John Deere VLC002388.06 – VLC: Center Point Loop Current Problem

The Vehicle Load Center (VLC) has detected an issue with the electrical current in the center spot light circuit. The '.06' suffix indicates a generic current problem, which could be an over-current (short circuit) or an under-current (open circuit) condition. When this fault is detected, the solid-state VLC controller shuts down the affected circuit to prevent damage and logs the diagnostic trouble code. The circuit will remain off until the operator cycles the light switch.

1. 1

   Check the battery, starter, and all ground connections for tightness and corrosion.

2. 2

   Visually inspect the center spot light bulb for a broken filament or other signs of failure.

3. 3

   Inspect the wiring harness leading to the center spot light for any signs of chafing, pinching, fraying, or rodent damage.

4. 4

   Ensure the electrical connector at the light housing is secure and free of corrosion.

5. 5

   Reset the circuit by turning the light switch to the 'OFF' position and then back 'ON' to see if the code clears and the light functions.

1. 1

   Gain access to the light

   The center spot light is typically located in the front grille of the tractor. Access may require removing a plastic grille cover, which is often held in place by metal clips.

2. 2

   Test the circuit

   If a new bulb does not resolve the issue, further electrical testing is required. This involves using a multimeter to check for proper voltage and continuity at the light's connector and along the wiring harness back to the VLC. This is where the official 'VLC – Center Spot Light Circuit Test' would be utilized.

3. 3

   Replace the bulb

   If the bulb is found to be faulty, replace it with a new one.

4. 4

   Repair wiring

   If wiring damage is found, repair or replace the affected section of the harness.

5. 5

   Clear fault codes

   After the repair, clear any active diagnostic trouble codes.
