Circuit Description

WARNING: This page is about a different car, the 2003 Buick Regal and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster receives a vehicle speed input from the vehicle speed sensor (VSS) over the class 2 line from the PCM. This signal is used in order to drive the speedometer and the odometer of the instrument cluster. The season odometer displays the total accumulated kilometers (miles) of the vehicle and stores the value permanently in the electronically erasable programmable read only memory (EEPROM) of the instrument cluster. The trip odometer displays the accumulated kilometers (miles) to the tenths of a kilometer (mile) since the last reset and stores the value in the keep alive memory (KAM) of the instrument cluster.
