John Deere 002865.02 – CLC / FCC: Windscreen Wiper Switch Issue

The Cab Load Center (CLC) or Front Chassis Control Unit (FCC) has detected multiple, conflicting, or unexpected electrical signals from the windscreen and/or rear wiper switch. This indicates a circuit fault, pointing to a malfunction in the wiper switch itself or the associated wiring.

1. 1

   Retrieve and document all active and stored diagnostic trouble codes through the command center display to confirm 002865.02.

2. 2

   Cycle the wiper switch on and off, clear the fault code, and see if it returns after operating the switch.

3. 3

   Check the fuse box for any blown fuses related to the wiper system, which could indicate a short circuit in the wiring or a problem with the wiper motor.

4. 4

   Visually inspect the wiper switch for physical damage, loose connections, or corrosion on the electrical terminals.

5. 5

   Determine if other electrical components in the cab are malfunctioning, which could point to a broader electrical issue, such as a problem with the CLC or a main power supply.

6. 6

   Inspect the wiring harness leading to the wiper switch for visible damage, chafing, or loose connectors.

7. 7

   Perform a multimeter test by disconnecting the switch from the wiring harness, setting the multimeter to Ohms (Ω), and probing the terminals while operating it through its various speed settings (an open loop in an 'on' position indicates a faulty switch).

1. 1

   Park Safely

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

2. 2

   Disconnect Power

   Disconnect the negative battery terminal to ensure safety during electrical work.

3. 3

   Access the Switch

   Remove the necessary trim panels to gain access to the wiper switch module. This may involve removing screws and carefully detaching plastic clips.

4. 4

   Perform Diagnostic Tests

   Conduct the diagnostic checks mentioned above, particularly the multimeter tests on the switch and wiring, to confirm the point of failure.

5. 5

   Replace the Faulty Component

   If the wiper switch is determined to be faulty, disconnect the electrical connector and remove the switch from its mounting. Install the new switch, ensuring the electrical connector is securely fastened.

6. 6

   Reassemble

   Reinstall any trim panels that were removed.

7. 7

   Reconnect Power and Test

   Reconnect the battery terminal. Turn the ignition on and test all functions of the new wiper switch (all speeds, washer function, etc.) to ensure proper operation.

8. 8

   Clear Fault Codes

   Clear the 002865.02 fault code from the control unit's memory. Operate the tractor and re-check for any returning codes to confirm the repair was successful.
