What symbol represents the tire pressure monitoring button?
1 Answers
The tire pressure monitoring indicator is a partially enclosed exclamation mark on the vehicle's dashboard. Below are specific details about tire pressure monitoring: 1. The tire pressure monitoring system utilizes the ABS sensing function to compare the rotation counts of tires. When tire pressure is insufficient, the tire circumference shortens, resulting in different rotation counts compared to other tires during driving. 2. Tire pressure monitoring relies on wheel speed sensors to detect and alert based on rotational speed differences. Tire pressure can be checked using a pressure gauge. During driving, the system monitors tire inflation pressure. If the inflation pressure in any tire is significantly lower than others, the system triggers an alert. When internal tire pressure decreases, the wheel's effective radius changes, consequently altering its rotational speed. 3. To obtain accurate tire fault information, the system requires tires to maintain proper initial pressure. Initialization must be performed after each tire pressure adjustment, tire replacement, wheel replacement, or when towing vehicles/trailers in trailer mode.
