how to troubleshoot brake codes in my Honda CR-V Sixth Generation (2023-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secured with wheel chocks.
• Disconnect the battery before starting any electrical work.

2. Retrieve and Document Error Codes

• Use the OBD-II scanner to connect to the vehicle's diagnostic port.
• Record all error codes and reset them to see if they reappear after a test drive.

3. Inspect Brake Fluid System

• Remove the cap from the master cylinder reservoir.
• Check the brake fluid level against the minimum and maximum marks.
  • If low, top off with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
  • If contaminated, proceed to replace the brake fluid.

4. Brake Line Inspection

• Visually inspect all brake lines and hoses for signs of wear, cracks, or leaks.
• Use a brake line pressure tester to check for leaks under pressure.
• If leaks are found, replace the affected lines or hoses.

5. Brake Pad and Rotor Assessment

• Remove the wheel using a socket set.
• Inspect brake pads for thickness; replace if worn down to less than 3mm.
• Measure rotor thickness with a micrometer; replace if below minimum specifications.
• Clean the brake components with brake cleaner to remove dust and debris.

6. ABS Module and Wiring Check

• Inspect the ABS module for any visible damage or corrosion.
• Check all connectors and wiring associated with the ABS for loose connections or fraying.
• Use a multimeter to test the continuity of ABS sensors.
