- The diagnostic trouble code (DTC) U0415 is defined as “Invalid Data Received From Anti-Lock Brake System (ABS) Control.”
- This code is triggered when one or more modules on the CAN bus determine that the ABS module is sending out invalid data.
- The U0415 code can be caused by damaged wiring or poor connections, a bad ABS control module, or faulty ABS sensors.
- A triggered P0415 code can cause problems with the ABS. The check engine light, ABS warning light, and other warning lights can also turn on.
The anti-lock brake system (ABS) keeps the wheels from locking up and stops the tires from slipping whenever the vehicle brakes during a panic stop. It helps you maintain control, thereby contributing to your safety.
The PCM will log a U0415 code if it receives implausible data from the ABS control module.
What Does the U0415 Code Mean?
The diagnostic trouble code (DTC) U0415 indicates “Invalid Data Received From Anti-Lock Brake System (ABS) Control.”
Responsible for running the anti-lock brake system, the ABS control module monitors how fast each wheel spins through its ABS wheel sensors. It sends the readings to the PCM and also shares the information with other modules through the controller area network (CAN) bus.
If one or more modules on the bus determine the ABS module is sending out invalid data, the generic code U0415 will be set.
Note: Depending on who manufactured the vehicle, the definition of code U0415 can differ. To find the exact code definition, refer to the appropriate repair manual or repair database.
What are the Common Causes of the U0415 Code?
- Circuit problems, such as a damaged wire or poor connection
- Defective ABS control module
- A problem with one or more of the sensors that input their data to the ABS module
What are the Common Symptoms of the U0415 Code?
- Check engine light turns on
- Problems with the ABS
- Illuminated ABS warning light
- Other warning lights might illuminate
How to Diagnose the U0415 Code
The U0415 code is a generic code that various makes and models can log. However, the problem that triggered the code can vary, and a diagnostic and repair approach that worked on some vehicles may not prove effective on others.
If you’re not confident about running diagnostic tests on your vehicle, it’s a good idea to bring it to a certified mechanic. Otherwise, you can go ahead and diagnose the issue yourself. To help you get started, here is a video that can give you an idea of what the process might involve:
How to Fix the U0415 Code
Attempting to fix a U0415 code can prove a challenging task if you don’t have the right tools and know-how to test the ABS control. You will have to track down the cause of the problem–otherwise, the issues will persist.
For DIYers with advanced technical knowledge and hands-on experience who prefer to test and fix their vehicle’s ABS control on their own, it will be helpful to rely on the appropriate repair manual or refer to an online repair database.
