The u1008 automobile fault code can be caused by various issues, including a faulty AAF system and poor electrical connections.

  • The automobile fault code u1008 can be caused by a faulty Active Air Flap (AAF) system.
  • It can also be caused by the Engine Control Module (ECM) not communicating with the Active Air Flap (AAF) system.
  • An open or shorted Active Air Flap (AAF) system harness can also cause this fault code.
  • Additionally, a poor electrical connection in the Active Air Flap (AAF) system can be a cause of the u1008 fault code.

Below are the possible fixes for the automobile fault code u1008, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u1008, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code U1008 indicates a communication issue between the engine control module and the transmission control module. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the hourly rate of the auto repair shop.

Most shops charge between $75 and $150 per hour for labor. Therefore, the total cost of fixing the U1008 fault code can range from $75 to $150.

The U1008 fault code indicates a problem with the Active Air Flap (AAF) system in your automobile. This system is responsible for opening and closing a flap between the radiator grille and radiator. During high-speed driving, the flap is closed to reduce air resistance and enhance driving stability.

The Engine Control Module (ECM) opens the flap function if the temperature inside the engine room rises.

If the AAF system is not working to factory specifications, the ECM will set the U1008 code, indicating a lost communication with the radiator shutter. It is important to have this issue addressed promptly to ensure proper functioning of your vehicle.

What is the possible cause of the u1008 fault code in an automobile?

If you’re experiencing the u1008 fault code in your automobile, it could be due to a faulty Active Air Flap (AAF) system, Engine Control Module (ECM) not communicating with the AAF system, an open or shorted AAF system harness, or poor electrical connection. To fix the issue, visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
