Traction Control System (TCS) - Test
Note: This procedure determines if the Traction Control System (TCS) is functioning. This procedure also determines if the left rear brake and the right rear brake activate at the correct time.
- Find a clear area and a level area. In this area, turn the machine in a complete circle. Start the machine and move the transmission direction and speed control lever to the first gear Forward.
- Turn the steering wheel all the way to the left. With the engine at low idle, drive the machine in a complete circle.
