What vehicles are most commonly affected by C08AF?
Models such as the 2016-2021 Nissan Rogue, Nissan Sentra, and Nissan Altima frequently report the C08AF code. Stay updated on any recalls or TSBs related to your vehicle.
How can I prevent C08AF from happening again?
Regular maintenance, including checking the steering system for wear and ensuring connections are secure, can help prevent C08AF from recurring. Consider scheduled inspections for older vehicles.
What is C08AF?
The C08AF diagnostic trouble code (DTC) is associated with the vehicle's advanced driver assistance systems, specifically related to the steering control system. When this code is triggered, it indicates that there is a malfunction within the electronic steering system, which can significantly affect the vehicle's maneuverability and safety features. This code is commonly found in vehicles such as the 2016-2021 Nissan Rogue, Nissan Sentra, and Nissan Altima. Drivers may experience symptoms such as a warning light on the dashboard, difficulty steering, or the steering feeling unresponsive. If the code persists, it could lead to more serious problems, including complete loss of steering assist, making immediate diagnosis and repair crucial. Ignoring the C08AF code can also lead to further damage to the steering components, ultimately increasing repair costs. Therefore, it's essential for car owners to understand what this code means and to address it promptly to maintain their vehicle's safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C08AF is present:
- The check engine light or steering warning light illuminates on the dashboard, indicating a need for immediate attention.
- Drivers may experience increased difficulty when steering, particularly at low speeds, which can feel like the steering wheel is heavier than usual.
- There may be a noticeable loss of steering assist, making it challenging to turn the vehicle smoothly, especially during parking maneuvers.
- Some vehicles might emit unusual noises when turning the steering wheel, which can indicate issues within the steering system.
- A decrease in fuel efficiency may be observed due to increased strain on the engine from the failing steering assist system.
Possible Causes
Most common causes of C08AF (ordered by frequency):
- The most common cause of the C08AF code is a malfunctioning electric power steering control unit, which accounts for about 60% of cases. This unit is responsible for providing the necessary assist to the steering mechanism.
- Another frequent cause is damaged wiring or connectors within the steering system, often resulting from wear and tear or exposure to road conditions.
- Improper calibration after replacing components related to the steering system can also trigger the C08AF code, indicating the need for a reset.
- A less common but serious issue could be an internal failure in the steering column assembly, which may require complete replacement and can be quite costly.
- In rare instances, software glitches in the vehicle's electronic control unit (ECU) can cause false readings and trigger the C08AF code.

Diagnostic Steps
Professional C08AF Diagnosis Process
Follow these systematic steps to accurately diagnose C08AF. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Perform an initial visual inspection of the steering system
Step 1: Perform an initial visual inspection of the steering system. Check for damaged wiring, loose connectors, or signs of wear on the steering components (5-10 minutes).
Step 2: Step 2: Connect the vehicle to an OBD2 scanner, such as the GeekOBD APP, to retrieve the C08AF code and any related trouble codes
Step 2: Connect the vehicle to an OBD2 scanner, such as the GeekOBD APP, to retrieve the C08AF code and any related trouble codes. Review freeze frame data for context (10-15 minutes).
Step 3: Step 3: Conduct component testing using a multimeter to assess the voltage and ground of the electric power steering control unit (20-30 minutes)
Step 3: Conduct component testing using a multimeter to assess the voltage and ground of the electric power steering control unit (20-30 minutes).
Step 4: Step 4: If repairs have been made, conduct a system function test to ensure that the steering is operating correctly and clear any stored codes (10-15 minutes)
Step 4: If repairs have been made, conduct a system function test to ensure that the steering is operating correctly and clear any stored codes (10-15 minutes).
Step 5: Step 5: Finally, take the vehicle for a road test under various conditions to confirm that the issue has been resolved and that the steering operates smoothly (15-20 minutes)
