John Deere 002370.05 – FCC / CLC / ICC: RIGH Turn Signal Low Amps

The Cab Load Center (CLC) has detected lower than expected electrical current in the right-hand turn signal circuit. This fault indicates an issue with the low amps function of the Right Hand Side Wide Vehicle Warning Light, Tail Light, and Front and Rear Trailer Sockets. This may result in reduced or failed operation of these components, commonly caused by a failing bulb, high-resistance connections due to corrosion, a broken wire, or a poor ground connection.

1. 1

   Cycle the ignition to determine if the fault code is a temporary glitch

2. 2

   Visually inspect the right turn signal bulb for failure (a rapid flashing dash indicator often points to a burnt-out bulb)

3. 3

   Inspect the wiring harness leading to the right turn signal for visible damage, breaks, corrosion, or loose connections

1. 1

   Replace turn signal bulb

   Replace the right turn signal bulb, even if it does not appear to be visibly burned out, as this is the most common cause of a low amps fault.

2. 2

   Inspect and clean bulb socket

   Check the bulb socket for corrosion or damage. Clean the socket if necessary to ensure a solid electrical connection with the new bulb.

3. 3

   Check circuit fuses

   Locate the fuse box and inspect the fuse related to the turn signal circuit. Replace any blown fuse with a new one of the exact same amperage.

4. 4

   Test electrical circuit

   Using a multimeter, check for voltage at the turn signal socket, verify a solid ground connection, and test for continuity along the wiring harness to identify breaks or shorts.

5. 5

   Inspect flasher or relay

   Check the turn signal flasher or relay. If it is a replaceable component on your specific model, replace it if faulty.

6. 6

   Diagnose control module

   If the issue persists after wiring and bulb checks, the fault may lie within the CLC, FCC, or ICC control module. This typically requires a dealer with specialized diagnostic tools and programming capabilities.
