It's advisable to stop driving if you see the C0561 code, as it can affect your vehicle's stability and handling, especially in adverse conditions.
How can I diagnose C0561 myself using GeekOBD APP?
By using the GeekOBD APP, you can scan for the C0561 code and view freeze frame data to understand when the issue occurs, facilitating a more accurate diagnosis.
What vehicles are most commonly affected by C0561?
Commonly affected vehicles include the 2014-2018 Chevrolet Silverado and GMC Sierra models, which may experience this code due to their reliance on electronic stability systems.
How can I prevent C0561 from happening again?
Regular maintenance checks on electrical connections and avoiding aftermarket modifications that could interfere with the vehicle's systems are key preventive measures.
What is C0561?
DTC C0561 is a diagnostic trouble code indicating a 'Loss of Communication with the Steering Angle Sensor'. This code typically emerges in vehicles equipped with electronic stability control (ESC) or traction control systems. When your vehicle's onboard computer detects that it can no longer communicate with the steering angle sensor, it triggers this code. This loss of communication can lead to issues with stability control, making it unsafe to drive under certain conditions. Real-world implications include the potential for reduced vehicle handling and increased risk during adverse driving situations, such as slippery roads. If your vehicle is displaying this code, you may notice that the stability control light is illuminated on your dashboard, alerting you to a problem. Ignoring this code can lead to further complications and safety concerns, making it imperative to address it promptly. For those driving popular models like the Chevrolet Silverado or GMC Sierra, understanding this specific code can be crucial for maintaining vehicle performance and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0561 is present:
- The stability control warning light remains on, indicating a potential issue with the vehicle's handling capabilities.
- Unusual steering behavior, such as excessive play or difficulty in steering, which can affect driving comfort and safety.
- The vehicle may exhibit erratic acceleration or deceleration due to the compromised traction control system.
- Increased tire wear may occur if the steering angle sensor is not functioning properly, leading to uneven handling.
- Reduced fuel efficiency may be noted as the vehicle struggles to maintain optimal traction and handling.
Possible Causes
Most common causes of C0561 (ordered by frequency):
- The most common cause is a faulty steering angle sensor, with likelihood around 60%. This sensor is pivotal for maintaining vehicle stability during turns and when navigating slippery surfaces.
- A damaged wiring harness or connector leading to the steering angle sensor could also be the culprit. This is a secondary cause, with about a 25% chance of being the issue, often resulting from wear and tear or improper installation.
- Corrosion or poor electrical connections can cause intermittent communication failures, making it crucial to regularly inspect electrical connections as part of vehicle maintenance.
- Less common, but serious, is a malfunction in the vehicle's Electronic Control Module (ECM), which can lead to multiple fault codes and significant repair costs if not addressed promptly.
- A rare cause could be interference from aftermarket modifications, such as custom audio systems or lighting, which may disrupt the vehicle's onboard communication systems.

Diagnostic Steps
Professional C0561 Diagnosis Process
Follow these systematic steps to accurately diagnose C0561. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Perform an initial visual inspection of the wiring and connectors related to the steering angle sensor
Step 2: Use the GeekOBD APP to conduct an OBD2 scan
Step 3: Test the suspected components using a multimeter to check for proper voltage and connectivity, which might take 20-30 minutes
Step 4: After any repairs, perform a system function test to ensure everything is operating correctly before clearing the codes, which should take around 10-15 minutes
Step 5: Conduct a road test under various conditions to verify that the C0561 code does not reappear, which might take 15-20 minutes
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
