Symptom

Diagnosis & fix steps

Check the harness under the steering column. 80% of these failures are caused by wires rubbing against the steering tilt mechanism.

Red Seal field insights

Pro-Tip: If the wiring is intact, the internal micro-switches in the Shifter Stalk are likely worn. Red Seal Fix: Try switching to the "CDC" (Comfort Drive Control) joystick shifter if equipped. If the machine moves using the joystick but not the steering column stalk, you’ve confirmed a dead stalk.
