Shift Lock Mechanism; Key Interlock Mechanism; Shift Lock Ecu; Stop Light Sw - Toyota Camry 1999 Electrical Troubleshooting Manual

SYSTEM OUTLINE
When the ignition SW is turned to ACC position the current from the CIG fuse flows to TERMINAL 1 of the shift lock ECU, in
the ON position, the current from the ECU–IG fuse flows to TERMINAL 3 of the ECU.

1. SHIFT LOCK MECHANISM

With the ignition SW on, when a signal that the brake pedal is depressed (Stop light SW on) and a signal that the shift lever
is put in P position (Continuity between P1 and P of the shift lock control SW) is input to the shift lock ECU, the ECU
operates and current flows from TERMINAL 3 of the ECU to TERMINAL SLS+ of the shift lock solenoid to solenoid to
TERMINAL SLS– to TERMINAL 5 of the ECU to GROUND. This causes the shift lock solenoid to turn on (Plate stopper
disengages) and the shift lever can shift into position other than the P.

2. KEY INTERLOCK MECHANISM

With the ignition SW ON or ACC position, when the shift lever is put in P position (No continuity between P2 and P of shift
lock control SW), the current flowing from TERMINAL 4 of the shift lock ECU to the 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 can be turned
from ACC to LOCK position.
