ACU 524102.02 – SCV V Lever Switch and Sensor Voltage Conflict

ACU 524102.02 (ACU )

Code: 524102.02



This error code, ACU 524102.02, is raised when there is a conflict between the SCV V (Selective Control Valve V) control lever switch position and the corresponding sensor voltage readings. This inconsistency can suggest a fault in either the switch mechanism or the sensor’s ability to accurately reflect lever position through voltage levels.


Due to the detected conflict, the SCV V is automatically disabled by the System Control Computer (SCC) to prevent potential misoperation or damage to the hydraulic system.


  • Conduct a thorough examination of the SCV V control lever switch and associated sensor to check for mechanical wear, electrical faults, or misalignments that could be causing the voltage discrepancies.
  • Measure and record the voltage outputs at various positions of the SCV V control lever to determine whether the sensor is accurately tracking the switch movements.
  • Inspect all related wiring and electrical connections for damage, corrosion, or looseness that could interfere with accurate voltage transmission.
  • Calibrate the SCV V lever and sensor to align the mechanical positions with the electrical output using the manufacturer’s specified procedures.
  • If recalibration does not resolve the issue, consider replacing the faulty switch or sensor. Ensure that all new components are compatible with the existing hydraulic control system.


Maintaining synchronization between mechanical controls and their corresponding electrical signals is essential for the accurate operation of hydraulic systems. Regular diagnostics and maintenance can help prevent such conflicts and ensure reliable system performance.
