Test V: The Instrument Cluster Is Inoperative

PINPOINT TEST V: THE INSTRUMENT CLUSTER IS INOPERATIVE

V1-V3:

Normal Operation
With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the smart junction box (SJB) through circuits 640 (RD/YE), and 489 (PK/BK). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the SJB through circuit 3049 (BK/LG). The instrument cluster is grounded through circuits 57 (BK) and 570 (BK/WH).

Possible Causes
- fuse(s)
- circuit 57 (BK) open
- circuit 489 (PK/BK) open
- circuit 570 (BK/WH) open
- circuit 640 (RD/YE) open
- circuit 3049 (BK/LG) open
- instrument cluster
