Test AF1-AF2:

Test AF2-AF4:

Normal Operation
The instrument cluster receives the START/RUN power from the CJB fuse 21 (5A), circuit 489 (PK/BK). The RUN/ACC power is from the CJB fuse 15 (5A), circuit 295 (LB/PK) and the keep-alive power from the BJB fuse 15 (15A), circuit 3049 (BK/LG). The instrument cluster grounding is accomplished through circuit 1203 (BK/LB) and the bulb grounding is accomplished through circuit 1205 (BK).

Possible Causes
- circuit 295 (LB/PK) open or shorted to ground
- circuit 489 (PK/BK) open or shorted to ground
- circuit 1203 (BK/LB) open or shorted to power
- circuit 1205 (BK) open or shorted to power
- circuit 3049 (BK/LG) open or shorted to ground
