What is B0CD8?
The DTC code B0CD8 indicates a fault within the Power Steering Control Module (PSCM). This code typically arises in vehicles equipped with electric power steering systems, such as the 2016-2020 Chevrolet Malibu. When the PSCM detects an issue, such as a communication failure or an internal malfunction, it triggers the B0CD8 code. This can lead to reduced steering assist, making it harder to steer the vehicle, particularly at low speeds or during parking maneuvers. Drivers may experience a sudden loss of power steering assistance, a warning light on the dashboard, or unusual steering feedback. If left unaddressed, this issue could result in safety concerns, as steering precision is critical for vehicle control. It's essential for car owners to recognize these symptoms and seek professional diagnosis to prevent potential accidents or further damage to the steering system.

Symptoms
Common symptoms when B0CD8 is present:
- The power steering warning light illuminates on the dashboard, indicating a system fault.
- Steering becomes heavy or difficult, especially during low-speed turns or parking.
- Unusual noises, like whining or grinding, may be audible when turning the steering wheel.
- Steering feedback feels inconsistent, causing a lack of control in handling the vehicle.
- In some cases, the vehicle may experience a complete loss of power steering assist, making it very hard to steer.
Possible Causes
Most common causes of B0CD8 (ordered by frequency):
- The most common cause of B0CD8 is a failure in the Power Steering Control Module, accounting for approximately 60% of cases. This can happen due to electrical issues, software glitches, or physical damage to the module.
- Another frequent cause is faulty wiring or poor connections, which can disrupt communication between the PSCM and the vehicle's control modules.
- A third potential cause is a depleted battery or poor electrical system performance, which can lead to insufficient power supply to the PSCM.
- Less common but serious causes include internal mechanical failure within the steering gear, which can lead to significant steering issues.
- A rare cause could be software corruption in the PSCM, which may require a software update or reprogramming to resolve.
