Normal Operation

The instrument cluster communicates interactively with other electronic modules using the communication network. With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the smart junction box (SJB) through circuits (R/Y), and (P/B). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the SJB through circuit (B/LG). The instrument cluster is grounded through circuits (B) and (B/W).
