Test X: The Instrument Cluster Is Inoperative

PINPOINT TEST X: THE INSTRUMENT CLUSTER IS INOPERATIVE

X1-X3:

Normal Operation
The instrument cluster communicates interactively with other electronic modules using the communication networks. With the ignition switch in the START/RUN position, the instrument cluster receives power from the smart junction box (SJB) fuse 20 (7.5A), circuit 1566 (RD/YE). When the ignition switch is in the RUN/ACC position, power is received from the SJB fuse 23 (7.5A), circuit 295 (LB/PK). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive power from the SJB fuse 7 (7.5A), circuit 483 (RD). The instrument cluster grounding is accomplished through circuit 1203 (BK/LB) and the circuit 1205 (BK).

Possible Causes
- circuit 295 (LB/PK) open
- circuit 1566 (RD/YE) open
- circuit 1203 (BK/LB) open
- circuit 1205 (BK) open
- circuit 483 (RD) open
- instrument cluster
