CIRCUIT OPERATION
Selector Interlock
When the gear selector is in the park position, the
solenoid inside the Transmission Range Selector
Switch (Z110) is de-energized and prevents the
selector from being moved into another gear. To
free the selector, the Ignition Switch (X134) must
be in position II and the brake pedal must be
depressed. When this occurs, voltage from Fuse
F1 is applied to the Transmission Range...
