Diagnostic trouble code BCU 524224.02 is an informational alert generated to notify the operator that the rear PTO (Power Take-Off) was activated after the HMS Plus (Headland Management System Plus) was engaged, despite the rear PTO not being programmed to operate within the HMS Plus sequences. This alert serves to prevent potential operational conflicts or…

Diagnostic trouble code BCU 524055.31 is generated when the Basic Control Unit (BCU) is not calibrated, is incorrectly calibrated, or if the calibration process has not been completed. This code may also be triggered mistakenly during procedures such as hitch calibration. This code is classified under the alarm level “Information,” indicating that it serves primarily…

Diagnostic trouble code BCU 524055.11 is generated when an internal fault occurs within the control unit, specifically linked to an intervention by the internal module (EEPROM). The EEPROM (Electrically Erasable Programmable Read-Only Memory) is critical for storing firmware and configuration settings in the control unit. Faults in this component can lead to issues with storing…

Diagnostic trouble code BCU 523924.19 is triggered when there is an issue with the CAN (Controller Area Network) bus communication, specifically the output for switching the left xenon (HID) worklight on the rear of the roof (E31L) being energized by more than one control unit. This condition suggests a misconfiguration within the vehicle’s control system,…

Diagnostic trouble code BCU 523924.12 is activated when the power module PC0 detects a current exceeding 1 amp in lead 1036, despite the left xenon (HID) worklight on the rear of the roof (E31L) being switched off. This condition typically indicates a short in the circuit or an internal fault within the power module, which…

Diagnostic trouble code BCU 523924.09 is triggered when there is a communication issue between the power module PC0 and the Basic Control Unit (BCU) regarding the E31L left Xenon (HID) worklight on the rear of the roof. The problem involves intermittent or nonexistent reception of CAN (Controller Area Network) messages from the BCU to power…

Diagnostic trouble code BCU 523924.05 is triggered when the power module PC0 measures a current of less than 500 mA in lead 1036, even though the left xenon (HID) worklight on the rear of the roof (E31L) is switched on. This condition typically indicates an open circuit, suggesting a break or disconnection in the electrical…

Diagnostic trouble code BCU 523924.04 is triggered when the power module PC0 detects a current exceeding 15 amps in lead 1036 while the left xenon (HID) worklight on the rear of the roof (E31L) is switched on. This unusually high current condition typically indicates a short to ground within the circuit, which can lead to…

Diagnostic trouble code BCU 523924.01 is triggered when the power module PC0 measures a supply voltage of less than 3 volts at lead 0782 while the E31L left Xenon (HID) worklight on the rear of the roof is switched on. This low voltage reading indicates a power supply fault, potentially due to inadequate wiring, poor…
