If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the u11d2 fault code.

Here are the symptoms to look out for:

  • The U11D2 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include issues with the transmission, such as difficulty shifting gears or the transmission slipping.
  • The vehicle may also experience reduced power or acceleration, and the engine may run rough or stall.
  • Additionally, the vehicle may experience issues with the fuel system, such as difficulty starting or poor fuel economy.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code u11d2 can be caused by a faulty PCM, ABS module, or TCM.

  • The automobile fault code U11D2 can be caused by a faulty Powertrain Control Module (PCM).
  • It can also be caused by a faulty Anti-lock Braking System (ABS) Module.
  • Additionally, a faulty Transmission Control Module (TCM) can also trigger this fault code.
  • These are the three main causes of the U11D2 fault code in automobiles.

Below are the possible fixes for the automobile fault code u11d2, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u11d2, 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 U11D2 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 U11D2 will depend on the hourly rate charged by the repair shop.

It is important to consider the repair time and hourly rate when estimating the cost of fixing this fault code.

The U11D2 fault code checks the validity of the brake switch message sent by the ABS module via CAN network. It performs a CRC and message counter check to verify the brake switch message is continuously updated and has a valid value.

If the toggle bit value does not change or the signal parity is not verified for a calibrated amount of time, the U11D2 DTC is set, indicating a lost brake signal.
