ACU 524102.04 – Low Voltage in SCV V Control Lever Sensor

ACU 524102.04 (ACU )

Code: 524102.04



This error code, ACU 524102.04, signifies that the voltage within the SCV V (Selective Control Valve V) control lever sensor circuit is registering below expected levels. Low voltage readings can indicate issues such as insufficient power supply, degraded wiring, or a faulty sensor, which can compromise the accuracy of control lever inputs.


To prevent potential malfunctions or incorrect operations of the hydraulic system due to unreliable sensor input, the SCC (System Control Computer) has disabled the SCV V function.


  • Conduct a thorough inspection of the SCV V control lever sensor and associated electrical circuitry for any signs of wear, corrosion, or damage that could be causing the low voltage condition.
  • Measure the voltage output at the sensor using a multimeter to confirm it is below the required threshold. This will help identify if the problem is localized to the sensor or if broader electrical issues are present.
  • Check all electrical connections and wiring for loose connections, breaks, or other faults that could affect the voltage levels.
  • Ensure that all components are receiving adequate power and that there are no issues with the power supply that could be impacting the sensor’s performance.
  • Recalibrate the sensor or replace it if it fails to meet voltage requirements during testing. Ensure that any new components are compatible with the existing system and properly integrated.


Regular maintenance and monitoring of the electrical components within the hydraulic control system are essential for ensuring reliable operation. Addressing issues like low voltage promptly helps maintain system integrity and prevent downtime.
