Reaction of the control software: No function of the selective control valve.

SCO 521404.19 — Incorrect CAN Bus Message, Information from AIC Control Software
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.
