Test W: The Instrument Cluster Is Inoperative
PINPOINT TEST W: THE INSTRUMENT CLUSTER IS INOPERATIVEW1-W2:
W2-W3:
Normal Operation
With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the central junction box (CJB) through circuit 1044 (WH/YE). When the ignition switch is in the RUN or ACC position, voltage is received from the CJB through circuit 295 (LB/PK). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the CJB through circuit 729 (RD/WH). The instrument cluster grounding is through circuit 938 (BK/LG) and circuit 57 (BK).
Possible Causes
- fuse(s)
- circuit 57 (BK) open
- circuit 295 (LB/PK) open
- circuit 729 (RD/WH) open
- circuit 938 (BK/LG) open
- circuit 1044 (WH/YE) open
- instrument cluster
