Common Questions

What does U0244 mean and how does it affect my car?

The U0244 code signifies a communication error between various control modules, especially between the ABS module and the main control unit. This can lead to compromised safety features, such as traction control and braking efficiency. If ignored, it can result in reduced vehicle performance and safety hazards, especially under adverse driving conditions.

What are the most common causes of U0244 and how much does it cost to fix?

The most common cause of U0244 is a faulty ABS module, which can cost between $400 and $800 to replace. Wiring issues and poor connections are also frequent culprits, typically costing around $100 to $300 to repair. Software updates can be a less costly solution, ranging from $50 to $150.

Can I drive my car with U0244 or should I stop immediately?

It is advisable to stop driving the vehicle and seek immediate diagnostics if you see the U0244 code. Continuing to drive can lead to safety issues, particularly with braking and traction control, increasing the risk of accidents.

How can I diagnose U0244 myself using GeekOBD APP?

Use the GeekOBD APP to perform an OBD2 scan, which will help you retrieve the U0244 code and any associated trouble codes. Analyze the freeze frame data to understand the context of the fault and check the module connections and wiring visually for any obvious issues.

What vehicles are most commonly affected by U0244?

The U0244 code is commonly reported in vehicles like the 2015-2018 Ford F-150 and the 2016-2018 Chevrolet Silverado. Other models may also experience this code, so always consult your vehicle's diagnostic manual for specifics.

How can I prevent U0244 from happening again?

Regular vehicle maintenance, including checking wiring and connections, can help prevent U0244 from recurring. Ensure any aftermarket devices are properly installed and avoid exposing critical wiring to moisture or harsh conditions.

What is U0244?

The diagnostic trouble code (DTC) U0244 indicates a communication error between various control modules in your vehicle, particularly related to the anti-lock brake system (ABS) or electronic stability control (ESC). This code often arises when the ABS module fails to communicate effectively with the vehicle's main control unit, leading to potential safety issues. Car owners may experience a range of symptoms, including the illumination of the check engine light, reduced braking efficiency, and possible activation of traction control issues. This code can affect various makes and models, but is especially prevalent in vehicles like the Ford F-150 and Chevrolet Silverado during the years 2015 to 2018. The underlying causes can include wiring faults, poor connections, or the failure of the ABS module itself. If not addressed, a U0244 code can lead to decreased vehicle performance and compromised safety features, making it essential for drivers to seek diagnostic and repair services promptly.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0244 is present:

  • Check engine light stays on constantly, indicating a potential issue with vehicle systems and communication.
  • Traction control light may activate unexpectedly during normal driving conditions, suggesting a malfunction.
  • Reduced braking efficiency, which may manifest as longer stopping distances or the ABS not engaging as intended.
  • Unusual noises from the ABS module or related components, which can indicate internal failures.
  • Inconsistent vehicle handling, particularly in slippery conditions, owing to malfunctioning stability control.

Possible Causes

Most common causes of U0244 (ordered by frequency):

  1. Faulty ABS module (60% likelihood) - This is the most common cause, where the ABS module fails to send or receive signals properly.
  2. Wiring issues (25% likelihood) - Damaged or corroded wiring connecting the ABS module to the main control unit can inhibit communication.
  3. Poor connections (10% likelihood) - Loose or corroded connectors can disrupt the flow of information between modules.
  4. Less common but serious cause: Software issues (5% likelihood) - Outdated or corrupt software in the vehicle's control modules can lead to communication problems.
  5. Rare but possible cause: External electrical interference (1% likelihood) - Interference from aftermarket accessories or devices can occasionally cause communication errors.
