Test B: No Power in ACC

Pinpoint Test B: No Power In ACC
Refer to Vehicle/Diagrams, Power Distribution/SJB for schematic and connector information.

Normal Operation
The battery junction box (BJB) receives battery power at all times through circuit 973 (RD). The BJB then provides the ignition switch with fused battery power through fuse 7 (40A) circuit 1050 (LG/VT). When placed in ACC, the ignition switch provides voltage to the smart junction box (SJB) fuses 22 (15A) and 23 (30A) through circuit 297 (BK/LG). SJB fuse 22 (15A) provides fused ignition power to the integrated control panel and the instrument cluster, SJB fuse 23 (30A) provides fused ignition power to the windshield wiper motor, the wiper HI/LO relay (in the BJB) and the wiper PARK/RUN relay (in the BJB).

Possible causes
^ Fuse(s)
^ Open circuit
^ Ignition switch
