Test X: The Instrument Cluster Is Inoperative
PINPOINT TEST X: THE INSTRUMENT CLUSTER IS INOPERATIVEX1-X3:
Normal Operation
With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the smart junction box (SJB) through circuit 1566 (RD/YE). When the ignition switch is in the RUN or ACC position, voltage is received from the SJB through circuit 295 (LB/PK). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the SJB through circuit 483 (RD). The instrument cluster grounding is accomplished through circuit 1203 (BK/LB) and the circuit 1205 (BK).
Possible Causes
- fuse(s)
- circuit 295 (LB/PK) open
- circuit 483 (RD) open
- circuit 1203 (BK/LB) open
- circuit 1205 (BK) open
- circuit 1566 (RD/YE) open
- instrument cluster
