SERVICING GM TIRE PRESSURE MONITORING SYSTEMS

摘要

ON SOME 2018 TO CURRENT BUICK MODELS, GM USED CONTINENTAL'S CONTISILENT TIRES. THE FOAM REDUCES NOISE, BUT CAN BE EXPENSIVE TO REPLACE IF DAMAGED BY UNDER INFLATION. The initial "low tire" light is similar to the "low fuel" indicator and adding air to the low tire will extinguish the light. If the driver re-inflates the low tire, they must drive a short distance for at least 30 seconds before the sensors recognize the increase in pressure and turn the light off again. If the deflation is rapid, it will give a more immediate warning by flashing the warning light. A GM TPMS sensor includes pressure, temperature and acceleration functions. The unit also has a radio transmitter, receiver and battery. Sensors have a 10 year/150,000 mile (240,000 km) battery life.
