Solution

1. Preparation

Gather the necessary tools and equipment.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery for safety.

2. Retrieve Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Use the scanner to read the stored C-codes.

3. Analyze C-Codes

Cross-reference the retrieved C-codes with the Honda Accord service manual.
Identify any related systems or components affected by the codes.

4. Inspect Components

Examine the components associated with the C-code(s), such as wheel speed sensors, ABS module, or suspension components.
Clean any dirty connectors and check for corrosion.

5. Repair or Replace Faulty Components

If specific components are identified as faulty, replace them with OEM parts.
For example, if a wheel speed sensor is faulty, replace it according to the manufacturer's specifications.

6. Clear Codes and Test

After repairs, use the OBD-II scanner to clear the C-codes.
Take the vehicle for a test drive to ensure the issue is resolved.
