This summary uses the existing diagnostic information shown in full below.
The car has a special part called an air dam that helps with airflow. This code means there's a problem with the wires or connection that control this part.
The Active Air Dam is a component that adjusts to improve aerodynamics and fuel efficiency. An open circuit means there's a break or disconnection in the electrical path that controls it.
The C0601 code indicates that the vehicle's control module has detected an open circuit in the control wiring of the active air dam system. This can result from a broken wire, a disconnected connector, or a malfunctioning control module.
• Check Engine Light is on
• Reduced fuel efficiency
• Unusual airflow noise
• Broken or damaged wiring
• Disconnected or loose connectors
• Faulty control module

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regularly inspect wiring for damage.
• Ensure connectors are secure and free from corrosion.
• Schedule periodic maintenance checks.
Control Circuit Issue
• Avoid driving at high speeds until repaired to prevent further damage.
• Consult a professional mechanic for diagnosis and repair.
Check with your vehicle manufacturer for warranty coverage on electronic components.
The C0601 code has been reported in vehicles with advanced aerodynamic features, typically affecting models with active air management systems.
Moderate – While the vehicle can still be driven, it may experience reduced efficiency and performance.
Driving with a malfunctioning air dam can affect vehicle performance and fuel efficiency. Ensure repairs are made promptly.
• Vehicle at operating temperature
• Vehicle stationary with engine running
The active air dam is typically located at the front lower section of the vehicle.
Q: Can I drive with the C0601 code?
A: Yes, but it's best to fix it soon to avoid reduced fuel efficiency and potential further damage.
Q: How do I reset the C0601 code?
A: After repairs, use an OBD-II scanner to clear the code from the vehicle's computer.
