The automobile fault code u1176 can be caused by a faulty RFA, open or shorted harness, or poor electrical connection.

  • The automobile fault code U1176 can be caused by a faulty Remote Function Actuator (RFA).
  • It can also be caused by an open or shorted Remote Function Actuator harness.
  • Additionally, a poor electrical connection in the Remote Function Actuator circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code u1176, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u1176, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look 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 U1176 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 fixing the U1176 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The U1176 code is related to the loss of remote function actuator communication in a vehicle. Modules in the class 2 serial data circuit monitor for serial data communications during normal vehicle operation.

When a module doesn’t receive a message for a critical operating parameter, it uses a default value for that parameter. If a module doesn’t receive a Node Alive message from a learned identification number for 5 seconds, a Diagnostic Trouble Code (DTC) U1176 is set.

What are the possible causes of the u1176 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u1176 fault code. This code is often caused by a faulty Remote Function Actuator (RFA), an open or shorted RFA harness, or poor electrical connection in the RFA circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
