TROUBLESHOOTING
8.1 TRACTION CONTROL SYSTEM (TCS) __________________________________________
The Traction Control System (TCS) is designed to protect the electrical components of the traction and battery
systems. An error code is displayed when a fault condition occurs.
In most instances the traction controls on the tractor will cease to operate when an error condition occurs.
In some cases resetting the TCS will allow the tractor to be restarted and operation resumed. If an error code continues
to occur after resetting the TCS, the tractor should be shut down and returned to a service area for inspection.
Error conditions caused by an electrical problem should be inspected and repaired by an experienced mechanic
familiar with the electrical system of this machine.
