TIRE PRESSURE MONITORING SYSTEM PROCEDURES FOR 2007 GMC Acadia AUTOMOBILES
Description
Vehicle: 2007 GMC Acadia SLE 3.6 V6 GAS
The TPMS (Tire Pressure Monitor System) warns the driver when a significant loss, or gain of tire pressure occurs in any of the four tires and allows the driver to display the individual tire pressures and the locations on the DIC (Driver Information Center) display.
When the vehicle is stationary, the sensor is inactive. When the vehicle is operated and as the vehicle speed increases, centrifugal force activates the sensors internal accelerometer causing the sensors to go into rolling mode. In the rolling mode, the sensors read tire pressure once every 30 second and transmit the rea...
