What is the tire pressure monitoring system of the Tiida?
2 Answers
The Tiida's tire pressure monitoring system is mainly divided into two types, as detailed below: 1. Direct tire pressure monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure. It then transmits the pressure information from inside the tire to a central receiver module via wireless transmitters, displaying the pressure data for each tire. The system automatically alerts when the tire pressure is too low or when there is a leak. 2. Indirect tire pressure monitoring: The working principle of indirect tire pressure monitoring is as follows: when the pressure of 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 rotational speed differences between tires, the system monitors the tire pressure. The indirect tire pressure warning system actually relies on calculating the tire's rolling radius to monitor the pressure.
The Nissan Tiida's tire pressure monitoring system typically adopts an indirect monitoring method. It primarily relies on the vehicle's ABS sensors to detect rotational speed differences among the four wheels, thereby indirectly inferring whether tire pressure is unbalanced. The system principle is: when a tire's pressure is low, changes in its rolling radius cause increased or uneven rotational speed, which the sensors capture, triggering a yellow exclamation mark warning light on the dashboard. This method is cheaper than installing direct sensors and doesn't require replacing tire valve components, but its drawback is lower accuracy, sometimes being falsely triggered by uneven road surfaces or turns. Having driven this car for several years, I found it quite responsive on city roads but occasionally gave false alarms at high speeds. It's recommended that owners manually check tire pressure regularly, especially before seasonal changes or long trips, as the system doesn't display specific pressure values, only alerting to issues. If the light comes on, don't panic—find a safe spot to check the pressure and top up if needed; common issues are usually slow leaks or sensor recalibration needs. Remember, maintaining proper tire pressure prevents blowouts, saves fuel, and extends tire life.
