Tire Pressure Monitor
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The instrument panel cluster (IPC) receives serial data messages from the tire pressure monitoring (TPM) system for the front and rear tire pressure. The driver information center (DIC) displays the pressure for each of the front and rear tires. Tire pressure values are not reset through the DIC.
