Test T: The Instrument Cluster Is Inoperative

PINPOINT TEST T: THE INSTRUMENT CLUSTER IS INOPERATIVE

T1-T2:

T2-T3:

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 3049 (BK/LG). When the ignition switch is in the RUN or ACC position, voltage is received from the SJB through circuit 1002 (BK/PK). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive memory voltage from the SJB through circuit 956 (OG/LG). The instrument cluster grounding is through circuit 570 (BK/WH) and the indicators are grounded through circuit 57 (BK).

Possible Causes
- fuse(s)
- circuit 57 (BK) open
- circuit 570 (BK/WH) open
- circuit 956 (OG/LG) open
- circuit 1002 (BK/PK) open
- circuit 3049 (BK/LG) open
- instrument cluster
