Print

Description & Operation



In the RUN position, the ignition switch connects power from the Power Distribution Center (PDC) to a fuse in the fuse block, back to a bus bar in the PDC. The bus bar feeds circuits for the Powertrain Control Module (PCM), Proportional purge solenoid, EGR solenoid, and ABS system. The bus bar in the PDC feeds the coil side of the radiator fan relay, A/C compressor clutch relay, and the fuel pump relay. It also feeds the Airbag Control Module (ACM). The ignition switch attaches to the lock cylinder housing on the end opposite the lock cylinder.
