Automatic Transmission

CIRCUIT OPERATION
The Power Distribution Center ([1][2]PDC) supplies battery voltage to the starter motor solenoid through circuit T40 when the coil side of the starter motor relay energizes. Circuit A1 supplies battery voltage to the contact side of the relay. Circuit A1 and circuit T40 are protected by a 30 Amp fuse and feeds the contact side of the starter motor relay Both the 30 Amp fuse and the engine starter motor relay are located in the PDC.

The ignition switch supplies battery voltage to the coil side of the starter motor relay on circuit A41 when the key is moved to the START position and the [1][2]park/neutral switch is CLOSED. Ground for the coil side of the starter motor relay is supplied by the park/neutral switch which is case grounded.

Circuit A0 (battery positive cable) supplies battery voltage to the motor of the starter when the solenoid energizes.
