1. 1

   Inspect all CAN Bus wiring connected to the SCO and E-SCV XI for signs of physical damage, loose connections, or corrosion.

   Test the CAN Bus network for proper communication signals to isolate whether the fault is network-wide or isolated to Source Address 171.

3. 3

   Verify that the E-SCV XI control unit is receiving power and functioning correctly.

4. 4

   Monitor for intermittent issues by thoroughly inspecting the CAN Bus system for loose pins or chafed wires that fail under vibration.

1. 1

   Secure and repair wiring

   If any damage, corrosion, or loose connections were found during the wiring inspection, repair the harness or secure the connections.

2. 2

   Address network faults

   If the CAN Bus communication test revealed network faults, repair the CAN lines (CAN High / CAN Low) leading to the E-SCV XI.

3. 3

   Recalibrate the unit

   If the wiring is intact but the module is unresponsive or out of sync, attempt to recalibrate the E-SCV XI control unit via the John Deere Service Advisor tool.

4. 4

   Replace the E-SCV unit

   If the E-SCV XI control unit cannot be recalibrated or is confirmed to have an internal hardware failure, replace the unit.
