SIC 523885.00 – M13 Stepper Motor EICV 2, Supply Voltage Out of Valid Range High

SIC 523885.00 (SIC )

Code: 523885.00



This error code, SIC 523885.00, is generated when the system voltage (battery voltage) at the stepper motor of EICV 2 (Electro-Hydraulic Integrated Control Valve) exceeds 16 volts.


When this error code is detected, the stepper motor for EICV 2 may be at risk of damage due to overvoltage, potentially leading to erratic operation or failure.


  • Inspect Power Supply:
    • Check the power supply system to ensure it is providing the correct voltage. Replace or repair any components causing the overvoltage.
  • Measure Voltage:
    • Use a multimeter to measure the voltage at the stepper motor to confirm the overvoltage condition.
  • Check Voltage Regulator:
    • Inspect the voltage regulator for proper operation. Replace if malfunctioning.
  • Test Stepper Motor:
    • Ensure the stepper motor has not been damaged due to overvoltage. Replace if necessary.
  • Update Software:
    • Ensure the control unit firmware and software are up to date to rule out any software-related issues that may contribute to overvoltage conditions.


Operating with high supply voltage can lead to significant damage to the stepper motor and associated components. Regular inspection and maintenance of the power supply system are essential to prevent such issues. If the problem persists, consult technical support for further diagnosis and repair.
