CLC 002863.02 – Simultaneous Activation Fault in Front Wiper Switch. John Deere System Alert.

CLC 002863.02 (CLC 2863.02)

Code: 002863.02

Shortcode: 2863.02


This code is triggered when two inputs (low, high, or intermittent) of the front wiper switch are activated simultaneously for longer than 0.5 seconds. This could indicate a fault in the switch assembly or wiring, potentially leading to erratic wiper operation or failure.


The front wipers may behave unpredictably, potentially impacting visibility during adverse weather conditions.


  • Inspect Wiper Switch and Connections: Examine the wiper switch for mechanical faults and check the wiring for short circuits or loose connections.
  • Replace Faulty Switch if Needed: If the switch is found to be defective, replace it to ensure proper functionality.
  • Functional Testing: Conduct a series of operational tests to verify that each wiper setting functions independently and correctly.


Ensuring the proper functioning of wiper systems is essential for maintaining clear visibility and safe operation in varying weather conditions.
