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 the diagnostic tool and other electronic modules using the controller area network (CAN). With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the smart junction box (SJB) through circuit CBP20 (YE/VT). When the ignition switch is in the RUN or ACC position, voltage is received from the SJB through circuit CBP23 (BN/YE). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the SJB through circuit SBP07 (WH/RD). The instrument cluster grounding is through circuit GD116 BK/VT).

Possible Causes
- fuse(s)
- circuit CBP20 (YE/VT) open
- circuit CBP23 (BN/YE) open
- circuit GD116 (BK/VT) open
- circuit SBP07 (WH/RD) open
- instrument cluster
