Current is applied at all times through the POWER fuse to TERMINAL 5 of the power relay. With the ignition SW turned on,
the current flows through the GAUGE fuse to TERMINAL 7 of the integration relay to TERMINAL (A) 12 (w/o theft deterrent
system), (B) 3 (w/ theft deterrent system) to TERMINAL 1 of the power relay to TERMINAL 2 to GROUND, as a result, power
relay is activated and the current to TERMINAL 5 of the power relay flows from TERMINAL 3 of the power relay to
TERMINAL 4 of the moon roof control relay.
1. SLIDE OPEN OPERATION
Only when the slide open switch is valid and actuated the moon roof motor continually will operate towards the open
direction of the roof panel.
Releasing and again depressing the open switch, or depressing another operation switch shall cancel this express open
function. The relay shall only operate the moon roof motor continually for approx. 20 seconds per actuation.
2. SLIDE CLOSE OPERATION
Only when the tilt up switch is valid and actuated the moon roof motor will operate towards the close direction of the roof
panel.
When the moon roof reaches about 120 mm short of the fully closed position, the limit switch No.2 is turned from on to off.
Thereby signaling the moon roof control relay to stop the motor. The motor can not continue to operate until the close switch
is released and again depressed.
3. TILT UP OPERATION
Only when the tilt up switch is valid and actuated the moon roof motor will operate towards the closed direction of the roof
panel.
4. TILT DOWN OPERATION
Only when the slide open switch is valid and actuated the moon roof motor will operate towards the open direction of the roof
panel.
5. KEY OFF MOON ROOF OPERATION
With the ignition SW turned from on to off, the integration relay operates and current flows from the DOOR fuse to
TERMINAL (A) 13 (w/o theft deterrent system), (B) 1 (w/ theft deterrent system) of the relay to TERMINAL (A) 12 (w/o theft
deterrent system), (B) 3 (w/ theft deterrent system) to TERMINAL 1 of the power relay to TERMINAL 2 to GROUND for about
43 seconds. In the same way as normal operation, the current flows from the POWER fuse to TERMINAL 5 of the power
relay to TERMINAL 3 to TERMINAL 4 of the moon roof control relay. As a result, for about 43 seconds after the ignition SW
is turned off, the functioning of this relay makes it possible to open and close the moon roof. Also, by opening the front door
(Door courtesy SW on) within about 43 seconds after turning the ignition SW to off, a signal is input to TERMINALS 6 or (A) 8
(w/o theft deterrent system), (B) 6 (w/ theft deterrent system) of the integration relay. As a result, the relay turns off and open
close movement of the moon roof stops.

ABS AND TRACTION CONTROL
(ABS)
ABS is a brake system designed for the purpose to improve the operating ability securing the stability of the vehicle by
preventing the looking±up of the vehicle controlling the wheel cylinder pressure of all the four wheels at the time of sudden
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 and traction ECU.
(2) Stop light SW signal
A signal is input to TERMINAL STP of the ABS and traction ECU when brake pedal is depressed.
2. SYSTEM OPERATION
When the wheels are to be locked±up, the solenoid inside the actuator will be controlled by the signal from the ABS and
traction ECU and the brake fluid in the wheel cylinder will flow through the reservoir and reduce the hydraulic pressure.
While the ABS is in operation, as the ABS and traction ECU always outputs the operation signal to the pump inside the
actuator, brake fluid stored inside the reservoir will be suctioned up by the pump inside the actuator and returned to the
master cylinder.
When the hydraulic pressure of the wheel cylinder is decompressed or increased until the necessary hydraulic pressure, the
solenoid inside the actuator is controlled by the control signal from the ABS and traction ECU and as a result, hydraulic
pressure of the wheel cylinder will be closed at both routes of the master cylinder and reservoir sides and the hydraulic
pressure of the wheel cylinder will become to be in the holding condition.
If the increase of hydraulic pressure volume of the wheel cylinder becomes necessary, with the control signal from the ABS
and traction ECU, the solenoid inside the actuator will be controlled and become the same condition as usual and the brake
fluid of the master cylinder will be sent to the wheel cylinder and will increase the hydraulic pressure of the wheel cylinder. At
this time, in the case that the brake fluid stays left in the reservoir, it will be sucked up by the pump inside the actuator and
will be sent to the wheel cylinder.
Also, increasing speed of the hydraulic pressure is controlled by outputting the increasing and the said holding one after
another.
(Traction control)
Traction control system is designed to perform the engine output control by the fuel cut and hydraulic pressure control of
driving wheel brake and control the spinning of the driving wheels. By doing this, it improves starting acceleration and
operating ability of the vehicle securing the driving ability in accordance with the road surface condition.
3. TRACTION CONTROL OPERATION
Estimating the vehicle speed from the rear wheel speed, comparing it with the front, driving wheel speed and judging the grip
condition of the driving wheels. From the estimated vehicle speed, target speed of the driving speed will be set. When the
front, driving wheel speed exceeds the control starting speed, it judges that the tire slip is occurred and performs the fuel cut
cylinder number control and brake control and then adjust to make the front wheel speed become the traction control target
speed. Controlling of the traction control will be completed when the vehicle move onto the road where the driving wheels will
not have a tire slip or when the driver decelerate.
