AIC 003509.04 (AIC 3509.04) – 5V Sensor Supply Voltage Deficiency

AIC 003509.04 (AIC 3509.04)

Code: 003509.04

Shortcode: 3509.04

Description:

This error code, AIC 3509.04, flags that the voltage for the 5V sensor supply 1 in the Armrest Interface Control Unit has fallen below 4.8 volts, which could indicate a short to ground or an internal fault within the control unit itself.

Reaction:

The reduced voltage has caused a degradation in the functionality of systems reliant on this power supply, limiting their operational efficiency to prevent further complications.

Recommendations:

  • Conduct a thorough inspection of the 5V sensor supply circuit for potential shorts to ground. Pay close attention to the wiring and connections for any signs of wear, damage, or improper insulation.
  • Utilize a multimeter to verify the voltage levels and help localize the source of the voltage drop within the circuit.
  • Examine the control unit for signs of internal faults, such as damaged components or board issues, which might be contributing to the low voltage output.
  • Replace or repair any faulty components identified during the diagnostic process. Ensure all repairs adhere to manufacturer specifications for safe and effective function.
  • After addressing the issue, recalibrate the sensor supply settings if necessary and perform comprehensive testing to confirm that the voltage is now stable and within the required range, and that full functionality has been restored.

Note:

Regular checks and prompt maintenance of the electrical supply systems within control units are essential to ensure stable operation and prevent issues that could lead to operational failures or system damage.
