how to address the ABS light on my Toyota RAV4 Fifth Generation (2019-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the battery to avoid any electrical shorts while working on the ABS system.

2. Inspect and Clean Wheel Speed Sensors

• Tools Required: Ratchet and socket set, multimeter.
• Remove each wheel to access the wheel speed sensors.
• Disconnect the wheel speed sensor connector.
• Use a multimeter to test the sensor's resistance (should be within manufacturer specifications).
• Clean any dirt or debris from the sensor and mounting area using a suitable cleaner.
• Reinstall the sensor and reconnect the electrical connector.

3. Check ABS Fuse

• Locate the fuse box; refer to the owner’s manual for the specific location of the ABS fuse.
• Remove the ABS fuse and check for continuity using a multimeter.
• If the fuse is blown, replace it with a fuse of the same amperage and type.

4. Brake Fluid Check and Replacement

• Tools Required: Brake fluid, funnel.
• Inspect the brake fluid level in the master cylinder reservoir.
• If low, top off with the appropriate type of brake fluid (usually DOT 3 or DOT 4).
• If the fluid is contaminated, perform a brake fluid flush to replace old fluid.

5. ABS Module Reset

• After repairs, connect the battery and use an OBD-II scanner to clear any stored ABS codes.
• Perform a test drive to ensure the ABS light does not illuminate again.
