Normal Operation
With the ignition switch in the START/RUN positions, the instrument cluster receives voltage from the smart junction box (SJB) through circuit 1566 (RD/YE). When the ignition switch is in the RUN/ACC positions, 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 provided through circuits 1203 (BK/LB) and 1205 (BK).

Possible Causes
- Fuse
- 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
