  • The automobile fault code u11fb can be caused by a faulty left blind spot sensor.
  • It can also be caused by an open or shorted left blind spot sensor harness.
  • Additionally, a poor electrical connection in the left blind spot sensor circuit can also trigger this fault code.

To fix the u11fb automobile 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 u11fb, 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 U11FB 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 U11FB fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The U11FB fault code is related to the Blind Spot Monitor (BSM) system in automobiles. The BSM system has two primary components, the Left Blind Spot Sensor (LBSS) and Right Blind Spot Sensor (RBSS).

The LBSS and RBSS are concealed behind the outboard ends of the rear bumper fascia. The LBSS sends electronic request messages over the CAN Bus to the radio, which generates a chime as an audible alert.

The U11FB code sets when no BUS messages from the LBSS are received for more than 1.05 seconds.

What are the possible causes of the u11fb automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u11fb fault code. This code is caused by a faulty left blind spot sensor, an open or shorted harness, or a poor electrical connection in the left blind spot sensor circuit. To fix this issue, you should visually inspect the 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 wiring harness and connectors related to the Left Blind Spot Sensor?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a faulty Left Blind Spot Sensor, you can visually inspect the related wiring harness and connectors to fix the issue.
