how to fix the ABS light on my Toyota RAV4 XA50 (2019-2024)

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and secure it with wheel chocks.
• Disconnect the negative terminal of the battery to ensure safety.

2. Check Fluid Level

• Locate the master cylinder reservoir under the hood.
• Remove the cap and check the brake fluid level; top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
• Reinstall the cap securely.

3. Inspect ABS Sensors

• Remove the wheel covering the ABS sensor.
• Disconnect the ABS sensor connector and inspect for corrosion or damage.
• Use a multimeter to check the resistance of the sensor. Replace if it falls outside the manufacturer's specified range.

4. Repair or Replace Components

• If any wiring is found damaged, repair by soldering or replacing the harness.
• For faulty ABS sensors, replace them with OEM parts.
• If the ABS module is faulty, consider replacing it or having it professionally rebuilt.

5. Reconnect Battery and Clear Codes

• Reconnect the negative terminal of the battery.
• Use the OBD-II scanner to clear any stored ABS trouble codes.
• Ensure all connections are secure.

6. Test Drive

• Conduct a test drive to ensure the ABS system functions correctly and the light does not reappear.
