This diagnostic trouble code is generated if the control software registers that the current at the output to the left side-facing worklight on the rear of the roof is too high. This indicates a short circuit to ground.
- John Deere error RLC codes
This diagnostic trouble code is generated if the control software registers that the current at the output to the left middle worklight on the front of the roof or left Xenon (HID) worklight on the front of the roof is too high. This indicates a short circuit to ground.
- John Deere error RLC codes
This diagnostic trouble code is generated if the control software registers that the current at the output to the left middle worklight on the front of the roof or left Xenon (HID) worklight on the front of the roof is too low. This indicates that the circuit is open.
- John Deere error RLC codes
This diagnostic trouble code is generated if a voltage higher than the expected value is registered at the output to the left middle worklight on the front of the roof or left Xenon (HID) worklight on the front of the roof. This indicates that the circuit is open or shorted to 12 volts.
- John Deere error RLC codes
This diagnostic trouble code is generated if the control software registers that the current at the output to the left outer worklight on the front of the roof, left turn-signal light on the front of the roof (SAE), or left extra-wide vehicle turn-signal light (SAE) is too high. This indicates a short circuit to ground.

This diagnostic trouble code is generated if the control software registers that the current at the output to the left outer worklight on the front of the roof, left turn-signal light on the front of the roof (SAE), or left extra-wide vehicle turn-signal light (SAE) is too low. This indicates that the circuit is open.
