ACU 001080.04 (ACU 1080.04 ) – Low Voltage in Sensor Supply 2

ACU 001080.04 (ACU 1080.04)

Code: 001080.04

Shortcode: 1080.04


The error code ACU 1080.04 indicates that the Sensor Supply 2 circuit within the armrest control unit is experiencing low voltage. This condition suggests potential issues such as insufficient power supply, faulty wiring, or a malfunctioning sensor that could affect the overall sensor performance and reliability.


In response to the low voltage detection, the control unit has degraded function, which may limit the performance or responsiveness of the connected systems to prevent further complications.


  • Inspect the wiring and connections associated with Sensor Supply 2 for any signs of damage, wear, or loose connections that could be causing the low voltage.
  • Test the voltage output with a multimeter to verify it is below the required level and identify potential points of failure in the circuit.
  • Check the power source and ensure it is delivering adequate voltage and current as required by the system.
  • Consider replacing any faulty components, such as sensors or wires, that are identified during the troubleshooting process.
  • If the issue persists, consult with a qualified technician who can provide a more in-depth diagnostic and possible system recalibration.


Continuous operation under low voltage conditions can lead to decreased system efficiency and increased wear on electronic components. It is crucial to address these issues promptly to maintain optimal functionality and prevent system failures.
