Shift Interlock Solenoid: Description and Operation
When the select lever is in "P" range, the ignition key position is "ON" and depressing the brake pedal cause the electric current to flow to the solenoid.
As the lock plate is drawn toward the solenoid in this state, it frees the detent pin, which then allows the select lever to be shifted from "P" range to any
other position.
Even when the select lever is in "P" range, if the ignition key position is "LOCK" or "ACC" or the brake pedal is not depressed, the electric current does
not flow to the solenoid. In this state, the lock plate is pushed away from the solenoid by spring force and it obstructs the detent pin movement. Thus the
select lever button does not work even when pressed and the select lever shift is prevented.
