PINPOINT TEST AE: THE INSTRUMENT CLUSTER IS INOPERATIVETest AE1-AE2:
Test AE3-AE4:
Normal Operation
With the key 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), while in the RUN/ACC position, power is received from the CJB fuse 13 (5A), circuit 75-GG15 (YE/GN). With the key in the OFF position, the instrument cluster receives its keep-alive power from the CJB fuse 20 (10A), circuit 29-GG11 (OG/BU). The instrument cluster grounding is accomplished through circuit 91-GG11 (BN/RD).
Possible Causes
