Title: SYSTEM FOR PROCESSING OUTPUT SIGNALS ASSOCIATED WITH MULTIPLE VEHICLE CONDITION SENSORS
Abstract:
A system (10) for processing output signals associated with multiple vehicle condition sensors includes a first sensor (26) producing a pair of output signals indicative of a first vehicle condition and a second (28) sensor producing an output signal indicative of a second vehicle condition. One of the first sensor output signals and the second sensor output signals are received by an interface circuit (30) which produces an output signal that is a function of its two input signals. A vehicle control computer (34) receives the output of the interface circuit and the other of the first sensor output signals and processes these signals to provide diagnostic information related to each of the two sensors. The diagnostic information may include fault codes associated with individual ones, or a combination, of the two sensors which are stored in memory (52), and may further include energizing signals for energizing warning means (64, 68) associated with each of the two sensors.
