John Deere 523827.14 – SCO: CAN Bus Message Cannot Be Received, Information from E-SCV XIII

Data transfer problem between the control software and the Electro-Hydraulic Selective Control Valve 13 (E-SCV XIII). This typically points to a communication failure on the CAN Bus network or an internal fault within the transmitting control software or the E-SCV stepper motor itself. When this fault is active, the selective control valves will typically have limited functionality or cease to function altogether.

1. 1

   Thoroughly check all CAN Bus wiring leading to the SCO module and E-SCV XIII for signs of physical damage, loose connections, or corrosion.

2. 2

   Use a diagnostic tool (like John Deere Service ADVISOR) to test the CAN Bus network for proper communication and to see if the E-SCV XIII is dropping off the network intermittently.

3. 3

   Ensure that the E-SCV XIII unit is receiving proper supply voltage (a drop below 9 volts can trigger related SCO codes) and is functioning correctly.

1. 1

   Secure and Repair Wiring

   If any damaged wiring, loose pins, or corroded connectors are found during the diagnostic inspection of the CAN Bus harness, repair or replace the affected sections and secure the connections.

2. 2

   Recalibrate the Unit

   If the wiring is intact, attempt to recalibrate the E-SCV XIII control unit via the tractor's diagnostic interface.

3. 3

   Replace the Stepper Motor

   If the CAN Bus network is communicating properly but the E-SCV XIII unit fails recalibration or continues to drop communication, the E-SCV Stepper Motor is likely suffering from an internal failure and must be replaced.

4. 4

   Clear Codes and Test

   After replacing the stepper motor, clear the SCO 523827.14 code, reboot the control system, and test the selective control valves for proper operation.
