John Deere 002368.05 – CLC / RLC / ICC: Left Front Turn Signal Low Amps

The Cab Load Center (CLC) has detected lower than expected electrical current (under 0.5 amps) in the left turn signal circuit. This low current condition indicates an open circuit or high resistance, preventing proper electrical flow to the left turn signal bulb.

1. 1

   Perform a visual inspection to see if the left front turn signal illuminates when activated

2. 2

   Check the bulb by swapping it with a known good bulb from the right turn signal to see if the fault follows the bulb

3. 3

   Inspect fuses in the load center (often located behind the operator's seat) related to the lighting circuits

4. 4

   Inspect the wiring harness and connections leading to the left front turn signal for breaks, chafing, or corrosion, paying close attention to the lamp connector and chassis harness connection

5. 5

   Clear the diagnostic trouble codes and operate the turn signal to see if the code reappears as an active fault

1. 1

   Replace the bulb

   If the bulb is found to be faulty or blown, replace it with a new one of the correct type and wattage. This is the most frequent and simplest solution.

2. 2

   Repair wiring and connections

   If wiring damage is found, repair the affected section. This may involve splicing in a new piece of wire with sealed connectors or repairing a damaged pin in a connector. Ensure all connections are clean and secure.

3. 3

   Verify control module configuration

   If the bulb and wiring are good, use a John Deere service tool to verify the lighting configuration stored in the Cab Load Center (CLC) matches the physical lighting package. Incorrect configuration can trigger a low current fault.

4. 4

   Test and replace turn signal switch

   Test the turn signal switch assembly in the steering column for continuity and voltage at its connector pins. Replace the switch assembly if found to be faulty.

5. 5

   Update or replace control module

   If all other steps fail, have a dealer check for software updates. If an internal fault is diagnosed, replace the affected control module (CLC, RLC, or ICC).
