Test AG2-AG4:
Normal Operation
The instrument cluster receives the START/RUN power from central junction box (CJB) fuse 21 (5A), circuit 489 (PK/BK). The RUN/ACC power is from CJB fuse 15 (5A), circuit 295 (LB/PK) and the keep-alive power from the battery junction box (BJB) fuse 49 (15A), circuit 3049 (BK/LG). The instrument cluster grounding is accomplished through circuit 1203 (BK/LB) and the bulb grounding is accomplished through circuit 1205 (BK).
