PINPOINT TEST Y: THE INSTRUMENT CLUSTER IS INOPERATIVE

Y1-Y2:

Y3:

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 489 (PK/BK), and 1266 (RD/YE). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the SJB through circuit 1001 (WH/YE). The instrument cluster is grounded through circuit 1205 (BK).

Possible Causes
- fuse(s)
- circuit 489 (PK/BK) open
- circuit 1001 (WH/YE) open
- circuit 1205 (BK) open
- circuit 1266 (RD/YE) open
- instrument cluster
