This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's system that controls parts that help the car move through air better, like a spoiler. It's like a toy with a part that won't move because the battery is not connected right.
The B3A2E code indicates an issue with the electrical circuit that powers the control module for active aerodynamic features, such as movable spoilers or air vents.
The Active Aerodynamic Feature Control Module C is responsible for managing components that adjust the vehicle's aerodynamics. A 'Power Mode Circuit/Open' fault suggests a disruption in the power supply, possibly due to a broken wire, a disconnected connector, or a faulty module.
• Warning light on the dashboard
• Reduced fuel efficiency
• Aerodynamic features not functioning
• Faulty wiring or connectors
• Defective Active Aerodynamic Feature Control Module
• Blown fuse or relay failure
Aerodynamics: The study of how air moves around things.
Control Module: A computer in the car that controls certain features.
• Check for any blown fuses related to the module.
• Inspect wiring and connectors for damage or disconnection.
• Test the control module for proper operation.
• Replace any blown fuses and test the system.
• Repair or replace damaged wiring or connectors.
• Replace the Active Aerodynamic Feature Control Module if faulty.
• Multimeter
• OBD-II scanner
• Basic hand tools (screwdrivers, pliers)
$150 - $500
Moderate
• Vehicle 1
• Vehicle 2
• Vehicle 3
• Regularly inspect and maintain wiring and connectors.
• Ensure fuses and relays are in good condition.
• Avoid exposure to moisture and extreme temperatures.
Electrical Circuit Issue
• Have a professional inspect the vehicle if the warning light appears.
• Avoid using the vehicle's aerodynamic features until repaired.
Check with your vehicle manufacturer for warranty coverage on electronic modules.
This code has been reported in vehicles with advanced aerodynamic systems, typically in models from the mid-2010s onwards.
Moderate – It's important to address this issue to maintain vehicle efficiency and performance.
Operating a vehicle with malfunctioning aerodynamic features may affect handling and fuel efficiency.
• Vehicle ignition in 'ON' position
• Aerodynamic features activated
The control module is typically located in the trunk or rear of the vehicle, near the aerodynamic components it controls.
Q: Can I drive my car with this code?
A: Yes, but it's best to get it fixed soon to ensure your car runs efficiently.
Q: Will this issue affect my car's performance?
A: It might reduce fuel efficiency and affect handling if the aerodynamic features are not working.
