CCU 003509.04 – Sensor Supply Voltage Out of Range Low

CCU 003509.04 (CCU 3509.04)

Code: 003509.04

Shortcode: 3509.04

Description:

This fault code indicates that the voltage supplied to sensors is below the normal operational range, specifically dropping below 4.8 volts. This could be due to a failing battery, poor wiring, or issues within the vehicle’s charging system, leading to inadequate sensor performance and potential system malfunctions.

Reaction:

The control unit degrades certain functionalities to prevent incorrect sensor operations and potential system errors due to low voltage.

Recommendations:

  • Check Battery and Charging System: Evaluate the condition of the battery and the effectiveness of the charging system to ensure they are providing adequate power.
  • Inspect Wiring and Connections: Ensure that all electrical connections are secure and that wires are not damaged or corroded, which could contribute to voltage drops.
  • Verify Voltage Levels: Use diagnostic tools to check the actual voltage being supplied to the sensors and address any discrepancies.
  • Replace Faulty Components: If any components of the electrical system are found to be faulty, replace them to restore proper voltage levels.
  • Calibration and System Testing: Once repairs are made, recalibrate any affected sensors and perform comprehensive system tests to ensure all operations are back to normal.

Note:

Maintaining stable and adequate voltage levels is essential for sensor accuracy and overall system reliability. Regular checks can help identify and rectify voltage issues promptly.
