PINPOINT TEST AD: THE INSTRUMENT CLUSTER IS INOPERATIVE

Test AD1-AD2:

Test AD2-AD4:

Normal Operation
With the ignition in the START/RUN position, the instrument cluster receives power from the central junction box (CJB) fuse 4 (5A), circuit 15-GG1 (GN/BU) 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 ignition 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 (BK/BU).

Possible Causes
- central junction box (CJB) fuse(s): 4 (5A), 13 (5A), 17 (5A) and 20 (10A)
- circuit 15-GG1 (GN/BU) open or short to ground
- circuit 15-JA14 (GN/BK) open or short to ground
- circuit 75-GG15 (YE/GN) open or short to ground
- circuit 29-GG11 (OG/BU) open or short to ground
- circuit 91-GG11 (BK/BU) open or short to power
- instrument cluster
