[SOLVED] U1347 Code: How To Fix Lin Bus 3 Error

The automobile fault code U1347 indicates a problem with the control module, which can trigger the engine light or service engine soon warning light. The cause of this issue can be a faulty control module setting the diagnostic trouble code, an open or shorted control module harness, or a poor electrical connection in the control module circuit.

The importance of repairing this fault code lies in the fact that it can affect the performance of the vehicle. The repair difficulty is moderate, and it takes around 1.0 hour to fix. To interpret the fault code, one needs to check the possible causes listed above and visually inspect the related wiring harness and connectors for any damage or corrosion.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the u1347 fault code. Here are the symptoms to look out for:

  • The U1347 fault code in an automobile can cause the following symptoms: Engine Light ON, Service Engine Soon Warning Light, ABS Light ON, Traction Control Light ON, Brake Light ON, Speedometer not working, Cruise Control not working, and Transmission shifting problems.

The automobile fault code U1347 can be caused by a faulty control module, open or shorted harness, or poor electrical connection.

  • The automobile fault code U1347 can be caused by a faulty control module that sets the diagnostic trouble code (DTC).
  • It can also be caused by an open or shorted control module harness.
  • Additionally, a poor electrical connection in the control module circuit can also trigger this fault code.
  • These are the three main causes of the U1347 fault code in automobiles.

Below are some possible fixes for the automobile fault code u1347, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u1347, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for 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 U1347 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the U1347 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 U1347 fault code is related to the Engine Control Module (ECM) LIN Bus.

The Local Interconnect Network (LIN) Bus is a single wire transmission system with a rate of 10.417 Kbits. The LIN circuit is used to transmit serial data between the master control module and other LIN devices within a subsystem. If the master control module loses communication with any of the LIN devices on the network, it will set a no communication code against the non-communicating device.

The U1347 code sets when the ECM does not receive a supervised periodic message that includes the transmitter device availability.

What are the possible causes of the u1347 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u1347 fault code. This code is usually caused by a faulty control module setting the diagnostic trouble code (DTC), an open or shorted control module harness, or a poor electrical connection in the control module circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the u1347 fault code?

If you’re experiencing the U1347 fault code, which is indicated by the engine light or service engine soon warning light turning on, there are a few things you can do to fix it. The cause of this issue could be a faulty control module setting the diagnostic trouble code, an open or shorted control module harness, or a poor electrical connection in the control module circuit. To address this problem, you should visually inspect the related wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

What are the consequences of ignoring the u1347 fault code and not fixing it in a timely manner?

Ignoring the u1347 fault code can lead to serious consequences such as reduced fuel efficiency, engine misfires, and even engine failure. The fault code indicates a problem with the control module, which can cause the engine light to turn on. It is important to fix the issue in a timely manner by visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken or corroded pins.
