OIC 520542.03 – CAN Bus +, Voltage Too High
OIC 520542.03 (OIC 542.03)
Code: 520542.03
Shortcode: 542.03
Description:
This error code indicates that the voltage of CAN+ is too high, suggesting a short to 12 volts.
Reaction:
The control software may function in a limited capacity or not at all, affecting CAN Bus communication and overall vehicle operation.
Recommendations:
Inspect CAN Bus + Connections:
- Check the wiring and connections of the CAN+ lead for signs of damage, loose connections, or corrosion. Repair or replace any faulty components.
Test Voltage Levels:
- Use a multimeter to measure the voltage of the CAN+ lead. Ensure it remains within the specified range. If it is too high, investigate the power source for faults.
Check for Shorts:
- Inspect for any short circuits to 12 volts along the CAN+ wiring. Repair any identified shorts.
Update Control Software:
- Ensure that the control software is updated to the latest version. Firmware updates might include improvements in handling CAN Bus voltage levels.
Consult Manufacturer Support:
- If the issue persists, consult technical support or the manufacturer for further diagnostics and assistance.
Monitor System Performance:
- After addressing the issue, monitor the system to ensure the CAN+ voltage remains within the specified range and the error does not recur.
Note:
Maintaining proper voltage levels in the CAN Bus is crucial for reliable communication. Regular checks and maintenance can prevent voltage-related issues.
