John Deere 002362.06 – BLC: High Amps Detected on Rear Roof Inner Work Light Pin

The Main Control Module (BLC) has detected an excessively high electrical current in the circuit for the inner work lights located on the rear of the cab roof. When the current exceeds the predefined safety limit, the module triggers this fault and typically deactivates the circuit to prevent damage to the wiring or the controller itself. This is usually caused by a short to earth, an incorrect high-wattage bulb, or a faulty control module.

1. 1

   Inspect the work light bulbs for internal shorting, damage, or incorrect wattage specifications

2. 2

   Verify that no aftermarket lights or additional accessories have been spliced into the factory wiring, exceeding the circuit's amperage limit

3. 3

   Examine the wiring harness and connectors leading to the rear inner roof lights for chafing, melting, moisture intrusion, or exposed wires shorting to the chassis

4. 4

   Cycle the machine's power to see if a transient electrical issue clears

1. 1

   Turn Off the Tractor and Disconnect Power

   Turn off the engine and disconnect the battery before working on the electrical system.

2. 2

   Access the Rear Inner Work Light(s)

   Locate and access the housing for the inner work lights on the rear of the cab roof.

3. 3

   Remove and Inspect the Bulb

   Remove the bulb from the light assembly. If the bulb is visibly damaged or appears to be the wrong type, replace it with a genuine OEM part or a bulb with the exact same specifications.

4. 4

   Test the Circuit (if necessary)

   If a new, correct bulb does not resolve the issue, use a multimeter to check for a short circuit in the wiring. With the bulb removed, check for continuity between the power wire at the light socket and the tractor's frame/ground. There should be no continuity. If there is, it indicates a short circuit in the wiring harness that must be located and repaired.

5. 5

   Inspect the Light Assembly

   Check the light housing and socket for any internal damage or corrosion that could be causing a short.

6. 6

   Reassemble and Test

   Once the faulty component (bulb, wiring, or light assembly) has been repaired or replaced, reassemble the light, reconnect the battery, and turn on the work lights to verify that the repair was successful and the fault code does not reappear.

7. 7

   Dealer Intervention

   If the fault persists after these steps, the issue may lie within the BLC/VLC control module itself, which would require diagnosis and potential replacement by a qualified John Deere technician.
