[SOLVED] Fix U1175 Code: Ignition Status Lost – Here’s How

If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light, it could be due to the automobile fault code: u1175.

This code is typically caused by a faulty Electronic Ignition System (EIS), an open or shorted EIS harness, a poor electrical connection in the EIS circuit, or a faulty Powertrain Control Module (PCM). The importance of repairing this issue lies in the fact that it can affect the performance of your vehicle. The repair difficulty is moderate, with a repair time of 1.0.

To fix the 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.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of u1175 fault code. Here are the symptoms to look out for:

  • The U1175 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 speedometer may not work properly.
  • These symptoms can indicate a problem with the ABS module or a communication issue between the ABS module and the engine control module.
  • It is important to have the vehicle diagnosed and repaired by a qualified mechanic to prevent further damage and ensure safe driving.

The automobile fault code u1175 can be caused by a faulty EIS, open or shorted harness, poor electrical connection, or a faulty PCM.

  • The automobile fault code U1175 can be caused by a faulty Electronic Ignition System (EIS).
  • It can also be caused by an open or shorted Electronic Ignition System harness.
  • Another cause can be a poor electrical connection in the Electronic Ignition System circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also trigger the U1175 fault code.

To fix the u1175 fault code, check the possible causes and inspect the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code u1175, 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 U1175 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 U1175 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 U1175 fault code is related to the Electronic Pedestrian Protection Module (EPPM) in a vehicle. This code is set when the EPPM does not receive a vehicle ignition switch status signal from the Electronic Ignition System (EIS) over the Controller Area Network (CAN) C bus for 25 seconds.

The Airbag Warning Lamp (AWL) will be on while the faulted condition is active. The code will change to a stored code if the EPPM receives a vehicle speed signal for over one second.

In summary, the U1175 code indicates a lost ignition status message between the EPPM and EIS, which can cause the Airbag Warning Lamp to turn on.

What are the possible causes of the u1175 automobile fault code?

If you’re experiencing the u1175 fault code, your engine light may be on. This could be due to a faulty Electronic Ignition System (EIS), an open or shorted EIS harness, a poor electrical connection in the EIS circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors related to the Electronic Ignition System?

If your engine light is on due to a faulty Electronic Ignition System (EIS), you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. Also, check for an open or shorted Electronic Ignition System harness and circuit poor electrical connection. Finally, check for a faulty Powertrain Control Module (PCM).

Is it necessary to check for damaged components and connector pins when fixing the u1175 fault code?

Yes, it is necessary to check for damaged components and connector pins when fixing the u1175 fault code. The Engine Light ON (or Service Engine Soon Warning Light) may indicate a faulty Electronic Ignition System (EIS), an open or shorted EIS harness, a poor electrical connection in the EIS circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, visually inspect the related wiring harness and connectors, and check for damaged components and broken, bent, pushed out, or corroded connector pins.
