[SOLVED] Fixing U11E9 Code: Active Grill Shutter Communication Lost

If you see the engine light on or the service engine soon warning light, it could be due to a faulty Active Grill Shutter (AGS) Assembly. The automobile fault code U11E9 indicates that there is an issue with the AGS assembly harness, circuit, or a poor electrical connection. It could also be caused by a faulty Powertrain Control Module (PCM).

The importance of fixing this issue lies in the fact that it affects the engine’s performance and fuel efficiency.

The repair difficulty is moderate, and it takes about 1.0 hour to fix.

To interpret the fault code, check the possible causes listed above and visually inspect the related wiring harness and connectors.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of u11e9 fault code. Here are the symptoms to look out for:

  • The automobile fault code U11E9 is associated with several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, poor acceleration, rough idling, stalling, and difficulty starting the vehicle.
  • Additionally, the transmission may shift roughly or fail to shift at all, and there may be a decrease in fuel efficiency.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe operation on the road.

The automobile fault code u11e9 can be caused by a faulty AGS assembly, open or shorted AGS harness, poor electrical connection, or a faulty PCM.

  • The automobile fault code u11e9 can be caused by a faulty Active Grill Shutter (AGS) Assembly.
  • It can also be caused by an open or shorted Active Grill Shutter Assembly harness.
  • Another cause can be a poor electrical connection in the Active Grill Shutter Assembly circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also trigger this fault code.

Below are some possible fixes for the automobile fault code u11e9, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u11e9, 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 automobile fault code U11E9 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of diagnosis and fixing the U11E9 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The u11e9 fault code is related to the Active Grill Shutter (AGS) Assembly. It occurs when the Powertrain Control Module (PCM) does not receive a valid Local Interconnect Network (LIN) BUS message from the AGS Assembly for 2.6 seconds.

This results in a lost communication with the AGS Assembly. The AGS Assembly is responsible for controlling the airflow through the grille of the vehicle. If this fault code is not addressed, it can lead to decreased fuel efficiency and engine performance.

It is important to have a qualified mechanic diagnose and repair the issue to ensure proper functioning of the AGS Assembly and overall vehicle performance.

What are the possible causes of the u11e9 fault code?

If you’re experiencing the u11e9 fault code, your engine light may be on. This could be due to a faulty Active Grill Shutter (AGS) Assembly, an open or shorted AGS Assembly harness, a poor electrical connection in the AGS Assembly circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the u11e9 fault code?

If you’re experiencing the u11e9 fault code, which is indicated by the engine light being on or the service engine soon warning light, there are a few things you can do to fix it. The possible causes include a faulty Active Grill Shutter (AGS) Assembly, an open or shorted AGS Assembly harness, a poor electrical connection in the AGS Assembly circuit, or a faulty Powertrain Control Module (PCM). To address these issues, you should visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

Is a faulty Powertrain Control Module a common cause of the u11e9 fault code?

While a faulty Powertrain Control Module (PCM) is listed as one of the possible causes of the u11e9 fault code, it is not a common cause. The most common cause of this fault code is a faulty Active Grill Shutter (AGS) Assembly or an issue with the AGS Assembly harness. To fix the issue, it is recommended to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
