how to troubleshoot Honda CR-V Sixth Generation (2023-present) brake warning light

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface, engage the parking brake, and turn off the ignition.
• Wear safety gloves and goggles for protection.

2. Check and Refill Brake Fluid

• Tools Required: Clean rag, funnel.
• Inspect the brake fluid reservoir; if the fluid is low, clean the area around the cap to prevent contamination, and remove the cap.
• Using a funnel, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) to the recommended level.
• Replace the cap securely and clean any spilled fluid.

3. Inspect and Replace Brake Pads

• Tools Required: Jack and jack stands, lug wrench, socket set, brake pad spreader.
• Loosen the lug nuts on the front or rear wheels where pads need inspection.
• Raise the vehicle with a jack and secure on jack stands.
• Remove the wheel and inspect the brake pads for thickness; if less than 3 mm, replace them.
• To replace, remove the caliper bolts, slide the caliper off, and replace the old pads with new ones.
• Reassemble the caliper and wheel, ensuring all nuts are torqued to specifications (typically around 80-100 lb-ft).

4. Repair or Replace Brake Lines

• Tools Required: Brake line tool kit, wrenches.
• Visually inspect all brake lines for leaks or damage.
• If leaks are found, replace the affected sections of the brake line using the appropriate fittings and tools.
• Bleed the brake system after repairs to remove air from the lines.

5. Test the Brake System

• Tools Required: Multimeter.
• Reconnect any electrical connectors you may have disconnected during inspection.
• Turn on the ignition without starting the engine, and check that the brake warning light is off.
• Start the vehicle and press the brake pedal to ensure it feels firm and responsive.
