What vehicles are most commonly affected by U0363?
Vehicles such as the 2015-2018 Honda Accord, as well as other models from manufacturers like Toyota and Ford with similar EPS systems, frequently experience this code.
How can I prevent U0363 from happening again?
Regular maintenance checks on your vehicle's steering system, keeping connections clean and secure, and ensuring software updates are performed can help prevent future occurrences of the U0363 code.
What is U0363?
DTC code U0363 indicates a communication problem within the vehicle's control modules, specifically related to the Steering Angle Sensor (SAS) or the Electronic Power Steering (EPS) system. This code is most frequently seen in vehicles like the 2015-2018 Honda Accord, but it can also affect other makes and models equipped with similar electronic systems. When this code triggers, it suggests that the communication between the EPS control module and other vehicle modules is compromised. This disruption can lead to a variety of issues, including loss of power steering assistance or erratic steering behavior, which can be dangerous. Drivers may experience a stiff steering wheel or warning lights on the dashboard. Ignoring this code could result in further damage to the steering system or even affect vehicle safety. Therefore, it is crucial to address U0363 promptly. The underlying problems could range from software glitches to faulty sensors or wiring issues. A proper diagnostic procedure using OBD2 scanners, such as the GeekOBD APP, is essential to identify the root cause and implement the correct repairs to restore normal operation.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0363 is present:
- Check engine light remains illuminated, indicating a potential issue with the steering system.
- Steering wheel feels unusually heavy or stiff, especially during low-speed maneuvers or parking.
- Erratic steering response, where the vehicle may veer off course or feel unresponsive.
- Increased difficulty when turning corners, leading to a tiring driving experience.
- Dashboard warning lights such as EPS or steering assist may illuminate, alerting drivers to a malfunction.
Possible Causes
Most common causes of U0363 (ordered by frequency):
- Faulty Steering Angle Sensor (SAS) - 40%: A common issue where the SAS fails to transmit accurate data to the EPS module, leading to communication errors.
- Wiring Issues - 30%: Damaged or corroded wires in the steering system can disrupt communication, often due to wear and tear over time.
- Software Glitches - 20%: Outdated or corrupt software in the EPS module can prevent proper functioning, requiring a software update or reprogramming.
- Weak Battery or Voltage Issues - 5%: Low battery voltage can cause the EPS system to malfunction, leading to communication errors.
- Rare Sensor Failures - 5%: In rare cases, the EPS control module itself may fail, which is less common but can be costly to repair.
