John Deere VLC002356.06 – VLC: Front Floodlight Internal Current Problem

The Vehicle Load Center (VLC) has detected that the current in the front inner floodlight circuit is above the normal operating range. This indicates a potential short circuit to ground or the use of incorrect, high-draw components (such as incompatible aftermarket accessories), which affects the proper operation of the front floodlight.

1. 1

   Acknowledge and cycle power by restarting the tractor to see if the code clears

2. 2

   Check for and remove any aftermarket accessories or non-standard lights added to the front floodlight circuit

3. 3

   Visually inspect the front inner floodlight, wiring harness, and connectors for burnt-out bulbs, cracked or frayed wires, and corroded or loose connections

1. 1

   Disconnect power

   Ensure the tractor is turned off and the battery is disconnected before performing any electrical repairs.

2. 2

   Inspect and replace bulb

   Replace the front inner floodlight bulb with a new, correct-specification OEM or equivalent part, even if it does not appear visibly damaged.

3. 3

   Test the circuit for shorts

   Disconnect the harness from the floodlight and the VLC. Use a multimeter set to Ohms to test for continuity between the power wire and the tractor chassis. A reading near zero indicates a short to ground. Inspect the harness for rubbed insulation.

4. 4

   Check connectors

   Inspect all electrical connectors in the circuit for corrosion, moisture ingress, or pushed-out pins. Clean and repair as necessary.

5. 5

   Test the light housing

   With the light disconnected, check for continuity between the power and ground terminals on the light fixture itself to rule out an internal short.

6. 6

   Diagnose VLC module

   If the bulb, wiring, and light fixture are confirmed good, the fault may lie within the Vehicle Load Center (VLC) module. Contact a John Deere technician for advanced diagnostics and resolution.
