This error code is generated when the control software detects that the signal voltage in the circuit of the declutch switch on the range shift lever is too low when the switch is actuated. Possible reasons include a defective declutch switch, a signal voltage shorted to ground, or an open circuit.

This error code is generated when the control software detects that the signal voltage in the circuit of the declutch switch on the range shift lever is too high when the switch is actuated. Possible reasons include a defective declutch switch, a signal voltage short-circuited to system voltage, or an open ground connection.
- John Deere error OIC codes
This error code is generated when the control software detects that the voltage difference between the declutch switch on the range shift lever and the tractor system voltage is too high when the switch is actuated. This indicates a potential problem with the declutch switch, which may be faulty, dirty, or worn.
