[SOLVED] Fix Keyless Ignition Node Communication With U103C Code Solution

If you see the engine light on or the service engine soon warning light, it could be due to the automobile fault code: u103c. This code indicates a problem with the Keyless Ignition Node (KIN) or Radio Frequency Hub (RF Hub). The cause could be a faulty KIN, open or shorted KIN harness, poor electrical connection in the KIN circuit, or a faulty RF Hub.

The importance of fixing this issue lies in the fact that it can affect the starting and stopping of the engine.

The repair difficulty is moderate, and it takes around 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, it could be due to the u103c fault code.

Here are the symptoms to look out for:

  • The fault code U103C is associated with several symptoms that include the engine light turning on or the service engine soon warning light.
  • Other symptoms include issues with the transmission, problems with the ABS system, and difficulty starting the vehicle.
  • Additionally, the vehicle may experience reduced power or acceleration, and the speedometer may not function correctly.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code u103c can be caused by a faulty KIN, open or shorted KIN harness, poor electrical connection in KIN circuit, or a faulty RF Hub.

  • The automobile fault code U103C can be caused by a faulty Keyless Ignition Node (KIN).
  • It can also be caused by an open or shorted Keyless Ignition Node harness.
  • Another possible cause is a poor electrical connection in the Keyless Ignition Node circuit.
  • Lastly, a faulty Radio Frequency Hub (RF Hub) can also trigger this fault code.

To fix the automobile fault code u103c, check the possible causes and inspect the related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code u103c, 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 U103C has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the fixing cost of U103C will range between $75 and $150, depending on the repair time required.

These factors should be considered when estimating the cost of fixing the U103C fault code.

The U103C fault code is related to the Security Keyless Line Communication circuit in the automobile. This code is triggered when the Radio Frequency Hub (RF Hub) detects an open or a short to ground in the circuit.

The fault code indicates a problem with the Keyless Ignition Node Communication in the vehicle.

It is important to address this issue promptly to ensure proper functioning of the keyless ignition system.

What are the possible causes of the u103c automobile fault code?

If you’re experiencing the u103c automobile fault code, you may notice that your engine light is on or that the service engine soon warning light is illuminated. This issue can be caused by a few different factors, including a faulty Keyless Ignition Node (KIN), an open or shorted Keyless Ignition Node harness, a poor electrical connection in the Keyless Ignition Node circuit, or a faulty Radio Frequency Hub (RF Hub). To fix the problem, it’s important to check the possible causes listed above and visually inspect the related wiring harness and connectors for any damage or corrosion.

How can I visually inspect the related wiring harness and connectors to fix the u103c fault code?

If you’re experiencing the u103c fault code, which is indicated by the engine light being on, you may be able to fix it by visually inspecting the related wiring harness and connectors. This fault code can be caused by a faulty Keyless Ignition Node (KIN), an open or shorted KIN harness, a poor electrical connection in the KIN circuit, or a faulty Radio Frequency Hub (RF Hub). To fix the issue, check the possible causes listed above and inspect the wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector pins.

Is a faulty Radio Frequency Hub (RF Hub) a common cause of the u103c fault code?

A faulty Radio Frequency Hub (RF Hub) is listed as one of the possible causes of the u103c fault code, which triggers the Engine Light ON or Service Engine Soon Warning Light. 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.
