ABSTRACT:
A monitoring and display system for enunciating warning signals on the vehicle's master display system when the master ignition switch is off. Operational-type signals and warning-type signals are generated by respective sensors throughout the vehicle. A warning controller, responsive to receiving the warning signals and sensing that the ignition switch is off, actuates an alternate path for supplying power to the master display system and controller, which process and display the warning signals under normal processing protocol. However, the warning controller also deactuates the portion of the master display system and controller that normally would display operational signals. In this manner safety related warning signals, and not the normal operating signals, will be displayed to the driver on the master display system of the vehicle even when the ignition switch is off.
