Test A: No Communication With The Instrument Cluster

PINPOINT TEST A: NO COMMUNICATION WITH THE INSTRUMENT CLUSTER

A1-A2:

Normal Operation
The instrument cluster communicates interactively with other electronic modules using the communication network. With the ignition switch in the START/RUN position, the instrument cluster receives voltage from the smart junction box (SJB) fuse 16 (5A), circuit 489 (PK/BK), and SJB fuse 19 (5A) circuit 1266 (RD/YE). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the SJB fuse 8 (10A), circuit 1001 (WH/YE). The instrument cluster is grounded through circuit 1205 (BK).

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