PINPOINT TEST AG: THE INSTRUMENT CLUSTER IS INOPERATIVE

AG1-AG2:

AG2-AG4:

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 CBP29 (WH/VT). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from the SJB through circuit SBP26 (YE/RD). The instrument cluster grounding is through circuit GD133 (BK).

Possible Causes
- Fuse(s)
- Circuit CBP29 (WH/VT) open or short to ground
- Circuit SBP26 (YE/RD) open or short to ground
- Circuit GD133 (BK) open
- Instrument cluster
