This software update widens the neutral zone window parameter, keeping minor sensor voltage fluctuations from triggering a critical system shutdown. 4. Replace the Tiller Head Board or Control Sensor
When the main logic controller receives a voltage signal that falls outside the preprogrammed parameters (for instance, reading a drive command and a lift command simultaneously that breach reasonable operating windows), it logs .

Under the plastic cover at the lower mast, Marta finds the 3-pin connector (power, ground, signal). One pin is corroded – green oxidation. She cleans it with contact spray and reconnects. Restart – same error. This software update widens the neutral zone window
A technician may need to perform a calibration (Teach-In) to re-map the neutral positions for the steering and travel sensors. Typical Symptoms on the Work Floor Under the
: The "neutral zone" window for the sensors is too narrow, or the sensor itself is failing to return to a true zero point.
