1. 1

   Visually inspect the wiring harness running from the Engine ECU to the Burner Dosing Valve (DV2) for chafed insulation, melted wires, or pinch points.

2. 2

   Disconnect the plug at the DV2 valve and the ECU to check for water intrusion, corrosion, or bent pins.

3. 3

   Use a multimeter to test the DV2 circuit for continuity to battery voltage with the key ON (engine off).

4. 4

   Test the internal resistance of the Burner Dosing Valve itself to determine if the internal solenoid is shorted.

1. 1

   Power Down

   Turn off the tractor and disconnect the negative battery cable to prevent electrical spikes.

2. 2

   Locate the Valve

   Locate the Burner Dosing Valve (DV2) mounted on or near the exhaust aftertreatment burner assembly.

3. 3

   Disconnect

   Unplug the electrical connector from the DV2 valve.

4. 4

   Harness Repair

   If the diagnostic tests revealed a short in the wiring, repair the damaged section of the harness or replace the harness segment.

5. 5

   Valve Replacement

   If the valve itself is internally shorted, unbolt/unscrew the DV2 valve from the burner unit. Be prepared to catch a small amount of residual diesel fuel.

6. 6

   Installation

   Install the new Burner Dosing Valve and torque to OEM specifications. Reconnect the electrical harness.

7. 7

   Clear and Test

   Reconnect the battery. Use a diagnostic tool (such as Deutz SerDia or a compatible Jaltest scanner) to clear Code 60 / SPN 523911. Run the engine and initiate a stationary DPF regeneration to verify the burner ignites and the dosing valve operates without throwing the code.
