BobCat 753 – ADVANCED HAND CONTROL (AHC) SYSTEM – Troubleshooting Guide

The Advance Hand Control System (AHC) has a built-in diagnostic function which uses an icon on the right instrument panel to indicate the condition of the AHC System. The system also records the alarm condition as a service code.

The control module continually checks the system in the order listed. The checks start with the lift handle controller and then the lift actuator. If no problems are present, it will then check the tilt handle controller and the tilt actuator. The system will stop its check at the first problem and then luminate the icon.

The system starts its diagnostics and calibration when the ignition key is turned ON.

The following list shows the probable causes when the icon is luminated.
