Common Questions
What does U0137 mean and how does it affect my car?
The U0137 code indicates that your car's engine control module can't communicate with the vehicle dynamics control module, which can affect your car's stability and traction control systems. If not addressed, it may lead to decreased performance and safety risks.
What are the most common causes of U0137 and how much does it cost to fix?
Common causes include damaged wiring (60% likelihood), a faulty vehicle dynamics control module (25%), and poor connections (10%). Repair costs can range from $100 for wiring repairs to $1,200 for ECM replacement.
Can I drive my car with U0137 or should I stop immediately?
It's advised to stop driving your vehicle if you see the U0137 code. Continuing to drive can compromise your vehicle's stability and safety features, potentially leading to accidents.
How can I diagnose U0137 myself using GeekOBD APP?
Using the GeekOBD APP, connect to your vehicle's OBD2 port, scan for codes, and review the freeze frame data to understand the context of the fault. Look for any related codes that may indicate further issues.
What vehicles are most commonly affected by U0137?
This code is frequently seen in models such as the 2015-2018 Ford Focus, 2016-2019 Chevrolet Malibu, and 2017-2019 Honda Civic. Always check for any specific recalls or technical service bulletins (TSBs) related to your vehicle.
How can I prevent U0137 from happening again?
Regular maintenance, including checking and cleaning electrical connections and ensuring software updates for your vehicle's systems, can help prevent future occurrences of the U0137 code.
What is U0137?
The diagnostic trouble code U0137 refers to a communication issue between the engine control module (ECM) and the vehicle dynamics control module (VDM). This code indicates that the ECM is unable to communicate with the VDM, which is responsible for managing stability and traction control systems. Such communication loss can lead to a variety of performance issues, including reduced engine power, erratic braking behavior, and compromised vehicle stability. For instance, if you're driving a 2016 Ford Focus and encounter this code, you may notice that the traction control light stays illuminated, indicating that the system is inactive. The problem may stem from damaged wiring, a faulty VDM, or even issues with the ECM itself. Ignoring this code can lead to further complications, such as poor fuel efficiency and reduced safety features. To ensure your vehicle operates smoothly, addressing the U0137 code promptly is crucial. It’s important to understand that this code may manifest differently across various vehicle makes and models, but the core issue remains the same: a failure in communication between critical modules. Always consult a professional or a reliable diagnostic tool, like the GeekOBD APP, for accurate troubleshooting.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0137 is present:
- The check engine light remains on, indicating a persistent issue that requires attention.
- The traction control light is illuminated, and you might feel the vehicle's stability features are not engaging properly.
- You may experience sluggish acceleration or hesitation during driving, especially when navigating slippery conditions.
- Unusual braking behavior, such as sudden application or release, can occur due to compromised vehicle stability systems.
- Increased fuel consumption may be noticeable, as the vehicle attempts to compensate for the lack of communication between modules.
Possible Causes
Most common causes of U0137 (ordered by frequency):
- The most common cause of U0137 is damaged or corroded wiring between the ECM and VDM, with an estimated likelihood of 60%. This can occur due to wear and tear, exposure to moisture, or physical damage.
- A faulty vehicle dynamics control module is the second most common cause, accounting for around 25% of cases. This may happen due to internal component failure or software issues.
- Poor connections at the ECM or VDM can also trigger U0137, making up about 10% of the problem. Regular inspections can help prevent this issue.
- Less common causes include a malfunctioning engine control module, which can affect overall vehicle performance. This is a serious issue that may require replacement.
- In rare cases, software glitches or updates may cause temporary communication failures. Keeping your vehicle's software up to date can help mitigate this.
