ACU 524102.03 – High Voltage in SCV V Control Lever Sensor

ACU 524102.03 (ACU )

Code: 524102.03



This error code, ACU 524102.03, indicates that the voltage in the sensor circuit for the SCV V (Selective Control Valve V) control lever is abnormally high. This could be due to an electrical fault, incorrect wiring, or issues within the sensor itself, leading to potential misreadings and operational inconsistencies.


In response to the high voltage detection, the System Control Computer (SCC) has disabled SCV V to prevent incorrect operation and potential damage to the hydraulic system.


  • Inspect the SCV V control lever sensor and associated circuitry for signs of damage, overheating, or wear that might contribute to high voltage levels.
  • Use a multimeter to check the voltage output at the sensor. Verify that it exceeds normal operating levels and identify potential points of failure.
  • Examine the wiring and connections for any faults that could be causing voltage spikes, such as short circuits or poor insulation.
  • Review the system setup to ensure that all components are correctly installed and configured according to the manufacturer’s specifications.
  • If the issue persists after these checks, recalibrate or replace the sensor to ensure it provides accurate voltage readings. Further electrical diagnostics may be required if component replacement does not rectify the issue.


Proper voltage regulation within the hydraulic control system’s sensors is critical for accurate and safe operation. Regular maintenance and immediate corrective action in response to voltage irregularities are essential to prevent operational disruptions and ensure equipment longevity.
