Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, cleaning supplies.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Remove the wheel on the affected corner to access the wheel speed sensor.
Use a multimeter to check the resistance of the wheel speed sensor; the typical range should be around 1,000 to 1,500 ohms.
Clean the sensor and its mounting surface if dirt or debris is present.
Reinstall the wheel and torque to the manufacturer’s specifications (usually around 76 ft-lbs for RAV4).

3. Check ABS Module and Wiring

Locate the ABS module under the hood and visually inspect for any signs of damage or corrosion.
Use the OBD-II scanner to retrieve and clear any fault codes related to the ABS or traction control system.
Inspect wiring harnesses for wear or disconnections, particularly around the ABS module and wheel speed sensors.

4. Test Brake Pedal Switch

Locate the brake pedal switch and check for proper operation.
Use a multimeter to ensure the switch is functioning correctly; it should show continuity when the brake pedal is pressed.
Replace the switch if it is malfunctioning.

5. Verify Traction Control Switch

Check the traction control switch located on the dash for proper function.
Ensure the switch is not stuck or damaged; replace if necessary.
