Shift Interlock: Description and Operation
SYSTEM OUTLINEWhen the ignition SW is at ACC position, the current flows from ACC fuse to shift look ECU TERMINAL ACC, and at ON position, the current flows from ECU IG fuse to shift lock ECU TERMINAL 5.
1. SHIFT LOCK MECHANISM
When the signal that the brake pedal is depressed (Stop light SW ON) and the shift lever is placed in P position is input into the shift lock ECU, the current flows from TERMINAL E to GROUND. As a result, the shift lock solenoid is turned on (Plate stopper is released) and the shift lever can be placed in a position other than P position.
2. KEY INTERLOCK MECHANISM
When the shift lever is placed to P position with the ignition SW ON or at ACC position, the current from shift lock ECU to key interlock solenoid is cut off. As a result, the key interlock solenoid is turned off
The lock lever is released from lock position) and the ignition key can be placed to LOCK position from ACC.
