How to Match the Tire Pressure Sensor of Refine M4?

[Max]

Inflate the tire pressure of Refine M4 to the normal range, conduct a road test, maintain the speed above 25 mph, and drive for at least 15 minutes to complete the automatic matching. Alternatively, you can use professional diagnostic equipment to input the sensor ID number into the vehicle's computer for matching. Tire Pressure Monitoring: Tire pressure monitoring is the real-time automatic monitoring of tire pressure during vehicle operation, with alerts for tire leaks and low pressure to ensure driving safety. Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data is displayed. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the speed differences between tires, the system monitors tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above, equipping direct sensors in two diagonally opposite tires and incorporating a 4-wheel indirect system. Compared to using only direct systems, this hybrid system can reduce costs and overcome the limitation of indirect systems in detecting simultaneous low pressure in multiple tires. However, it still cannot provide real-time data of the actual pressure in all four tires as a direct system does.

I remember last year when I replaced the new sensor on my Refine M4, the matching process was actually quite simple. First, start the vehicle and ensure the engine is running normally, then enter the learning mode: the Refine M4 usually has a dedicated button under the steering wheel or on the side of the dashboard. Press it, and the tire pressure light on the dashboard will flash. Next, I took out the diagnostic device (like a regular OBD scanner) from the toolkit, triggered each sensor one by one for every tire, or used the deflation method: slightly loosen the air to let the pressure drop for a few seconds and then refill it, and the vehicle would automatically recognize the new sensor. After matching, check again to see if the light goes off, then drive for a few minutes to confirm the system is stable. The whole process took about 15 minutes, but it’s important to follow the method recommended in the manual; otherwise, it might fail and affect safety. Why is matching necessary? Without matching, the car would keep giving false alarms, making you nervous while driving.
