Description:

This error code, SCO 520542.03, indicates that the voltage of CAN+ on the vehicle CAN Bus (500 kBd) is too high, suggesting a short to 12 volts. Excessive voltage can damage the CAN Bus components and prevent proper communication.

Reaction:

When this fault is detected, the control software may have limited functionality or may cease to function altogether.

Recommendations:

• Inspect CAN Bus Wiring for Shorts:
  • Check the wiring and connections on the CAN Bus for signs of shorts to 12 volts. Repair or replace any damaged wires.
• Verify CAN Bus Components:
  • Ensure that all CAN Bus components are functioning correctly. Replace any faulty components.
• Check Electrical Connections:
  • Inspect all electrical connections for corrosion, looseness, or damage. Clean and secure connections as needed.
• Monitor Voltage:
  • Continuously monitor the voltage on the CAN Bus to ensure it stays within the recommended range.

Note:

• Preventive Maintenance:
  • Regular inspections of the CAN Bus system can help identify and address potential voltage issues before they cause operational problems.
