TIRE PRESSURE MONITORING SYSTEM PROCEDURES FOR 2004 Buick Lesabre AUTOMOBILES
Description
Vehicle: 2004 Buick Lesabre Limited 3.8 V6 GAS
The TPMS (Tire Pressure Monitor System) alerts the driver when a large change in the pressure of one tire exists. The system detects a tire pressure condition while the vehicle is in motion, once a tire pressure condition is detected, the system alerts the driver whenever the ignition is turned On. The TPMS uses the EBCM (Electronic Brake Control Module), ABS (Anti-Lock Brake System) wheel speed sensor inputs, serial data circuit and the DIC (Driver Information Center) to perform the system functions. The EBCM contains software to calculate relative tire pressure differences. The so...
