John Deere 2370.05 – CLC, RLC, ICC, or FLC: Right Turn Signal Lights Current Below Normal or Open Circuit

The current for the right turn signal lights is below normal or there is an open circuit. This means the right turn signal output is low, shorted to the battery/power, or there is a physical break in the circuit.

1. 1

   Visually inspect the right turn signal light bulb(s) to see if the filament is broken or burnt out

2. 2

   Cycle the key switch or tractor power to see if a temporary voltage glitch clears the code

3. 3

   Check the right turn signal circuit wiring for open circuits, breaks, or shorts to the battery

4. 4

   Check the implement harness connections and fuses, especially if towing an implement

1. 1

   Replace the Bulb

   Access the right turn signal housing and remove the bulb. If it is burnt out, install a new bulb.

2. 2

   Clear the Code

   Turn the machine's key switch off, then back on to cycle the power. Check the CommandCenter display to see if the 002370.05 code has cleared.

3. 3

   Inspect the Wiring Harness

   If the code still exists after replacing the bulb, trace the wiring harness for the right turn signal. Look for chafed wires, disconnected plugs, or corrosion at the sockets that could cause an open circuit or a short to power. Repair any damaged wiring.

4. 4

   Dealer Module Repair

   If the bulb is good, the wiring is intact, and the code persists after cycling the power, the fault likely lies within the control module (CLC, RLC, or ICC). Have a John Deere dealer repair the module at the earliest convenience.
