how to troubleshoot Honda CR-V Sixth Generation (2023-present) ABS light on

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the battery to prevent any electrical shorts during the repair.

2. Inspect and Replace Fuses

• Locate the fuse box under the dashboard or in the engine compartment.
• Remove the fuse related to the ABS system using a fuse puller.
• Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.
• Reconnect the battery.

3. Check Brake Fluid

• Open the hood and locate the brake fluid reservoir.
• Check the fluid level; if it’s low, top it up with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
• Inspect for any leaks in the brake lines or at the calipers.

4. Inspect ABS Wheel Speed Sensors

• Locate each wheel speed sensor; these are typically mounted near the brake rotor.
• Check for any physical damage or disconnections.
• Clean the sensor with brake cleaner if dirty.

5. Test ABS Wheel Speed Sensors

• Using a multimeter, set it to the resistance setting.
• Disconnect the sensor's connector and measure resistance across the terminals; compare with manufacturer specifications (usually around 1,000-2,000 ohms).
• Replace any faulty sensors.

6. Reconnect and Test

• Reconnect all components and the battery.
• Start the vehicle and check if the ABS light remains illuminated.
• Take the vehicle for a test drive to see if the ABS system activates correctly (the ABS light should turn off).
