1999 TOYOTA CAMRY light

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.

Current always flows to TERMINAL 1 of the integration relay through the DOME fuse.
1. SEAT BELT WARNING SYSTEM
When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 7 of the integration relay. At the same
time, current flows to TERMINAL 9 of the relay from the GAUGE fuse through the seat belt warning light. This current
activates the relay and the current flowing through the warning light flows from TERMINAL 9 of the relay to TERMINAL 10 to
GROUND, causing the warning light to light up. A buckle SW off signal is input to TERMINAL 8 of the relay to TERMINAL 10
to GROUND, causing the warning light to light up. A buckle SW off signal is input to TERMINAL 8 of the relay, the current
flowing to TERMINAL 1 of the relay flows from TERMINAL 10 to GROUND and the seat belt warning buzzer sounds for
approx. 6 seconds. However, if the seat belt is put on during this period (While the buzzer is sounding), signal input to
TERMINAL 8 of the relay stops and the current flow from TERMINAL 1 of the relay to TERMINAL 10 to GROUND is cut,
causing the buzzer to stop.
2. KEY REMINDER SYSTEM
With the ignition key inserted in the key cylinder (Unlock warning SW on), the ignition SW still off and driver's door open
(Door courtesy SW on), when a signal is input to TERMINAL 6 of the integration relay, the relay operates, current flows from
TERMINAL 1 of the relay to TERMINAL 10 to GROUND and key reminder buzzer sounds.
