Indirect TPMS
The Nissan Tire Pressure Monitoring System (TPMS) is a safety feature found on certain Nissan models that helps alert drivers when their tire pressure is low. Under-inflated tires can lead to punctures and reduced grip on slippery surfaces. This can affect handling and fuel efficiency. For this reason, Nissan has introduced a number of vehicles that feature this system.
There are two types of TPMS systems. They are direct and indirect. Direct TPMS uses individual tire pressure sensors that send signals at 315 or 434 MHz. Each sensor broadcasts its own unique ID number, which is registered in the TPMS ECU. If a sensor malfunctions or fails, it will lose its signal and the warning light will go off.
Indirect TPMS, however, relies on a more advanced module to detect low tire pressure. Because this type of system does not require additional hardware or service procedures, it can save consumers money in the long run. As a result, indirect TPMS is becoming more popular. Many models, including the Volkswagen Golf, the Mazda CX-5, and the Honda Accord, have adopted indirect TPMS. These models are available as standard or as optional equipment.
Some TPMS systems can send the same message to several sensors, which can cause an issue. The vehicle may malfunction if the system gets confused. A good way to find out if there’s a problem is to check the battery level of the TPMS sensors. It can be checked during routine maintenance, and some manufacturers recommend replacing them at the same time as new tires are installed.
Some TPMS systems have a warning light that comes on when a tire’s pressure drops below 75 percent of its recommended level. These systems are equipped with a “learn mode” that lets the ECU learn by activating the sensor in a predetermined sequence. Most sophisticated TPMS have a display that indicates which tire is low. However, these types of systems can also have real-time tire pressure readings that can be viewed on a driver information center.
While a TPMS system can help drivers avoid under-inflated and over-inflated tires, it can only do so much. Ultimately, the best strategy is to keep a close eye on your tires. That way, you can ensure that you’re never in a situation where you’re driving on an under-inflated or over-inflated tire. Also, if you’re planning on purchasing a set of new tires, it’s important to make sure they’re a match for your current tires. Over-inflated tires can cause a blowout and reduced traction on the road.
One of the key features of TPMS systems is that they can be used in conjunction with the vehicle’s Antilock Braking System (ABS). When a vehicle’s ABS is disabled, an indirect TPMS can still monitor the wheel speed and alert the driver when a tire’s pressure is low.
Whether you have an indirect or direct TPMS, you should regularly monitor the tire’s pressure. Even if your tires are in excellent condition, you should make sure they are properly inflated. Properly inflated tires can reduce the likelihood of a blowout and improve fuel efficiency. Additionally, under-inflated tires can wear unevenly and create a reduction in braking, cornering, and grip.
