What is C1108?
DTC C1108 indicates a malfunction related to the wheel speed sensor, which is crucial for your vehicle's anti-lock braking system (ABS). When this code appears, it typically signifies that the ABS control module has detected an inconsistency in the wheel speed sensor readings. This could be due to a faulty sensor, damaged wiring, or issues within the ABS control module. For instance, in vehicles such as the 2016 Honda Accord and the 2017 Toyota Camry, a malfunctioning wheel speed sensor can lead to problems with braking performance. If the sensor fails, it may cause the ABS system to not engage properly during hard braking, which can increase stopping distances and compromise safety. Additionally, drivers might experience the ABS warning light illuminating on the dashboard. Ignoring this code can lead to more significant issues with the braking system, potentially resulting in costly repairs down the line. Therefore, understanding and addressing DTC C1108 promptly is essential for maintaining your vehicle's safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1108 is present:
- Check engine light or ABS warning light stays on constantly, indicating a malfunction in the ABS system.
- Unusual braking behavior, such as the brakes locking up or feeling 'spongy' during sudden stops.
- Increased stopping distance when applying brakes, which can be measured by noticeable delays in response.
- Decreased traction control functionality, leading to slipping during wet or slippery conditions.
- Potential vibrations or noises from the ABS system during braking, suggesting underlying issues.
Possible Causes
Most common causes of C1108 (ordered by frequency):
- Faulty wheel speed sensor is the most common cause (about 70% likelihood), often due to wear and tear or exposure to road debris.
- Damaged wiring or connectors related to the wheel speed sensor can also trigger this code, often due to corrosion or chafing.
- A malfunctioning ABS control module may cause erroneous readings, necessitating a more in-depth diagnostic approach.
- Less common but serious causes include brake system fluid leaks affecting sensor operation.
- Rarely, issues within the vehicle's computer system can lead to false DTC C1108 readings, requiring advanced diagnostics.

Diagnostic Steps
Professional C1108 Diagnosis Process
Follow these systematic steps to accurately diagnose C1108. 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 - Use the app to retrieve all codes and freeze frame data to understand the fault context (10-15 minutes)
Step 3: Component testing - Utilize a multimeter or specific diagnostic tools to test the wheel speed sensor and related wiring (20-30 minutes)
Step 4: System function test - After repairs, verify the proper operation of the ABS system 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 the ABS functions correctly (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
