John Deere 002360.06 – BLC / CLC: High Amps on Rear Fender Work Light

The control module has detected an abnormally high electrical current in the circuit for the rear fender work light. This condition is typically triggered when the work lights are activated and is most often caused by a short circuit to ground or a faulty bulb, such as a halogen bulb failing in a way that creates an internal short.

1. 1

   Check the work light bulb, as a faulty or incorrect bulb type (especially halogen) is the most frequent cause of current issues.

2. 2

   Visually inspect the rear fender work light for physical damage, cracked lenses, or water ingress.

3. 3

   Inspect the wiring harness leading to the light for visible damage, chafing, or corrosion.

4. 4

   Remove any non-factory accessories tied into the lighting circuit that may be overloading the system.

5. 5

   Perform a functional check by clearing the code and activating the light to see if the fault returns immediately.

6. 6

   Conduct a voltage drop test at the light to identify high resistance or a short in the wiring loom.

1. 1

   Prepare machine for service

   Lower all equipment to the ground, stop the engine, remove the key, and disconnect the battery ground strap.

2. 2

   Access the bulb

   On cab models, pry off the screw cover. Remove the retaining ring screws and the retaining ring or lens to access the bulb.

3. 3

   Replace the bulb (Bulb fault cause)

   Disconnect wiring connectors and remove the old bulb. Install a new bulb of the correct type and wattage. If using a halogen bulb, do not touch the glass with bare hands.

4. 4

   Test the circuit

   Temporarily reconnect the battery and turn on the work light. If the fault code does not return, the faulty bulb was the issue. Reassemble the light housing.

5. 5

   Troubleshoot short circuit (Wiring fault cause)

   If the new bulb does not fix the issue, the fuse blows, or the code returns immediately, disconnect the light assembly. Use a multimeter to test continuity between the light's power wire and a known good chassis ground. If continuity exists, trace the harness to find and repair the short, paying close attention to pinched or rubbed areas.

6. 6

   Replace control module (Module fault cause)

   If all circuit and component tests pass but the code persists, the BLC or CLC control module may be the source of the issue and require replacement as a last resort.

7. 7

   Final assembly

   Reassemble all components, reconnect the battery, and clear any stored diagnostic trouble codes.
