This summary uses the existing diagnostic information shown in full below.
This code means that a part of the car that helps it move through the air more easily is getting too much power. It's like when a toy gets too much battery power and doesn't work right.
The Active Aerodynamic Feature Control Module is receiving a higher voltage than expected, which can affect its operation.
The B3A30 code indicates that the Active Aerodynamic Feature Control Module D is experiencing a high voltage condition in its power mode circuit. This module is responsible for adjusting parts of the vehicle to improve aerodynamics, such as spoilers or vents. A high voltage reading can lead to improper functionality or failure of these aerodynamic components.
• Warning light on the dashboard
• Reduced aerodynamic performance
• Unusual noises from aerodynamic components
• Faulty control module
• Wiring issues such as shorts or open circuits
• Faulty voltage regulator
Aerodynamics: The study of how air moves around things.
Voltage: The force that pushes electricity through a wire.
• Check for any blown fuses related to the aerodynamic system.
• Inspect the wiring and connectors for damage or corrosion.
• Test the voltage at the control module to ensure it is within specifications.
• Replace the faulty control module if necessary.
• Repair or replace damaged wiring or connectors.
• Ensure the voltage regulator is functioning properly.
• Multimeter
• OBD-II scanner
• Basic hand tools

Moderate
• Vehicle 1
• Vehicle 2
• Vehicle 3
• Regularly inspect wiring for wear and tear.
• Ensure all electrical components are properly grounded.
• Have the vehicle's electrical system checked during regular maintenance.
Electrical Circuit Issue
• Avoid driving at high speeds until the issue is resolved.
• Consult a professional mechanic if unsure about the repair process.
Check with the vehicle manufacturer for warranty coverage on electrical components.
This code has been associated with vehicles that have advanced aerodynamic features to improve fuel efficiency and performance.
Moderate – It should be addressed soon to maintain optimal vehicle performance.
Ignoring this issue could lead to reduced vehicle performance and potential safety hazards.
• Vehicle must be in a safe location.
• Ensure the vehicle's battery is fully charged.
The Active Aerodynamic Feature Control Module is typically located near the vehicle's front end, often near the radiator or bumper area.
Q: Can I drive my car with this code?
A: It's best to address the issue soon, as it can affect the car's performance.
Q: Will this code cause my car to fail emissions tests?
A: This code is not related to emissions, so it should not affect emissions testing.
