AIC 000158.03 (AIC 158.03) – High Switched Supply Voltage

AIC 000158.03 (AIC 158.03)

Code: 000158.03

Shortcode: 158.03

Description:

This error code, AIC 158.03, is triggered when the switched supply voltage to the Armrest Interface Control Unit (AIC) exceeds 18 volts. Such high voltage indicates potential overcharging or an electrical anomaly in the system’s power supply.

Reaction:

As a protective measure to prevent damage to electronic components and ensure system safety, the control unit has disabled the affected function.

Recommendations:

  • Inspect the power supply system and check for any abnormalities or failures that could be causing the high voltage issue.
  • Measure the voltage levels using a multimeter to verify that they exceed the normal operating range and pinpoint the source of the high voltage.
  • Review all electrical connections and wiring associated with the AIC unit for signs of damage, wear, or improper connections that might contribute to voltage spikes.
  • Adjust or replace any faulty electrical components, such as regulators or capacitors, that could be responsible for the overvoltage.
  • After implementing corrective actions, retest the system to ensure that the voltage has normalized and the functionality is restored.

Note:

Monitoring and maintaining proper voltage levels within the AIC system are essential for optimal performance and longevity of the equipment. Regular electrical system checks can help prevent such issues and ensure the reliability of the machinery.
