A low voltage condition could cause those warnings like Archon stated. There are other functions on the DIC that maybe should have annunciated also, but who knows. The Service Stability & Tire pressure warnings both originate at the EBCM and are sent to the Instument Panel Cluster (IPC) via serial data bus to turn on the warnings The Battery Low warning is generated when the system voltage is less than 10.5 vdc. The Dash Integration Module (DIM) communicates battery voltage to the IPC via serial data bus. Anyway, if no more mystery warnings come in, then I'd say the battery could have been the culprit. Make sure all battery cables/connections are clean & tight both ends, under protective boots also.
