This fault code is generated when the hydraulic oil filter restriction sensor detects high voltage for an extended period, indicating a restricted filter. A clogged filter can lead to increased pressure in the hydraulic system, which may degrade system performance and increase the risk of component failure.

This fault code indicates that the hydraulic oil temperature sensor has detected oil temperatures higher than normal operating levels, but not yet reaching a critically hot threshold. This situation can still adversely affect system efficiency and increase wear on hydraulic components.
- John Deere error CCU codes
This fault code indicates that the Chassis Control Unit (CCU) has detected that the hydraulic oil temperature sensor is shorted to ground, resulting in a low voltage condition. Additionally, it may also occur under specific conditions related to engine speed, hydraulic oil temperature, and engine coolant temperature.
- John Deere error CCU codes
This fault code is triggered when the Chassis Control Unit (CCU) detects that the hydraulic oil temperature sensor circuit is open, leading to a high voltage condition. Additionally, it may also occur under specific conditions related to engine speed, hydraulic oil temperature, and engine coolant temperature.
- John Deere error CCU codes
This fault code indicates that the Chassis Control Unit (CCU) has detected that the hydraulic oil temperature is at a critically high level, signaling that the fluid is too hot to continue safe operation. High hydraulic oil temperatures can lead to reduced system efficiency, increased wear on components, and potential damage to the hydraulic system.

This code is set when the Chassis Control Unit (CCU) detects that the air brake pressure switch is open, indicating that the air pressure in the brake system is insufficient. This situation can impair the ability to safely control the vehicle’s braking capabilities, particularly at startup when the air pressure may not yet have built…
- John Deere error CCU codes
This fault code alerts to a situation where the voltage in the air brake pressure sensor circuit is below normal, or the sensor is shorted to a low voltage source. Low voltage at the sensor can lead to incorrect brake pressure readings, compromising the accuracy and reliability of the brake system, which is crucial for…
- John Deere error CCU codes
This fault code is set off when the voltage in the air brake pressure sensor circuit is higher than normal, or if the sensor is shorted to a high voltage source. High voltage can result in inaccurate pressure readings, which are critical for the safe operation of the vehicle’s air brake system.
- John Deere error CCU codes
This fault code indicates that the voltage supplied to the sensors is below the normal operating range, specifically falling below 4.8 volts. Low voltage can impair the sensors’ ability to accurately detect and transmit data, potentially affecting the overall functionality of various control systems within the vehicle.
