What is B0BD3?
The DTC B0BD3 code indicates a malfunction in the power steering control module. This code is often triggered when the module detects an issue with the power steering system, which may affect the steering feel and responsiveness. In vehicles like the 2015-2020 Chevrolet Malibu, this can lead to a loss of power steering assist, making it challenging to maneuver the vehicle, especially at low speeds. It's essential to address this code promptly, as ignoring it can lead to increased steering effort, especially when parking or making tight turns. The power steering system relies on electronic components to assist in steering, and when the control module malfunctions, it may not relay the necessary information to the electric power steering motor. This can result in the steering wheel feeling heavy or unresponsive. In some cases, drivers may also notice warning lights on the dashboard, indicating a steering system fault. Diagnosing and fixing the underlying cause is crucial for restoring safe and comfortable vehicle operation.
