is limited not to damage the components.)
(2) Do not apply heat directly to parts in the ECU.
3 WATER SPRINKLING METHOD:
NOTICE:
(1) Never sprinkle water directly into the engine
compartment, but indirectly change the temperature and
humidity by applying water spray onto the radiator front
surface.
(2) Never apply water directly onto the electronic
components.
4 OTHER: When a malfunction seems to occur when electrical load is excessive.When the malfunction seems to occur on a rainy day or in a
high-humidity condition. Heat the component that is the likely cause of the malfunction
with a hair dryer or similar object. Check to see if the malfunction
occurs.
Sprinkle water onto the vehicle and check to see if the malfunc-
tion occurs.
Turn on all electrical loads including the heater blower, head
lights, rear window defogger, etc. and check to see if the mal-
function occurs.ON (Service hint)

3) ABS ECU
a. Wheel Speed Control
The ECU constantly receives signals form the 4±speed sensors and a deceleration sensor (2JZ±GTE engine model),
and estimates the speed and deceleration rate of the vehicle by calculating the speed and deceleration rate of each
wheel.
b. Initial Check
An initial check is carried out every time once after the engine has started and the initial vehicle speed exceeds 6 km/h
(4 mph).
c. Self±Diagnosis
If the ABS ECU detects a malfunction in the ABS, the ABS warning light and a master warning lights in the
combination meter will light up and alert the driver that a malfunction has occurred. The ECU will also store the codes
of the malfunctions.
 SUSPENSION
1. General
The shock absorber of the 2JZ±GTE engine model with manual transmission has been changed from the
mono±tube, gas±filled shock absorber to the twin±tube, gas±filled shock absorber, which is the same type that is
used on the 2JZ±GE engine model.
The same rubber±integrated ball bushing that is used on the 2JZ±GTE engine model is used for the upper arm
bushing of the rear suspension of the 2JZ±GE engine model.
The brace rod of the rear subframe has been relocated to realize excellent riding comfort, in addition, this provides
excellent stability, an controllability.

 EXTERIOR DESIGN
1. Headlights, Turn Signal Light and Front Bumper
Multi±reflector type headlights, which contain a multiple paraboloid reflector, have been adopted for the
high±beam headlights. Accordingly, the lens cut in headlights has been significantly decreased to improve the
appearance.
The shape of the turn signal light lenses has been matched to the curvature of the bumper in order to make them
appear integrated with the bumper. In addition, clear lenses are used, and the parking lights gave been changed from
those enclosed in the headlights to those enclosed in the turn signal lights.
A bar has been added to the air intake opening in the center of the front bumper.
2. Rear Combination Light
The lens cut of the rear combination lights has been changed from the vertical cut to the lateral cut. In addition, the
rear combination lights have adopted multi±reflectors. As a result of these changes a light design has been achieved
to give a sensor for translucency and depth.
