What is U0B58?

DTC U0B58 is a diagnostic trouble code that indicates an issue related to the vehicle communication network, specifically pointing to a problem within the communication between various control modules. In simpler terms, it’s a signal that something is amiss in how your car’s different electronic systems talk to each other. For owners of vehicles such as the 2017-2022 Toyota Camry, this code may manifest when the engine control module (ECM) fails to receive or send information correctly to other electronic control units (ECUs) including the transmission control module, ABS module, or even the infotainment system. This can lead to a variety of symptoms such as erratic engine performance, issues with shifting, and even problems with safety systems like traction control. Ignoring this code can lead to more significant issues down the line, as a malfunctioning communication network may result in poor vehicle performance or even cause the vehicle to become undriveable. Therefore, it's crucial to address the U0B58 code promptly to ensure your vehicle remains in optimal running condition.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0B58 is present:

  • The check engine light remains illuminated, signaling a malfunction that needs attention.
  • Drivers may experience engine hesitation during acceleration, causing unsafe driving conditions.
  • Fuel economy may decrease significantly, with reports of a 10-15% drop in efficiency.
  • Erratic behavior of the infotainment system, such as freezing or crashing.
  • Issues with automatic transmission shifting, leading to unexpected gear changes.

Possible Causes

Most common causes of U0B58 (ordered by frequency):

  1. The most common cause is a faulty wiring harness, with about 40% likelihood, which can create poor connections between modules.
  2. A malfunctioning ECM is another significant contributor, as it may fail to send or receive data correctly.
  3. Corrosion at connection points can result in intermittent issues; regular inspections can help prevent this.
  4. A less common but serious cause is a failed ECU, which may require replacement.
  5. Rarely, software bugs in the control modules can lead to this code; updates from manufacturers can resolve these issues.
