How can I diagnose C179C myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for the C179C code, review freeze frame data for context, and check related codes, which will help pinpoint the exact issue.
What vehicles are most commonly affected by C179C?
The C179C code is often found in models like the 2015-2018 Honda Civic, along with other vehicles featuring similar ABS systems. It's essential to check for any recalls or technical service bulletins related to your specific model.
How can I prevent C179C from happening again?
Regular maintenance of your braking system, including inspections and timely replacements of worn components, can help prevent the recurrence of the C179C code.
What is C179C?
The DTC C179C is a diagnostic trouble code that indicates a malfunction in the vehicle's control module, specifically within the Anti-Lock Braking System (ABS). This code typically appears when the ABS control module detects an issue with the wheel speed sensors or the wiring associated with them. In reality, this can manifest as intermittent brake issues, including loss of ABS functionality, which can lead to decreased vehicle safety, particularly in adverse driving conditions. If left unaddressed, the malfunction could escalate, potentially affecting other systems related to braking and stability control. For owners of 2015-2018 Honda Civics, or similar models from other manufacturers, it's crucial to understand that this code may trigger additional warning lights on the dashboard, such as the ABS light or the brake warning light. The implications of driving with a C179C code can be severe; it’s not just about the warning light but also about the safety of the driver and passengers. Thus, immediate attention should be given to this code to ensure proper vehicle operation and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C179C is present:
- The ABS warning light remains illuminated on the dashboard, indicating a malfunction within the braking system.
- Drivers may experience a noticeable decrease in braking efficiency, especially under heavy braking or slippery conditions, leading to potential safety risks.
- There may be a significant increase in stopping distances, which can be measured against previous performance, resulting in potential accidents.
- Drivers could notice unusual sounds, such as grinding or clicking noises when applying the brakes, indicating underlying mechanical issues.
- In some cases, the brake pedal might feel spongy or unresponsive, leading to a lack of confidence in the braking system.
Possible Causes
Most common causes of C179C (ordered by frequency):
- The most common cause of C179C is a faulty wheel speed sensor, which occurs in about 60% of cases. This can happen due to corrosion or damage to the sensor or wiring.
- Another frequent cause is damaged wiring or connectors within the ABS system. Over time, exposure to environmental factors can lead to wear, affecting sensor performance.
- In some instances, a software glitch in the ABS control module can trigger this code. Regular updates can help prevent this issue.
- A less common but serious cause is a malfunctioning ABS control module itself, which can lead to complete ABS failure if not addressed.
- Rarely, issues with the braking system's hydraulic components can lead to the C179C code, requiring extensive diagnostics and repair.

Diagnostic Steps
Professional C179C Diagnosis Process
Follow these systematic steps to accurately diagnose C179C. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion (5-10 minutes)
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes)
Step 3: Component testing - Use a multimeter or specific diagnostic tools to test the suspected wheel speed sensors and connections (20-30 minutes)
Step 4: System function test - Verify proper operation after repairs and clear codes using the GeekOBD APP (10-15 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm repair success and ensure ABS functionality (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
