John Deere 2167.09 – SCC: SV VII Message Missing

The Selective Control Unit (SCC) is not receiving the required CAN bus communication messages from Selective Control Valve VII (SV VII). This condition is typically caused by a break in the CAN bus communication link, faulty wiring, or an internal failure of the SV VII module itself. As a safety reaction, when this code is detected, the SCC will disable its functions to prevent further hydraulic or operational issues.

1. 1

   Inspect the SV VII Unit to verify if it is functioning or broadcasting its own internal error codes

2. 2

   Inspect all wiring harnesses and connectors between the SCC and SV VII for signs of physical damage, corrosion, moisture, or loose pins

3. 3

   Test the CAN bus communication lines for continuity and proper resistance (typically 60 ohms across CAN High and CAN Low with the battery disconnected)

4. 4

   Ensure both the SV VII and the SCC have the latest firmware and software updates installed

1. 1

   Connect Diagnostic Tool

   Hook up John Deere Service ADVISOR to read all active and stored codes. Confirm if the SCC is the only module losing communication with SV VII, or if the entire CAN bus is down.

2. 2

   Visual Inspection

   Locate Selective Control Valve VII at the rear hydraulic block. Inspect the electronic connector located at the front of the valve.

3. 3

   Clean and Reseat

   Disconnect the SV VII harness. Clean the contacts with electrical contact cleaner, check for pushed-back pins, apply dielectric grease, and securely reconnect it. Clear the code and test the machine.

4. 4

   Harness Testing

   If the code returns, use a multimeter to verify power, ground, and CAN High/CAN Low continuity from the SCC to the SV VII connector. Repair any broken wires or shorts in the harness.

5. 5

   Replace the Valve/ECU

   If the wiring is intact and power/ground are present, the electronic control unit on SV VII has failed. Replace the Selective Control Valve or its attached ECU.

6. 6

   Calibration

   After installing a new SCV, use Service ADVISOR to perform the SCV configuration and calibration procedures (e.g., flow rate settings, detent time settings).

7. 7

   Final Test

   Clear all fault codes and operate the hydraulic functions for SV VII to ensure the code does not return and the valve responds correctly.
