[SOLVED] U1345 Code: How To Fix Engine Control Module Lin Bus

The automobile fault code U1345 indicates a problem with the control module, which is setting the Diagnostic Trouble Code (DTC). The most common symptom is the Engine Light ON or Service Engine Soon Warning Light.

The cause of this fault code could be a faulty control module, an open or shorted control module harness, or a poor electrical connection in the control module circuit. The repair importance is high as it can affect the performance of the vehicle. The repair difficulty is moderate, and the repair time is estimated at 1.0 hour.

To fix the issue, one 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. It is essential to interpret the fault code correctly to avoid further damage to the vehicle.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the u1345 fault code. Here are the symptoms to look out for:

  • The U1345 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, and the vehicle may not start.
  • Additionally, the vehicle may experience a loss of power, reduced fuel efficiency, and poor acceleration.
  • It is important to address these symptoms promptly to avoid further damage to the vehicle and ensure safe driving conditions.

The automobile fault code U1345 can be caused by a faulty control module, open or shorted harness, or poor electrical connection.

  • The automobile fault code U1345 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 U1345 fault code in automobiles.

Below are some possible fixes for the automobile fault code u1345, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u1345, 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 U1345 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 U1345 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The U1345 code is related to the Engine Control Module LIN Bus.

The Local Interconnect Network (LIN) Bus is a single wire with a transmission rate of 10.417 Kbits. Serial data is transmitted over a LIN circuit between a master control module and other LIN devices within a particular subsystem. If serial data communication is lost between any of the LIN devices on the LIN bus network, the master control module will set a no communication code against the non-communicating LIN device.

The U1345 code sets when a supervised periodic message that includes the transmitter device availability has not been received.

What are the possible causes of the u1345 automobile fault code?

If your engine light is on and you’re seeing the u1345 fault code, it could be due to 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 I visually inspect the related wiring harness and connectors to fix the u1345 fault code?

If you’re experiencing the U1345 fault code, which is indicated by the engine light being on, you can visually inspect the related wiring harness and connectors to fix the issue. This fault code is caused by 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 fix the issue, check the possible causes listed above and visually inspect the wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector pins.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the u1345 fault code?

If you encounter damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the u1345 fault code, follow these steps. First, visually inspect the related wiring harness and connectors. Then, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Finally, fix any issues found during the inspection to ensure the proper functioning of the control module and prevent the engine light from turning on.
