What is the tire pressure monitoring system of the Tiida?

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.
I once owned a Tiida as a daily commuter, which came with an indirect tire pressure monitoring system. Simply put, it doesn't measure pressure directly but estimates leaks by detecting rotational speed differences between wheels. While driving, a warning light flashes on the dashboard to indicate potential issues. After using it for a year or two, I found the system quite thoughtful—like detecting low pressure during winter morning drives once reaching speed. However, it has minor flaws, such as false alarms on slippery roads or during sharp turns, prompting me to pull over for manual checks. New owners shouldn't fret over occasional false alerts; keeping a handheld tire pressure gauge in the car helps. Maintenance is straightforward, requiring only biannual wheel alignment checks at the dealership. Remember, incorrect tire pressure not only wastes fuel but also increases braking distance—safety first. Though not premium, this feature in the Tiida is practical enough to offer peace of mind during commutes.
When driving a Tiida on long trips, I noticed its tire pressure monitoring is indirect, based on wheel speed sensors. The system uses ABS sensors to detect rotational speed differences, triggering the warning light. It's accurate on smooth roads but prone to false alarms on bumpy surfaces or sharp turns. I've dealt with several warning light incidents, usually resolved by adding some air. Proper tire pressure can reduce fuel consumption by 10% and prevent abnormal tire wear. I recommend owners develop the habit of manually checking pressure monthly.
