Z1-Z3:

Z3-Z4:

Normal Operation
With the ignition switch in the START/RUN position, the instrument cluster receives power from the central junction box (CJB) fuse(s) 4 (5A), circuit 15-GG14 (GN/RD), and 17 (5A), circuit 15-JA14 (GN/BK). With the ignition switch in the RUN/ACC position, power is received from the CJB fuse 13 (5A), circuit 75-GG15 (YE/GN). With the ignition switch in the OFF position, the instrument cluster receives its power from the CJB fuse 20 (10A), circuit 29-GG11 (OG/BU). The instrument cluster grounding is accomplished through circuits 91-GG11 (BN/RD) and 31-AL11 (BK).

Possible Causes
- circuit 15-GG14 (GN/RD) open
- circuit 15-JA14 (GN/BK) open
- circuit 29-GG11 (OG/BU) open
- circuit 31-AL11 (BK) open
- circuit 75-GG15 (YE/GN) open
- circuit 91-GG11 (BN/RD) open
- instrument cluster
