Low Tire Pressure
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
Tire pressure is based on the information the DIC receives from a class 2 message from the EBCM. The DIC displays NORMAL when the tire pressure is normal. When there is low tire pressure, the DIC displays LOW TIRE PRESSURE HOLD SET TO RESET. In order to reset the low tire pressure, press and hold the Set button for 3 seconds. When the tire pressure has been reset, the DIC displays TIRE PRESSURE RESET for 3 seconds.
