If your vehicle was manufactured after 2007, it is equipped with a Tire Pressure Monitoring System (TPMS). The TPMS indicator will illuminate on your vehicle's dashboard when the tire air pressure falls below the recommended level by 25% or more.
Should you observe the TPMS warning on your vehicle's dashboard, immediately check your tire pressure or stop by one of our stores to air up your tires to the recommended pressure and conduct a thorough examination for any signs of damage.
Indirect TPMS (iTPMS) systems do not use physical pressure sensors; they measure air pressures using software-based systems, which by evaluating and combining existing sensor signals such as wheel speeds, accelerometers, and driveline data to estimate and monitor the tire pressure
Direct TPMS (dTPMS) directly measures tire pressure using hardware sensors. In each wheel, mostly on the inside of the valve, there is a battery-driven pressure sensor which transfers pressure information to a central control unit.
Pressure sensor or TPMS sensor belongs to dTPMS. I would say Autel MX Sensor works well and it widely available in the market, following is the description of this product.

Although TPMS provides valid feedback in monitoring your tire pressure, it should not get rid of monthly air pressure checks. Both types of TPMS only alert when the tire pressure drops below the recommended reading by 25%.
This is a high threshold as tires that are underinflated by just 5% begin to suffer from increased internal temperatures and decreased fuel economy. These issues become more pronounced while your tires actually be underinflated yet without triggering a TPMS alert.
For this reason, you should never rely solely on TPMS to monitor your tire pressure. Always use a reliable gauge to manually check it each month. The TPMS functions as a warning that complements an existing safety routine and is not a first line of defense.
SRS airbags are safety devices installed in vehicles to protect the driver and passengers during a crash. Unlike traditional seatbelts, airbags are designed to rapidly inflate during a collision to cushion the impact of the occupants' bodies, reducing the likelihood of serious injury.
The main cause of parking brake malfunction is to short circuit or open circuit of the wires or circuits between the switch, controller, and actuator. When the brake system fails, the brake light on the dashboard will activate so the driver can detect the problem to repair it.
Modern vehicles are becoming increasingly complex, incorporating advanced systems like driver-assistance technologies, electronic control units (ECUs), and hybrid powertrains. AI bridges the gap by analyzing large volumes of data from a car’s onboard systems, helping mechanics pinpoint knots.
