BIF 522426.09 – Communication Error in Rear Window Wiper Relay Control. John Deere System Advisory.
BIF 522426.09 (BIF )
Code: 522426.09
Shortcode:
Description:
Error code BIF 522426.09 is reported when there is a disruption in the data communication between the Power Module (HF) PC6 and the BIF control unit, specifically affecting the K06/05 or K02/05 relay for the rear window wiper. This fault occurs due to intermittent or nonexistent reception of CAN messages from the BIF to the power module, which may be caused by loose wiring or other connectivity issues.
Reaction:
The malfunction in communication may lead to improper functioning of the rear window wiper system, including erratic behavior or failure to operate when activated.
Recommendations:
- Inspect and Secure Wiring Connections: Check all wiring connections between the BIF control unit and Power Module (HF) PC6, ensuring they are tight and free from corrosion or damage. Repair or replace any faulty wiring.
- Test CAN BUS Network: Utilize diagnostic tools to examine the integrity and functionality of the CAN BUS network, specifically the segments connecting the BIF to Power Module (HF) PC6. Look for disruptions or errors that could be affecting communication.
- Update Firmware and Software: Verify that the firmware of the power module and the software of the BIF are up to date. Software updates can often resolve compatibility issues that might be causing communication errors.
- Evaluate Power Module and BIF Functionality: Test both the Power Module (HF) PC6 and the BIF control unit to ensure they are functioning correctly and capable of sending and receiving accurate CAN messages.
- Comprehensive Diagnostic Evaluation: Perform a full diagnostic check to identify and rectify any less apparent issues within the communication system that might be causing the data transfer problems.
Note:
Ensuring robust and reliable communication between the power module and the BIF control unit is crucial for the effective operation of the rear window wiper and related systems. Regular checks and maintenance can prevent communication failures, thereby enhancing the reliability and safety of the vehicle’s electrical systems.
