Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the 12V battery to prevent electrical issues while working on the TPMS.

2. Check Tire Pressures

Use a reliable tire pressure gauge to measure the pressure of each tire.
Inflate tires to the recommended pressure if they are below specifications.
If any tire is significantly low, inspect for leaks or damage.

3. Inspect TPMS Sensors

Remove the tire from the wheel if necessary to access TPMS sensors.
Visually inspect the sensors for damage or corrosion; replace if damaged.
Ensure that the sensors are properly seated and not loose.

4. Reprogram or Replace TPMS Sensors

If sensors are malfunctioning, use a TPMS tool to reprogram them to the vehicle.
If sensors are confirmed faulty, replace them with new, compatible TPMS sensors.
Ensure to follow the manufacturer's instructions for programming new sensors.

5. Reset TPMS System

Reconnect the 12V battery.
Use the vehicle touchscreen to navigate to the TPMS settings and perform a reset.
Confirm that the system acknowledges the reset and re-checks the tire pressures.
