Description:

This error code, SCO 521404.19, indicates that the value of the control lever for E-SCV XI cannot be determined and provided on the CAN Bus by the AIC control software. A transmitted replacement value generates this diagnostic trouble code. In its active state, this fault can also generate diagnostic trouble codes at the AIC control software, which take priority.

Reaction:

When this fault is detected, the selective control valve (E-SCV XI) will not function.

Recommendations:

• Inspect CAN Bus Wiring:
  • Check all CAN Bus wiring for signs of damage, loose connections, or corrosion. Secure and repair any issues found.
• Verify AIC Control Unit:
  • Ensure that the AIC control unit is functioning correctly. Recalibrate or replace the unit if necessary.
• Test CAN Bus Communication:
  • Test the CAN Bus network for proper communication and address any faults detected.
• Consult Technical Support:
  • If the issue persists, consult technical support for further diagnostics and assistance.

Note:

Intermittent Issues:

• Intermittent reception can be difficult to diagnose. Regular monitoring and thorough inspection of the CAN Bus system are recommended.
