Test S: The Instrument Cluster Is Inoperative

PINPOINT TEST S: THE INSTRUMENT CLUSTER IS INOPERATIVE

S1:

S2-S3:

Normal Operation
With the ignition switch in the RUN position, the instrument cluster receives voltage from the central junction box (CJB) through circuit 1003 (GY/YE). With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the CJB through circuit 640 (RD/YE). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive battery voltage from the CJB through circuit 1523 (DG). The instrument cluster grounding is through circuits 57 (BK) and 676 (PK/OG).

Possible Causes
- fuse(s)
- circuit 57 (BK) open
- circuit 640 (RD/YE) open
- circuit 676 (PK/OG) open
- circuit 1003 (GY/YE) open
- circuit 1523 (DG) open
- instrument cluster
