What does the C102D00 tire pressure warning mean?

[DeBeau]

C102D00 indicates a tire pressure warning, requiring immediate inspection and adjustment of tire pressure. The method to reset the tire pressure alarm is as follows: First, turn on the ignition, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. Precautions for inflating tires: Always use a pressure gauge to check the pressure to avoid overinflation, which could cause the tire to burst. After stopping the vehicle, wait for the tires to cool down before inflating, as driving increases tire temperature, affecting pressure readings. Inspect the valve stem. If the valve stem and core are not properly aligned, have protrusions, depressions, or other defects, it may hinder inflation and pressure measurement. Ensure cleanliness during inflation. The air being pumped in should not contain moisture or oil, as this could deteriorate the inner tube rubber. Avoid inflating beyond the standard pressure and then deflating, or overinflating after prolonged periods without inflation. Exceeding the standard pressure excessively can overstretch the cords, reducing their strength and affecting the tire's lifespan.
