John Deere 516451.19 – Rear Chassis Module (SCC): CAN BUS Message Fault Rear Chassis (SCC) / SCV XV Control Lever Fault Message Received

Communication failure on the CAN BUS network where the module is receiving an invalid or faulty message from the Selective Control Valve (SCV) control lever or implement.

1. 1

   Check for Related Voltage Codes: Verify if the SCC is receiving proper power. Look for concurrent codes such as 000158.04 (Low Ignition Supply to Rear Chassis Module) or 000158.03 (High Ignition Supply to Rear Chassis Module).

2. 2

   Check for Software Incompatibility: Verify if code 516457.14 (Incompatible Controller Software / SCC Software Issue) is present, which would indicate a programming mismatch rather than a hardware failure.

3. 3

   Access Stored Codes: Run the 'SCC 001 — Control Unit Stored Codes' test via the diagnostic display to see if the SCV XV Control Lever command is entirely missing.

4. 4

   Harness Inspection: Inspect the Rear Chassis Harness, specifically the interconnects between the cab and the rear chassis (e.g., the X100 Rear Cab Interconnect plug to Rear Chassis Interconnect receptacle).

1. 1

   Inspect CAN BUS Wiring

   Locate the Rear Chassis Harness and trace the CAN BUS communication lines between the SCV XV control lever and the Rear Chassis Module (SCC).

2. 2

   Check Connectors

   Disconnect and inspect the X100 Rear Cab to Rear Chassis interconnects for pushed pins, moisture, or corrosion. Clean and reconnect.

3. 3

   Software Calibration

   If the module software was recently updated or replaced, perform an SCC Calibration/Configuration to ensure the SCV control software is communicating properly with the armrest/cab modules.

4. 4

   Component Replacement

   If wiring and software are intact, the fault lies within the hardware generating the faulty CAN message. Replace the SCV XV Control Lever or the Rear Chassis Module (SCC).
