BCU 523812.19 – Incorrect CAN BUS Message for Y74 Solenoid, PTO Speed 2. John Deere System Advisory.
John Deere error BCU codesDiagnostic trouble code BCU 523812.19 is triggered when there is a communication error involving the Y74 solenoid for PTO (Power Take-Off) Speed 2. This fault occurs because the output designated for switching the solenoid is erroneously energized by more than one control unit. This can lead to conflicting commands and improper operation of the PTO…
