John Deere 002382.05 – RLC: Clearance Light Circuit Low Amps

The Roof Lighting Control Unit (RLC) has detected lower than expected electrical current (low amps) on the Side Light/Park Light pin when the work lights are turned on. This clearance light circuit fault typically signifies a break in the electrical circuit or a failed component. The most common cause is a blown bulb, but it can also result from high resistance in a connector due to corrosion, a poor ground connection, or a break in the wiring harness.

1. 1

   Perform a bulb test by starting the engine and verifying if the clearance light illuminates for approximately one second

2. 2

   Visually inspect the clearance/side marker light for obvious damage, cracked lenses, or water ingress

3. 3

   Check the relevant lighting circuit fuses to quickly rule out a blown fuse

4. 4

   Check for other active lighting-related fault codes that might indicate a broader RLC or main power/ground issue

5. 5

   Cycle the key switch off and on to see if a minor electrical fault clears

1. 1

   Secure machine

   Turn off the tractor, remove the key, and engage the parking brake before beginning any electrical diagnosis or repair.

2. 2

   Inspect and replace bulb

   Access the faulty clearance light by removing the lens cover or fixture. Remove the bulb and visually inspect the filament. If broken (the most common cause of this fault), replace the bulb.

3. 3

   Clean the socket

   Inspect the electrical socket for green or white corrosion. Clean the contacts with electrical contact cleaner and ensure they make a firm connection with the bulb.

4. 4

   Test for voltage

   If a new bulb does not illuminate, use a multimeter to check for voltage at the socket with the lights switched on. If there is no voltage, the issue is upstream in the wiring or RLC. If there is voltage but no light, suspect a bad ground.

5. 5

   Inspect wiring and connectors

   Trace the wiring harness from the light back toward the cab. Look for chafing, pinched wires, or damage. Disconnect multi-pin connectors, inspect for corrosion, clean with contact cleaner, and reconnect securely.

6. 6

   Check ground connection

   Ensure the light's mounting bracket is clean, free of paint and rust, and that the mounting bolts are tight, as most tractor lights ground to the chassis through this bracket.
