This fault code indicates that the Chassis Control Unit (CCU) detects the rear PTO external switch function is being requested while the rear PTO switch is off. This serves as a safety alert to indicate that the CCU is ready to turn on the rear PTO with the external switch. The code primarily acts as…

This fault code is triggered when the Chassis Control Unit (CCU) detects a malfunction in the rear PTO solenoid driver or circuit. The issue can be due to an open circuit, short circuit, or an over-temperature condition. The fault is identified while the rear PTO is disengaged. The CCU expects a specific current but receives…

This fault code is triggered when the Chassis Control Unit (CCU) detects that the rear PTO is engaged while the operator is not present in the seat or if the operator leaves the seat while the PTO is engaged. This condition can be operator-induced, either by failing to engage the PTO properly or by not…

This fault code occurs when there is a conflict between the MFWD switch command and the command from the Intelligent Total Equipment Control (iTEC™) system. Specifically, it is detected when iTEC™ is turned off while commanding MFWD, resulting in a mismatch between iTEC™ and the MFWD switch command. This situation is typically operator-induced.

This fault code indicates that the Chassis Control Unit (CCU) has detected a malfunction in the Mechanical Front-Wheel Drive (MFWD) solenoid driver or circuit. This can occur due to an open circuit, a short circuit, or an over-temperature condition. The fault is detected while the MFWD is disengaged, suggesting an issue with the solenoid’s ability…

This fault code indicates that the Chassis Control Unit (CCU) detects a mismatch between the commanded state (ON or OFF) of the rear PTO switch and the actual input signal received by the CCU. This discrepancy can be caused by several conditions, including incorrect configuration, improper operation, or communication issues within the control units.

This fault code indicates a voltage mismatch between the direct input signal for the rear PTO ON switch and the CAN message from the Armrest Control Unit (ACU). This discrepancy suggests a communication error or fault within the PTO switch or ACU.

This fault code is activated when the Chassis Control Unit (CCU) detects that the differential lock switch has been closed for more than 15 seconds after power-up. This condition may be caused by an obstruction, such as a foot or floor mat, inadvertently pressing the switch.

This fault code is triggered when the Chassis Control Unit (CCU) detects that the brake assist and auto switch inputs for the Mechanical Front-Wheel Drive (MFWD) system are both ON simultaneously for longer than 3 seconds. This condition indicates a malfunction or miscommunication within the MFWD switch circuit.

This fault code indicates that the switched supply voltage (wake-up voltage) from the Cab Load Center (CLC) control unit to the Chassis Control Unit (CCU) is below the normal operating range. The wake-up voltage, which should be between 12.5 and 14.5 volts, is essential for powering various sensors and control units. Low voltage can affect…

This fault code is triggered when the hydraulic oil filter restriction sensor detects high pressure while the engine speed is above 1500 RPM for more than 15 seconds. This condition suggests that the filter is bypassed due to excessive pressure, which can occur if the filter is heavily restricted or if there is a fault…
