Common causes of U0364 include a faulty body control module, damaged wiring, and poor connections. Repair costs can vary significantly. For a BCM replacement, expect to pay between $300 and $800, while wiring repairs might cost between $150 and $400. Software issues could be resolved for as little as $100.

Can I drive my car with U0364 or should I stop immediately?

It's advisable to limit driving your vehicle if you see the U0364 code. While it may still be drivable, the electrical issues could pose risks, especially if safety features are compromised. It's best to seek diagnostic assistance as soon as possible to avoid potential hazards.

How can I diagnose U0364 myself using GeekOBD APP?

To diagnose U0364 using the GeekOBD APP, connect your device to the OBD2 port and run a full scan. Note the retrieved codes and any freeze frame data that could help pinpoint when the issue occurred. The app can also assist in monitoring live data to gauge how the BCM interacts with other modules.

What vehicles are most commonly affected by U0364?

U0364 is frequently reported in vehicles like the 2015-2018 Ford F-150, 2016-2018 Chevrolet Silverado, and various Chrysler models. Owners of these vehicles should be aware of this code and watch for related symptoms, especially as they age.

How can I prevent U0364 from happening again?

Preventative measures include regular electrical system checks, ensuring all connections are secure and free from corrosion, and keeping an eye on battery health. Additionally, consider periodic software updates from your dealership, as they can mitigate potential BCM issues.

What is U0364?

DTC U0364 is a diagnostic trouble code that indicates a communication error between the vehicle's body control module (BCM) and other control modules. This code is prevalent in various models, particularly the 2015 to 2018 Ford F-150, as well as some Chrysler and GM vehicles. When this code is triggered, it means that the BCM is unable to receive or send signals properly, which can lead to multiple electrical issues, such as malfunctioning lights, window controls, and other electronic components. This communication breakdown could stem from faulty wiring, a defective BCM, or even issues with the vehicle's power supply. If left unaddressed, U0364 can escalate into more significant electrical malfunctions, potentially affecting the vehicle's overall performance and safety features. Therefore, understanding this code is crucial for any car owner experiencing electrical anomalies, as timely diagnosis and repair can prevent further complications and ensure your vehicle operates smoothly.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0364 is present:

  • Check engine light remains illuminated, indicating a significant communication issue that needs immediate attention.
  • Electrical components like windows, locks, or lights may intermittently work or fail to respond, affecting overall vehicle functionality.
  • Fuel economy may decrease due to improper operation of engine management systems linked to the BCM.
  • Erratic behavior of dashboard indicators, where warning lights may flicker or display false readings.
  • Inconsistent operation of safety features like stability control or anti-lock brakes could be compromised.

Possible Causes

Most common causes of U0364 (ordered by frequency):

  1. The most common cause is a faulty body control module, accounting for about 50% of cases, often due to internal failures or software glitches.
  2. Wiring issues such as frayed or shorted wires can lead to communication failures; this occurs in roughly 30% of cases.
  3. Corroded or loose connections in the harness can interrupt signals; ensure regular inspections to prevent this.
  4. Less common but serious causes include software problems that may require reprogramming of the BCM.
  5. Rarely, a failing battery or alternator can cause voltage drops that affect module communication.
