John Deere 002370.06 – CLC: Right Hand Lighting Circuit High Amperage

The Cab Load Center (CLC) has detected an abnormally high electrical current (amperage) in the right-hand lighting system circuit. This circuit includes the right turn signal, tail light, wide vehicle warning light, and front/rear trailer sockets. This condition is typically caused by a short circuit to ground or a faulty component drawing excessive power.

1. 1

   Inspect the right-hand turn signal, tail light, and wide vehicle warning light bulbs for broken filaments or internal shorting

2. 2

   Unplug the 7-pin trailer connector (if connected) to check if the fault originates from the trailer wiring

3. 3

   Visually inspect the wiring harness leading to the right-side lights and trailer connector for chafing, pinching, melting, or corrosion

4. 4

   Check the main fuse panel for any related blown fuses

1. 1

   Cycle power

   Turn the tractor's key switch off and then back on to reset the control module and clear potential intermittent faults.

2. 2

   Replace bulbs

   Replace the right-hand turn signal and tail light bulbs with new, correct-specification bulbs, as they can be faulty even if visually intact.

3. 3

   Isolate the circuit

   Activate the right turn signal and disconnect the main connector at the right rear tail light assembly. If the fault code clears, the issue is within the light assembly (e.g., internal short, faulty bulb socket). If it persists, the issue is in the wiring harness.

4. 4

   Test for short to ground

   Disconnect the battery and the relevant connector at the CLC module. Using a multimeter set to Ohms, measure resistance between the right turn signal wire and a known good chassis ground. A low resistance reading indicates a short to ground in the harness.

5. 5

   Repair wiring

   If a short is found, trace the affected wire along the harness, repair the damaged section, and ensure the repair is sealed against moisture.

6. 6

   Replace CLC module

   If no wiring or bulb issues are found, the CLC module may be faulty. Obtain the specific part number using the tractor's serial number. Replacement typically requires programming by a John Deere dealer.
