4. 5S-FE Engine
The intake system from the inlet duct to the throttle body has been improved to increase torque and reduce
noise.
The direction of the rotation of the radiator cooling fan has been reversed.
A 2-way exhaust control system has been adopted on the TMMK made model.
Along with the discontinuance of the air assist system, the fuel injectors and the IAC valve have been
changed for the California specification model, in order to meet ULEV (Ultra-Low Emission Vehicle) re-
quirement.
The system for detecting evaporative emission leaks has been changed. For details, see the General 2000
Features section.
5. 5S-FNE Engine
Based on the 5S-FE gasoline engine, the 5S-FNE engine uses compressed natural gas. The fuel lines have
been designed exclusively for compressed natural gas application.
6. 1MZ-FE Engine
The system for detecting evaporative emission leaks has been changed. For details, see the General 2000
Features section.
A diagnostic trouble code (DTC) has been added for indicating a thermostat malfunction.
7. Automatic Transaxle
The overdrive switch has been changed to the momentary type. For details, see the General 2000 Features
section.
The differential gear ratio of the A140E automatic transaxle has been changed for the 5S-FNE engine mod-
el to accommodate the performance of the 5S-FNE engine.

SCHEDULED MAINTENANCE LOGS19 Towing a Trailer or Using a Camper
or Car-Top Carrier
•Inspect brake linings/drums and brake pads/discs
•Inspect nuts and bolts on chassis and body
•Replace differential oil
•Replace transmission fluid or oil
•Replace transfer oil *
•Lubricate propeller shaft and re- torque bolts*
Off-Road Maintenance
If you own a Land Cruiser or a four- wheel drive RAV4,
Tacoma or 4Runner, you should check the following items
daily whenever you drive off- road through deep sand, mud
or water:
•Brake lines and hoses
•Brake linings/drums and brake pads/discs
•Engine air filter
•Differential oil
•Steering linkage
•Transfer oil
•Transmission fluid or oil
•Wheel bearings
For all four- wheel drive vehicles except RAV4, you should
also lubricate the propeller shafts daily.
Determining Your Vehicle’s Maintenance Needs

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.
