TIRE PRESSURE MONITORING SYSTEM PROCEDURES FOR 2007 Hummer H3 AUTOMOBILES
Description
Vehicle: 2007 Hummer H3 3.7 L5 GAS
The TPMS (Tire Pressure Monitor System) notifies the driver when a significant loss of tire pressure occurs in any of the four tires.
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 reading once every ...
