Code: 002034.09

Shortcode: 2034.09

Description:

The error code SV2 002034.09 indicates that the Selective Control Valve Unit II (SV II) is not receiving the required messages from the SCC (Selective Control Command). This communication failure can be due to issues in the CAN BUS network, faulty SCC, or disruptions in the SV II unit itself.

Reaction:

When this error code is triggered, the equipment may experience disrupted or erratic operation of the Selective Control Valve Unit II, leading to potential loss of control over specific hydraulic functions.

Recommendations:

Inspect CAN BUS Network:

  • Check the integrity of the CAN BUS network connections and wiring. Look for any signs of damage, corrosion, or loose connections.

Verify SCC Functionality:

  • Ensure that the SCC is operating correctly and sending the necessary messages. Perform diagnostics on the SCC to identify and resolve any issues.

Check SV II Unit:

  • Verify that the SV II unit is receiving power and is properly connected to the CAN BUS network. Perform diagnostics to ensure the SV II unit is functioning correctly.

Update Software:

  • Ensure that the software for both the SCC and SV II unit is up-to-date. Install any available updates to improve communication reliability.

Inspect Wiring Harness:

  • Examine the wiring harness for any signs of wear, damage, or shorts that could affect communication.

Note:

Regular maintenance and inspection of the CAN BUS network and related control units are essential to prevent communication failures. Ensuring all components are in good condition and operating within manufacturer specifications can help avoid issues with missing messages.

By following these steps, you can effectively diagnose and rectify communication issues to ensure the proper operation of the Selective Control Valve Unit II and overall equipment reliability.
