Common Questions
What does C1107 mean and how does it affect my car?
DTC C1107 indicates an issue with the Anti-lock Brake System, which can compromise your vehicle's braking performance. If not addressed, it may lead to longer stopping distances and reduced vehicle control, especially in emergency situations.
What are the most common causes of C1107 and how much does it cost to fix?
Common causes include a faulty ABS control module (around $400-$800 to fix) and malfunctioning wheel speed sensors (approximately $150-$300). Regular inspections can help identify issues early, reducing repair costs.
Can I drive my car with C1107 or should I stop immediately?
It's advisable to address C1107 immediately. Driving with this code could lead to decreased braking performance, which poses a safety risk. If the ABS light is on, it's best to have the vehicle checked as soon as possible.
How can I diagnose C1107 myself using GeekOBD APP?
You can use the GeekOBD APP to scan the OBD2 system for diagnostic trouble codes. The app will help you retrieve the C1107 code, view freeze frame data, and monitor real-time sensor data, aiding in pinpointing the issue.
What vehicles are most commonly affected by C1107?
DTC C1107 is frequently seen in vehicles like the 2007-2011 Toyota Camry and 2010-2015 Honda Accord. It's important to stay updated on any recalls or technical service bulletins (TSBs) related to the ABS system in these models.
How can I prevent C1107 from happening again?
Regular maintenance, including inspecting the ABS system components and keeping wiring connections clean and secure, can help prevent C1107 from recurring. Additionally, timely brake system inspections can catch issues early.
What is C1107?
DTC C1107 is a diagnostic trouble code that indicates a problem with the vehicle's Anti-lock Brake System (ABS). Specifically, this code refers to a malfunction in the ABS control module or an issue with the wheel speed sensors that monitor the rotation of the wheels. When this code is triggered, it usually means that the ABS system cannot properly function, which can lead to compromised braking performance in certain scenarios, such as during panic stops or on slippery surfaces. Car owners may experience a variety of symptoms, including the illumination of the ABS warning light on the dashboard, which serves as a clear sign that something is amiss with the braking system. In vehicles like the 2007-2011 Toyota Camry and 2010-2015 Honda Accord, this code is not uncommon and can be indicative of wiring issues or sensor failures. Ignoring this code can lead to increased stopping distances and reduced vehicle control, critical factors for safe driving. Therefore, it's essential to address the problem promptly to ensure the safety and reliability of your vehicle.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1107 is present:
- ABS warning light remains illuminated on the dashboard, indicating a problem with the ABS system.
- Brake pedal feels soft or spongy, which may lead to a decrease in braking effectiveness.
- Unusual noises from the ABS unit when applying brakes, such as grinding or clicking sounds.
- Loss of traction control, especially during heavy braking or on wet/slippery surfaces, leading to potential skidding.
- Increased stopping distance noted by the driver, which can be a serious safety concern.
Possible Causes
Most common causes of C1107 (ordered by frequency):
- The most common cause of C1107 is a faulty ABS control module, which is responsible for regulating the ABS system and can fail due to electrical issues or wear, with a likelihood of about 35%.
- Another frequent cause is malfunctioning wheel speed sensors, which monitor the speed of each wheel and send this data to the ABS control module; if they fail, they can trigger the C1107 code.
- Wiring issues, such as frayed or corroded connectors leading to intermittent signals, can also cause the C1107 code to appear, making up roughly 20% of cases.
- Less common but serious causes include hydraulic control unit failures that can lead to complete ABS system failure, thus requiring immediate repair.
- A rare cause could be software issues within the ABS control module that may necessitate a software update or reprogramming to resolve the error.

Diagnostic Steps
Professional C1107 Diagnosis Process
Follow these systematic steps to accurately diagnose C1107. 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 ABS control module and wheel speed sensors (20-30 minutes)
Step 4: System function test - Verify proper operation after repairs and clear codes (10-15 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm repair success (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
