Why does the Sagitar tire pressure monitoring light keep flashing and cannot be reset?
2 Answers
Sagitar tire pressure monitoring light keeps flashing and cannot be reset due to reasons such as the tire pressure sensor being out of power or damaged, incorrect tire pressure light reset method, or multimedia damage or touch screen malfunction. Tire pressure sensor out of power or damaged: Use professional equipment to remove the tire, take out the tire pressure sensor, and test its voltage with a multimeter to see if it has power. If there is power, the tire pressure sensor may be damaged. Replace the tire pressure sensor battery or the tire pressure sensor itself. The tire pressure sensor is free of charge during the warranty period. Incorrect tire pressure light reset method: If the reset is not performed according to the correct method, the tire pressure light cannot be reset. Use the correct reset method to resolve the issue. Multimedia host damage or touch screen malfunction: If the multimedia host is damaged or the touch screen malfunctions, it may prevent normal operation during the reset process. Timely replacement is necessary. Tire pressure reset is an operation performed on the tire pressure monitoring system after the tire pressure fault has been resolved to reset the system. Tire pressure reset method: First, turn on the ignition switch, press and hold the tire pressure monitoring reset button until you hear a "beep" sound, then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the fault light on the dashboard will turn off, indicating the completion of the tire pressure reset.
My Sagitar recently had this annoying issue where the tire pressure monitoring light kept flashing and wouldn't reset. That day, the tire pressure looked normal, but the light just wouldn't go off. Through trial and error, I figured out several possible causes: when temperatures drop, tire pressure naturally decreases slightly, which can trigger false alarms in the system; or the sensor battery might be dead and can't transmit signals, causing the light to flash continuously; it could also be that the system needs proper resetting, and incorrect operations won't fix it. Here's what I tried: first, check the pressure in all tires, measuring each one to ensure they meet the manual's standard (like 2.5Bar); if everything's fine, drive at about 40 km/h for five minutes to let the system auto-calibrate; if that doesn't work, park and start the car, then hold the SET button on the steering wheel for five seconds to try resetting. If the light keeps flashing after all this, head straight to the 4S shop for a professional check—don't skimp on this. This might seem like a minor issue, but ignoring it could lead to dangerous tire blowouts and compromise driving safety.
