What are the reasons why the vv7 tire pressure check does not display?

If there is a response when static but not while driving, it may be due to one of three reasons: low transmission strength, receiver issues, or insufficient sensitivity causing interference. If there is no response when static and pairing fails, then the transmitter is faulty. Low signal transmission strength causing this issue can usually be resolved by changing the placement location. Specific reasons and measures are as follows: 1. The module battery is depleted, generally requiring replacement of the entire tire pressure monitoring module. 2. The module inspection port is blocked, preventing the module from performing the detection. 3. Pairing failure, requiring re-pairing. Some vehicle models can complete this themselves, but most models require professional pairing at a 4S shop. 4. The module is damaged and can only be replaced with a new one.
As a VV7 owner, I've encountered the issue of tire pressure monitoring not displaying, which is quite annoying. The most common reason is the TPMS sensor battery running out, as those things inside the tires tend to last only five or six years. Additionally, if the vehicle recently had tire or sensor replacements, incomplete system pairing can also cause this. In extreme weather conditions like cold temperatures causing low tire pressure, system updates might be delayed, leading to no display. My suggestion is to manually check the actual tire pressure with a gauge just in case, then visit the dealership to scan for fault codes with a diagnostic tool. They can determine whether it's a faulty sensor or interference with the receiving module. Safe driving relies on this function, so don't delay addressing it to avoid potential accidents on highways.
I know a bit about automotive electronics. The issue of the VV7's tire pressure check not displaying usually involves signal transmission problems. The built-in sensors might be clogged with dirt, affecting readings, or the antenna could be positioned too far away, preventing data from reaching the central control screen. Software bugs are also a common cause, such as compatibility issues after a system update—sometimes restarting the vehicle can fix this. Short battery life is a major drawback; if you can't check it yourself, it's best to refer to the manual for reset steps. Don't underestimate this issue—prolonged neglect could lead to tire pressure alarm failure, increasing the risk of a blowout. Addressing it early saves both money and hassle.
