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 central junction box (CJB) through circuit 15-GG14 (GN/RD). With the ignition switch in the RUN or ACC position the instrument cluster receives voltage from the CJB through circuit 75-GG14 (YE/BU). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the CJB through circuit 29-GG14 (OG). The instrument cluster is grounded through circuit 91-GG14 (BK/OG).
