BIF 522434.05 – Open Circuit Fault in Windshield Wiper System (Slow Wipe). John Deere System Advisory.

BIF 522434.05 (BIF )

Code: 522434.05

Shortcode:

Description:

Error code BIF 522434.05 is reported when the Power Module PC0 detects abnormally low current, specifically less than 350 mA, at the output for the windshield wiper (lead 2035) while the switch is set to the slow wipe setting. This diagnostic trouble code suggests an open circuit in the wiring or connections, preventing adequate current flow needed for the operation of the windshield wiper.

Reaction:

Due to this open circuit, the windshield wiper may fail to operate when switched on, which could significantly impair visibility during adverse weather conditions.

Recommendations:

  • Inspect Wiring and Connectors: Check the wiring and connectors associated with lead 2035 for any signs of disconnection, damage, or wear that might be causing the open circuit.
  • Test for Continuity: Use a continuity tester to check the continuity of the circuit. This will help identify where the circuit is broken or open.
  • Repair or Replace Faulty Wiring: If a break or disconnection is found within the circuit, repair the damaged section or replace the faulty wiring to restore proper function.
  • Check Wiper Motor and Relay: Ensure that the windshield wiper motor and any associated relays are functioning correctly and are properly connected.
  • Reset System and Test Operation: After any necessary repairs are made, reset the system to clear the diagnostic code. Test the windshield wiper operation to ensure it functions correctly at the slow wipe setting.

Note:

Regularly inspecting and maintaining the windshield wiper system is essential to ensure safety and operational readiness, especially under inclement weather conditions. Addressing any signs of malfunction promptly can help avoid visibility issues while driving, thereby enhancing safety and comfort for the vehicle’s operator and passengers.
