John Deere 2173.09 – SCO: CAN Bus Message Cannot Be Received, Information from E-SCV XIII

A data transfer problem between the SCO control software and the E-SCV XIII (Electronic Selective Control Valve 13). The expected communication over the CAN Bus network is missing or interrupted, pointing to a failure in the CAN Bus wiring, a loose connection, or an internal fault in the transmitting control software/stepper motor. This results in limited or no operation of the selective control valve.

1. 1

   Inspect CAN Bus wiring harnesses routing to the SCO and E-SCV XIII for physical damage, loose connections, pinched wires, or corrosion at the connector pins.

2. 2

   Verify the E-SCV XIII control unit is receiving proper supply voltage (must be above 9 volts).

3. 3

   Test CAN Bus communication using a diagnostic tool (like John Deere Service ADVISOR) to verify if the SCO module can ping E-SCV XIII.

4. 4

   Perform a wiggle-test on the harnesses while monitoring the CAN Bus status to check for intermittent reception issues.

1. 1

   Secure and Repair Wiring

   If any damaged wiring or corroded connectors are found during the inspection, repair the harness or replace the connector pins. Secure any loose connections.

2. 2

   Reboot the System

   Restart the tractor's control system to reset the software and clear the code.

3. 3

   Recalibrate the Valve

   If the wiring is intact but the code persists, attempt to recalibrate the E-SCV XIII unit via the tractor's command center or diagnostic tool.

4. 4

   Replace the E-SCV / Stepper Motor

   If the E-SCV XIII unit fails recalibration, does not communicate, or has an internal stepper motor failure, the E-SCV valve/actuator must be replaced.

5. 5

   Consult Technical Support

   If the issue persists after replacing the valve, the SCO module itself may require a software flash or replacement.
