What is C080B?
DTC C080B is a diagnostic trouble code that indicates an issue with the vehicle’s control module, specifically related to the power steering system. This code is commonly associated with vehicles like the 2015-2018 Chevrolet Silverado and GMC Sierra. When C080B is triggered, it typically means there’s a communication problem between the electronic power steering (EPS) control module and the vehicle’s central computer. This could lead to various issues such as loss of power steering assist, resulting in a heavier steering feel. If you experience difficulty steering or notice the steering wheel feels stiffer than usual, this could be a symptom of the C080B code. Ignoring this code can lead to further complications, including potential safety hazards while driving, as power steering is crucial for maneuverability and control. In many cases, this code can stem from faulty wiring, corroded connectors, or issues with the EPS control module itself. It's essential to address this code promptly to maintain your vehicle's performance and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C080B is present:
- Check engine light stays illuminated, indicating the need for immediate diagnostics.
- Steering feels unusually heavy, making it difficult to maneuver, especially at low speeds.
- Unusual noises, such as grinding or whining, when turning the steering wheel.
- Intermittent loss of power steering assist, where the steering may suddenly become stiff during driving.
- Dashboard warning messages related to the steering system may appear intermittently.
Possible Causes
Most common causes of C080B (ordered by frequency):
- Faulty wiring connections account for approximately 40% of C080B occurrences, often due to wear and tear or corrosion.
- A malfunctioning EPS control module is another common cause, which can lead to signal issues and loss of functionality.
- Poor grounding can also contribute to this code, where a weak or corroded ground connection disrupts communication.
- Less common but serious causes include a blown fuse in the power steering circuit that can prevent the system from functioning.
- Rarely, an internal failure within the steering rack assembly can trigger this code, requiring extensive repairs.
