Test A: No Communication With the Instrument Cluster Module

PINPOINT TEST A: NO COMMUNICATION WITH THE INSTRUMENT CLUSTER MODULE

A1:

A2-A3:

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 power from the central junction box (CJB) fuse(s) 4 (5A), circuit 15-GG14 (GN/RD) and 17 (5A), circuit 15-JA14 (GN/BK), when the ignition switch is in the RUN/ACC position, power is received from the CJB fuse 13 (5A), circuit 75-GG15 (YE/GN). With the ignition switch in the OFF position, the instrument cluster receives its power from CJB fuse(s) 20 (10A), circuit 29-GG11 (OG/BU), and 19 (15A), circuit 29-AL12 (OG). The instrument cluster grounding is accomplished through circuit 91-GG11 (BN/RD), and circuit 31-AL11 (BK).

Possible Causes
- circuit 15-GG14 (GN/RD) open
- circuit 15-JA14 (GN/BK) open
- circuit 29-GG11 (OG/BU) open
- circuit 31-AL11 (BK) open
- circuit 75-GG15 (YE/GN) open
- circuit 91-GG11 (BN/RD) open
