Circuit Description

The oscillator is a device used in the instrument cluster in order to send and interpret data between the other components along the class 2 serial data line. The major function of the oscillator is to send or receive the different binary (bytes) information between the instrument and the other components within the vehicle. When the ignition switch is first turned On, the instrument cluster performs an internal test on the oscillator. This test determines the integrity of the instrument cluster operation.
