1997 TOYOTA SUPRA headlights

25 SUPRAÐ NEW FEATURES
NEW FEATURES
 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.

4. CHECK OF THE THEFT DETERRENT SYSTEM OPERATION.
HINT:
Check if the theft deterrent indicator light is blinking.
When any of the following operations (a) or (b) is done, the system sounds the horns as theft deterrent horn
and flashes the headlights and taillights for about one minute to alert. At the same time, the system discon-
nects the starter motor circuit and locks all doors (if all doors are not locked, the system repeats door locking
operation every 2 seconds during the one minute alert time).
(a) Open the engine hood using the engine hood opener lever.
(b) Unlock any of the front or rear doors without key operation.
5. CANCELING OF THE THEFT DETERRENT SYSTEM IN OPERATING CONDITION.
The theft deterrent operation can be cancelled when any of the following conditions is met:
No.ConditionCancelling Operation
1Unlock left or right door with the key.
2Unlock doors with wireless door lock control system.
3Insert key into ignition key cylinder and turn it to the ACC or ON position.*2
4About 1 minute passes after theft deterrent operation begins.Automatic stop*1
*1: In this case, the theft deterrent system resets in about 2 seconds if all doors are closed.
*
2: The alarm will be off, but the engine will not operate. To restart the engine, see No.1
6. ECU TERMINAL VALUES MEASUREMENT USING
TOYOTA BRAKE-OUT-BOX AND TOYOTA HAND-
HElD TESTER
(a) Hook up the TOYOTA brake- out- box and TOYOTA
hand-held tester to the vehicle.
(b) Read the ECU input/output values by following the
prompts on the hand-held tester screen.
HINT:
TOYOTA hand-held tester has a ºSnapshotº function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems.
Please refer to the TOYOTA hand-held tester/TOYOTA break-
out-box operator's manual for further details.

Headlight Control Relay Circuit
CIRCUIT DESCRIPTION
When the theft deterrent system is activated, it causes the Tr in the ECU to switch on and off at approximately
0.2 sec. intervals. This switches the headlight control relay on and off, thus flashing the headlights (See the
wiring diagram below).
In this condition, if any of the following operations is done, the Tr in the ECU goes off and the headlight control
relay switches off, thus stopping the headlights flashing:
(1) The front LH or RH door is unlocked with a key.
(2) The ignition switch is turned to the ACC or ON position.
(3) Approximately 1 minute elapses.
