Description:

This error code, SIC 002033.09, is generated when there is a data transfer problem between the Body Control Unit (BCU) and the SIC control unit. This issue indicates that the messages required for the operation of the ESCV (Electro-Hydraulic Section Control Valve) / EICV (Electro-Hydraulic Integrated Control Valve) control unit are intermittent or nonexistent, which may be due to a loose wire or other communication issues.

Reaction:

When this error code is detected, the communication between the BCU and SIC is compromised, leading to malfunctioning or incorrect operation of the ESCV/EICV control units. This may result in reduced or impaired hydraulic functions.

Recommendations:

• Inspect CAN BUS Wiring:
  • Check the wiring between the BCU and SIC for any signs of damage, wear, or corrosion. Repair or replace any compromised sections.
• Check Connectors:
  • Ensure all connectors between the BCU and SIC are properly seated and free from corrosion or debris.
• Test CAN BUS Network:
  • Use diagnostic tools to test the CAN BUS network for any faults or high error rates.
• Check for Loose Wires:
  • Specifically look for any loose wires that might cause intermittent communication issues.
• Update Software:
  • Ensure that both the BCU and SIC have the latest firmware and software updates installed.
• Monitor Communication:
  • Use diagnostic equipment to monitor the communication between the BCU and SIC for any intermittent issues or error messages.

Note:

Data transfer problems between the BCU and SIC can lead to significant performance issues. Regular inspection and maintenance of the CAN BUS network and associated components are essential. If the problem persists, consult technical support for further diagnosis and repair.
