Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, jack, jack stands, socket set, torque wrench, TPMS reset tool (if applicable).
Safety Warnings: Ensure the vehicle is parked on a level surface and the engine is turned off before beginning work.

2. Replace TPMS Sensors (if necessary)

Lift the Vehicle:
- Use a jack to lift the vehicle securely and place jack stands underneath for safety.
Remove Wheel:
- Use a socket set to remove the lug nuts and take off the wheel where the TPMS sensor is suspected to be faulty.
Remove the Old Sensor:
- Unscrew the valve stem nut and gently pull the TPMS sensor out of the tire.
Install New Sensor:
- Insert the new TPMS sensor through the valve stem hole, securing it with the nut. Ensure it is properly seated.
Reinstall Wheel:
- Place the wheel back on the hub and hand-tighten the lug nuts. Use a torque wrench to tighten the lug nuts to the manufacturer specification (typically 76 ft-lbs for RAV4).
Repeat for Other Wheels: If multiple sensors are faulty, repeat the above steps for each affected tire.

3. Reset the TPMS System

Turn on Ignition: Without starting the engine, turn the ignition key to the "ON" position.
Press TPMS Reset Button: Locate the TPMS reset button (often under the steering wheel) and press it until the TPMS light blinks three times, indicating the reset is successful.
Drive the Vehicle: Drive the vehicle for at least 10 minutes at speeds above 15 mph to allow the system to recalibrate.
