This error code, AIC 639.14, indicates that the error limit for the Armrest Interface Control Unit (AIC) on the vehicle’s CAN Bus system has been surpassed. This fault could stem from a short circuit, an open circuit, or excessive traffic, all of which disrupt normal operations and communication across the CAN Bus.

The error code AIC 639.12 is triggered when the error threshold on the Armrest Interface Control Unit (AIC) for the vehicle’s CAN Bus has been exceeded. This situation could be caused by a short circuit, an open circuit, or excessive traffic on the CAN Bus, which disrupts normal communication and data flow.

This error code, AIC 629.12, arises when the software within the Armrest Interface Control Unit (AIC) fails to execute within the allotted time frame. This delay can indicate processing issues, such as system overloads or software inefficiencies, which prevent the control unit from performing its functions promptly.

This status code, AIC 628.12, indicates that the Armrest Interface Control Unit (AIC) is currently in the process of updating or loading new software. It is important to note that this is a normal programming status, not an error code, and occurs solely during the software update process.

This error code, AIC 628.02, is triggered when an issue is detected during the reading process of the internal module (EEPROM) within the Armrest Interface Control Unit (AIC). Such a fault can indicate data corruption, EEPROM failure, or a communication error within the internal memory system of the control software.

This error code, AIC 168.04, signals that the unswitched supply voltage to the Armrest Interface Control Unit (AIC) has dropped below 9.0 volts. Such low voltage might be caused by a depleted battery, inadequate charging, or poor electrical connections.

READ MORE

This error code, AIC 168.03, indicates that the unswitched supply voltage to the Armrest Interface Control Unit (AIC) has exceeded 18 volts. This high voltage condition can occur due to an overcharging issue or a malfunction in the voltage regulation system.

READ MORE

This error code, AIC 158.04, is issued when the switched supply voltage to the Armrest Interface Control Unit (AIC) drops below 9.0 volts. This low voltage condition suggests issues such as undercharging, a failing power source, or electrical connections that are not providing sufficient power.

READ MORE

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.
