Common Questions
What does B0AE5 mean and how does it affect my car?
The B0AE5 code indicates a problem with your vehicle's Electric Power Steering system. When this code appears, it can lead to a heavy steering feel, especially at low speeds, making it harder to maneuver the vehicle. Long-term neglect of this issue may cause further complications and affect your vehicle's safety and drivability.
What are the most common causes of B0AE5 and how much does it cost to fix?
Common causes of the B0AE5 code include a faulty power steering control module, damaged wiring, or low fluid levels. Repair costs can range from $150 for simple wiring repairs to $600 for module replacement, depending on the specific issue.
Can I drive my car with B0AE5 or should I stop immediately?
While you may be able to drive short distances with the B0AE5 code, it is not advisable to do so. The loss of power steering assist can make steering difficult, increasing the risk of an accident. It is best to address this issue as soon as possible.
How can I diagnose B0AE5 myself using GeekOBD APP?
To diagnose B0AE5 with the GeekOBD APP, connect the app to your vehicle's OBD2 port. Retrieve the diagnostic codes and review the freeze frame data to understand the context. Check for other related codes that might help narrow down the issue.
What vehicles are most commonly affected by B0AE5?
The B0AE5 code is frequently encountered in the 2017-2020 Chevrolet Bolt. Other General Motors vehicles equipped with EPS may also exhibit this code, especially those manufactured during the same period.
How can I prevent B0AE5 from happening again?
Regular vehicle maintenance, including checking fluid levels and inspecting wiring connections, can help prevent the B0AE5 code from recurring. Additionally, keeping the software of your vehicle's control modules updated can help avoid glitches.
What is B0AE5?
The B0AE5 diagnostic trouble code (DTC) refers to an issue with the Electric Power Steering (EPS) system. This code is commonly found in vehicles like the 2017-2020 Chevrolet Bolt and other models that use EPS. When the B0AE5 code is triggered, it indicates that the power steering control module has detected a malfunction in the EPS system, which can lead to a loss of power steering assist. This can make steering more difficult, especially at low speeds, and may lead to increased driver fatigue. The underlying issue might stem from a variety of factors, including faulty wiring, a malfunctioning power steering control module, or an electrical fault within the steering system. Ignoring this code can lead to further damage and a more expensive repair bill. Additionally, it can compromise vehicle safety, as a driver may struggle to steer effectively, especially in emergency situations. Therefore, addressing the B0AE5 code promptly is crucial for both safety and vehicle performance.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0AE5 is present:
- The check engine light illuminates on the dashboard, indicating a potential steering issue.
- The steering wheel feels unusually heavy, especially when turning at low speeds, making maneuvering difficult.
- Increased effort required to steer the vehicle, which can lead to driver fatigue during longer trips.
- Unusual noises such as whining or grinding may be heard when turning the steering wheel.
- The power steering assist may intermittently fail, leading to sudden changes in steering response.
Possible Causes
Most common causes of B0AE5 (ordered by frequency):
- The most common cause of the B0AE5 code is a faulty power steering control module, occurring in about 60% of cases. This module may fail due to wear or electrical issues.
- A second cause could be damaged wiring or connectors within the EPS system, which can lead to intermittent connectivity and faults.
- Another common cause is low power steering fluid levels, which can happen due to leaks. Regularly checking fluid levels can help prevent this issue.
- Less commonly, the steering column itself may have mechanical issues, which can lead to failure in the EPS system.
- A rare but significant cause could be software glitches in the vehicle's computer system that require a software update to resolve.
