1. 1

   Restart the tractor to see if the code is a temporary communication glitch

2. 2

   Cycle the front wiper switch through all settings (ON/OFF, different speeds) to see if the code persists

3. 3

   Inspect fuses related to the wiper circuit, specifically checking fuse F22 if applicable to your model

4. 4

   Check for custom accessories (e.g., extra lights) that might be overloading the CLC and remove them to test

5. 5

   Inspect the wiring harness and connections leading to the front wiper motor for loose or corroded terminals

1. 1

   Restart and test system

   Restart the tractor and cycle the wiper switch through all speeds to determine if the fault is active or a temporary glitch.

2. 2

   Inspect and replace fuses

   Check the wiper circuit fuses (including F22). Replace any blown fuses and retest the wiper system.

3. 3

   Isolate aftermarket accessories

   Disconnect any custom accessories added to the CLC circuit to ensure they are not causing an electrical overload.

4. 4

   Repair wiring

   If wiring or connections to the front wiper motor are loose or corroded, clean and repair the harness as needed.

5. 5

   Replace front wiper motor

   If fuses and wiring are intact but the high-speed circuit still draws abnormal current, replace the defective front wiper motor.
