Why does the Haval H2 not display tire pressure numbers after starting?

Haval H2 tire pressure monitoring not displaying is mostly due to a dead battery or a malfunction in the tire pressure detection system. It is recommended to go to a 4S shop for inspection and repair. The Great Wall Haval H2 tire pressure monitoring can be viewed by paging up and down through the function keys on the steering wheel. The role of tire pressure monitoring: The role of tire pressure monitoring is to automatically monitor the tire pressure in real time during driving, and to alert the driver in case of tire leaks or low pressure to ensure driving safety. Classification of tire pressure monitoring: Tire pressure monitoring is mainly divided into two types: indirect tire pressure monitoring (Wheel-Speed Based TPMS, abbreviated as WSB) and direct tire pressure monitoring (Pressure-Sensor Based TPMS, abbreviated as PSB). There is also a composite TPMS.

Last time I drove out, after starting my Haval H2, I noticed the tire pressure display showed no numbers. I've encountered this several times before, mainly due to possible sensor battery depletion or system initialization issues. The tire pressure system relies on small sensors to transmit data wirelessly, and the battery can run out after prolonged use, causing the display to stop responding. Or if you've just changed tire positions, the system needs to be rematched. Try driving for a few minutes—sometimes it returns to normal after a while. Safety first, unclear tire pressure can easily lead to accidents. My experience is to check the sensor battery life during regular maintenance. If there's no improvement, take it to a repair shop to debug the module. Don't ignore it—this affects driving stability and fuel consumption. I recommend using an onboard instrument to measure the pressure and confirm if the values are normal.

As a seasoned car enthusiast, I believe the absence of tire pressure readings after starting a Haval H2 is mostly due to sensor failure or electrical circuit issues. The batteries in the sensors typically need replacement every few years; insufficient voltage prevents signal transmission. System-wise, sometimes the software requires time to read tire data after startup, and driving a few kilometers might update the readings. Troubleshooting method: First, manually check the pressure of all four tires with a tire pressure gauge. If readings are normal, the sensors might be faulty. Resetting the system is straightforward: press the reset button on the dashboard or access the menu to reset the tire pressure monitoring system. If that doesn't work, professional tools are needed to test the circuits or replace components. Ignoring this issue can affect fuel efficiency balance and even accelerate tire wear.

The absence of tire pressure display is critical. If the numbers are blank after starting the Haval H2, I believe weak sensor connection or external interference is the main cause. Aging sensor batteries are the most common issue, especially after prolonged vehicle use. Additionally, low temperatures may cause signal delays. Operationally, start the car and wait a few minutes for the system to self-check to see if it recovers. From a safety perspective, inaccurate tire pressure increases the risk of a blowout, so the pressure values must be confirmed immediately. It is recommended to visit a 4S store to check for hardware faults. Early intervention can save money and prevent major repairs.
