Shift Interlock: Description and Operation

When the Ignition SW is turned to ACC position the current from the ACCfuse flows to TERMINAL 1 of the shift lock control computer, in the ONposition, the current from ECU-IG fuse to TERMINAL 3 of the shift lock control computer.

1. SHIFT LOCK MECHANISM
With the Ignition SW ON, when a signal that Brake pedal is depressed (Stop Light SW ON) and a signal that the shift lever is put in 'P'position (Continuous Between P1 and P Of The Shift Lock Control SW) is input to the shift lock control computer, the shift lock control computer operates and current from the ECU-IG fuse flows to TERMINAL 3 of the shift lock control computer --> TERMINAL 'SLS+' --> TERMINAL 3 (4WD) of the shift lock solenoid --> TERMINAL 6 (4WD) or 1 (2WD) --> TERMINAL 'SLS-' of the shift lock control computer --> TERMINAL 7 --> GROUND. This causes the shift lock solenoid to turn ON (Plate Stopped Disengages) and the shift lever can shift into position other that "P"

2. KEY INTERLOCK MECHANISM
With the Ignition SW at ON or ACC position, when the shift lever is put in "P" position (No Continuous Between P2 And P of the Shift Lock Control SW), the current flowing from TERMINAL 6 of the shift lock control computer --> Key Interlock Solenoid is cut OFF. This causes the key Interlock solenoid to turn OFF (Lock Lever Disengages From Lock Position) and the Ignition key cab be turned from ACC to LOCK position.
