DOOR LOCK CONTROL
Current always flows to TERMINAL (A) 13 of the integration relay through the DOOR fuse.
When the ignition SW is turned on, the current flowing through the GAUGE Fuse flows to TERMINAL 7 of the integration
relay to TERMINAL (A) 12 to the POWER relay (Coil side) to GROUND.
1. MANUAL LOCK OPERATION
When the door lock control SW or door key lock and unlock SW are operated to LOCK position, a lock signal is input to
TERMINAL (A) 1 or (A) 3 of the integration relay and causes the relay to function. Current flows from TERMINAL (A) 13 of
the relay to TERMINAL (A) 6 to TERMINAL 2 of the door lock motors to TERMINAL 3 to TERMINAL (A) 7 of the relay to
TERMINAL 10 to GROUND and the door lock motor causes the door to lock.
2. MANUAL UNLOCK OPERATION
When the door lock control SW or door key lock and unlock SW are operated to UNLOCK position, an unlock signal is input
to TERMINAL (A) 2, (A) 4 or (A) 5 of the integration relay and causes the relay to function. Current flows from TERMINAL (A)
13 of the relay to TERMINAL (A) 7 to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL (A) 6 of the relay
to TERMINAL 10 to GROUND and door lock motors causes door to unlock.
3. DOUBLE OPERATION UNLOCK OPERATION
When the door key lock and unlock SW front LH is turned to the unlock side, only the driver's door to unlock. Turning the
door key lock and unlock SW front LH to the unlock side causes a signal to be input to TERMINAL (A) 4 of the relay, and if
the signal is input again within 3 seconds by turning the SW to the unlock side again, current flows from TERMINAL (A) 7 of
the integration relay to TERMINAL 3 of the door lock motors to TERMINAL 2 of the door lock motors to TERMINAL (A) 6 of
the relay to TERMINAL 10 to GROUND, causing the door lock motors to operate and unlock the doors.
4. IGNITION KEY REMINDER OPERATION
When the door is locked using the door lock knob with the ignition key remaining in the key cylinder and door opened, it is
automatically unlocked. Additionally, if lock operation is made by the door lock control SW or door key lock and unlock, after
the lock operation is completed, the doors are unlocked automatically.

ABS
This system controls the respective brake fluid pressures acting on the disc brake cylinders of the right front wheel, left front
wheel and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock. This results in improved
directional stability and steerability during panic braking.
1. INPUT SIGNALS
(1) Speed sensor signal
The speed of the wheels is detected and input to TERMINALS FL+, FR+, RL+ and RR+ of the ABS ECU.
(2) Stop light SW signal
A signal is input to TERMINAL STP of the ABS ECU when the brake pedal is depressed.
2. SYSTEM OPERATION
During sudden braking the ABS ECU has signals input from each sensor, which controls the current to the solenoid inside
the actuator and lets the hydraulic pressure acting on each wheel cylinder escape to the reservoir. The pump inside the
actuator is also operating at this time and it returns the brake fluid from the reservoir to the master cylinder, thus preventing
locking of the vehicle wheels.
If the ABS ECU judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current on the solenoid is
controlled and the hydraulic pressure is increased. Holding of the hydraulic pressure is also controlled by the ABS ECU, by
the same method as above. Pressure reduction, holding and increase are repeated to maintain vehicle stability and to
improve steerability during sudden braking.
