1. 1

   Acknowledge the code on the CommandCenter display and restart the tractor's engine to rule out a temporary communication glitch.

2. 2

   Visually inspect the left brake pedal switch/sensor for physical damage.

3. 3

   Inspect the wiring harness and electrical connector leading to the left brake pedal switch for defective, disconnected, or corroded wiring.

4. 4

   Test the left brake pedal switch/sensor for proper voltage and continuity to determine if the sensor itself has failed internally or if the issue is strictly wiring-related.

1. 1

   Prepare machine

   Park the tractor on a level surface, engage the parking brake, and turn off the engine.

   If the wiring is intact but the sensor failed diagnostic testing, remove the mounting hardware securing the left brake pedal switch/sensor.

7. 7

   Install sensor

   Install the replacement left brake pedal switch/sensor and secure it with the mounting hardware.

8. 8

   Reconnect connector

   Reconnect the electrical connector, ensuring it clicks firmly into place.
