Normal Operation

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The warning chime is an integral part of the instrument cluster. The instrument cluster sounds the warning chimes after receiving hardwired and data signal inputs from various sources. Data input signals are transmitted to the instrument cluster over the (UART)-based protocol (UBP) communication network, circuit 1906 (PK).
