What is U0544?

DTC U0544 indicates a communication issue between modules in your vehicle's network, specifically relating to the 'Invalid Data Received from Steering Angle Sensor.' This code often appears in modern vehicles equipped with advanced driver-assistance systems (ADAS) like the 2015-2018 Honda Accord, Toyota Camry, and Nissan Altima. When this code triggers, it signals that the Engine Control Unit (ECU) is not receiving the expected data from the steering angle sensor, which could lead to improper vehicle handling or malfunction of systems reliant on accurate steering data. This issue should not be overlooked, as it may impact critical functions such as stability control and power steering. Ignoring the U0544 code can exacerbate underlying issues and potentially lead to unsafe driving conditions. It's essential for car owners to understand that while the check engine light may not illuminate immediately, the effects can manifest in the vehicle's performance. Repairing this issue typically involves checking wiring connections, inspecting the steering angle sensor, and ensuring that all modules are communicating effectively. Prompt attention to the U0544 code will help maintain safe vehicle operation and prevent further complications.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0544 is present:

  • The check engine light remains illuminated, indicating a potential problem with vehicle systems.
  • Drivers may experience erratic steering response, making it difficult to control the vehicle under normal driving conditions.
  • Fuel economy may decrease by 10-15% due to unresponsive electronic systems adjusting to the steering input.
  • Some drivers report experiencing issues with the vehicle's stability control system, particularly during turns.
  • Increased difficulty in executing sharp turns or maneuvers, leading to a feeling of reduced control.

Possible Causes

Most common causes of U0544 (ordered by frequency):

  1. The most common cause of DTC U0544 is a faulty steering angle sensor, which can account for approximately 50% of cases. This sensor can fail due to wear and tear or exposure to moisture.
  2. Another frequent cause is damaged wiring or loose connections, which can disrupt the communication between the sensor and the ECU. About 30% of cases are attributed to wiring issues.
  3. Preventive maintenance, such as regular inspections of wiring and sensors, can help avoid issues with module communication.
  4. Less common but serious causes include software malfunctions within the vehicle’s ECU, which may require a software update or reprogramming.
  5. A rare but possible cause is a malfunctioning ABS module that can also lead to communication errors in multiple sensors.
