What is U0362?
The DTC code U0362 indicates a communication error between the vehicle's onboard diagnostic system and the steering control module. This code is prevalent in various vehicles, particularly in models like the 2015-2020 Chevy Silverado. When this code appears, it signifies that the steering control module is unable to transmit or receive data correctly, which can lead to issues with the power steering system. In real-world terms, this may manifest as difficulty in steering, increased steering effort, or even the complete loss of power steering assistance. The steering control module plays a crucial role in ensuring that the electric power steering functions smoothly, and any disruption in communication can compromise vehicle handling and safety. Ignoring this issue may not only lead to more severe steering problems but can also result in increased repair costs down the line. It's essential to address this code promptly to maintain optimal vehicle performance and safety on the road.
System: U - Network (Communication, CAN Bus)
