[SOLVED] Fixing U11Bc: Brake Switch Message Lost

The automobile fault code U11BC indicates a problem with the Brake Pedal Position (BPP) Sensor, which can trigger the Engine Light to turn on. The possible causes of this issue include a faulty BPP sensor, an open or shorted BPP sensor harness, poor electrical connection in the BPP sensor circuit, a faulty Anti-Lock Brake System (ABS) module, or a faulty Powertrain Control Module (PCM).

The importance of fixing this issue lies in ensuring the proper functioning of the brake system. The repair difficulty is moderate, and the fix involves visually inspecting the wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins. The repair time is estimated to be around 1.0 hour.

To interpret the fault code, one needs to check the vehicle’s service manual or consult a professional mechanic.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of u11bc fault code.

Here are the symptoms to look out for:

  • The automobile fault code U11BC has the following symptoms: – Engine Light ON (or Service Engine Soon Warning Light) – The engine may not start – The engine may stall or hesitate – The vehicle may experience reduced power – The transmission may shift harshly or erratically – The fuel efficiency may decrease – The vehicle may emit excessive smoke or fumes – The exhaust system may make unusual noises – The vehicle may experience difficulty in passing emissions tests.

The automobile fault code u11bc can be caused by various factors, including a faulty BPP sensor and ABS or PCM issues.

  • The automobile fault code u11bc can be caused by a faulty Brake Pedal Position (BPP) Sensor.
  • It can also be caused by an open or shorted Brake Pedal Position Sensor harness.
  • A poor electrical connection in the Brake Pedal Position Sensor circuit can also trigger this fault code.
  • Another possible cause is a faulty Anti-Lock Brake System (ABS) Module.
  • Lastly, a faulty Powertrain Control Module (PCM) can also be the reason behind the u11bc fault code.

To fix the u11bc automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code u11bc, 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 U11BC 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 U11BC 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 U11BC fault code is related to the brake switch signal received by the Powertrain Control Module (PCM) from the Anti-Lock Brake System (ABS) Module.

The PCM sets the Diagnostic Trouble Code (DTC) when it doesn’t receive the brake switch signal from the ABS Module over the CAN C bus. This fault code is a one-trip fault and is identified as U11BC – Lost Brake Switch Message.

What are the possible causes of the u11bc automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u11bc automobile fault code. This code is usually caused by a faulty brake pedal position (BPP) sensor, an open or shorted BPP sensor harness, a poor electrical connection in the BPP sensor circuit, a faulty anti-lock brake system (ABS) module, or a faulty powertrain control module (PCM). To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.

How can the faulty Brake Pedal Position Sensor be fixed in case of the u11bc fault code?

If you’re experiencing the u11bc fault code, indicated by the engine light or service engine soon warning light, it may be due to a faulty Brake Pedal Position (BPP) Sensor. To fix this issue, start by checking the possible causes listed above, including inspecting the wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector pins.

What steps should be taken to visually inspect the wiring harness and connectors related to the u11bc fault code?

To visually inspect the wiring harness and connectors related to the u11bc fault code, first check the possible causes listed above. Then, inspect the related wiring harness and connectors for any damage or broken, bent, pushed out, or corroded pins. This will help identify any issues with the Brake Pedal Position Sensor harness, Anti-Lock Brake System Module, or Powertrain Control Module.
