Test A: The Instrument Cluster Is Inoperative

PINPOINT TEST A: THE INSTRUMENT CLUSTER IS INOPERATIVE

A1-A2:

A3:

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 1112 (VT), and circuit 640 (RD/YE). The B+ keep alive memory (KAM) voltage is from the SJB through circuit 1001 (WH/YE). The instrument cluster grounding is accomplished through circuits 1203 (BK/LB) and 1205 (BK).

Possible Causes
- Fuse(s)
- Circuit 640 (RD/YE) open
- Circuit 1001 (WH/YE) open
- Circuit 1112 (VT) open
- Circuit 1203 (BK/LB) open
- Circuit 1205 (BK) open
- Instrument cluster
