reverse to isolate the problem strictly to the forward switch circuit

3. 3

   Shift the lever and watch the instrumentation display to see if the controller registers any movement

4. 4

   Inspect the wiring harness from the FNRP pod down the steering column to the transmission controller for pinched wires, chafing, or disconnected plugs
