exception of the new Celica.
MR2 and Van are not contained in this manual because 1990 models of these vehicles will not be produced.
For new features of the Celica and for detailed service specifications and repair procedures of each 1990 model year
vehicle, refer to the following manuals:

DESCRIPTION
The following changes are made simultaneously in some models for the 1990 model year.
(1) : Door–mounted automatic belts with manual lap belts are made standard equipment for front seat belts for the U.S.
(2) : For Canada, a daytime running light system, which lights the headlights and taillights during daylight hours, is used
to improve vehicle visibility from the outside during the daytime.
(3) : In vehicles which were previously equipped with the electronically controlled door lock control system, in which
all the doors were unlocked by operating the key in the lock of the driver ’s door, the system is changed to the
2–operation type system used in the Cressida. In this system, operating the driver’s door lock one time unlocks only
the driver ’s door, while operating the driver ’s door lock twice in succession unlocks the other doors.
Models in which the above changes have been made are shown in the following table.

FRONT SEAT BELT
Door mounted automatic belts with manual lap belt are standard equipment in all Tercel and Corolla models for the U.S.
The shoulder belts are two–point ELR (Emergency Locking Retractor) belts. The shoulder belt retractors are mounted
in the bottom of the rear console box. The shoulder belt anchorages are mounted on the door frames and the shoulder
belts can be connected or disconnected using the buckles. A bracket is provided in each of the center pillars which assures
the rigidity of the shoulder belt anchorages.
The manual lap belts are two–point ALR (Automatic Locking Retractor) belts. The belt retractors are located at the bottom
of the center pillars in the rocker inner panel. The lap belt buckles slide fore and aft with the seats.

DAYTIME RUNNING LIGHT SYSTEM (Only for Canada)
GENERAL
The daytime running light system, in which the headlights and taillights are turned on automatically when the engine
is started, is standard in all models for Canada. However, in the Toyota Supra, the front fog lights light up instead
of the headlights and in the Corolla 2–door coupe, exclusive daytime lights light up.

FUNCTION
The daytime running light system operates when the ignition switch is turned to the ON position and the engine is
started, with the operation of each switch turning the lights on and off as shown in the table below. (The lights do not
go on when the ignition switch is in the ON position only. The lights also stay on in the event that the engine stalls
after the engine is started.)

When the ignition switch is turned off, input and output signals at gates are in the condition shown on the next
page.
If the ignition switch is turned on in this condition, the voltage at terminal (4) goes high and the input to AND
gate A changes from “0” to “1”.
The electric current passing the charge light is grounded via the alternator and the voltage at terminal (22) is held
low. Therefore, the output from the AND gate A remains unchanged and the system remains inoperative.
If engine stalls after starting, lights stay on until ignition key is turned off.

2. After Engine Starting
When the engine is started, the alternator begins charging and the voltage at terminal (22) goes high and the input
to AND gate A changes from “0” to “1”. Therefore, the output also changes from “0” to “1”.
When the “1” signal from AND gate A continues for 0.5 seconds or longer, the delay and memory circuit judges
that the engine has started and sends “1” to AND gate B.
Since the output from AND gate B changes from “0” to “1”, the output from OR gates A and B also changes from
“0” to “1” and causes Tr1 and Tr2 to go on respectively. Therefore, the taillight relay and fog light relay are turned
on and the daytime running lights are turned on as a result.

3. Headlight (Low Beam) Turned ON
When the light control switch is put in the head position and the dimmer switch is put in low position while the
daytime running lights are turned on, the input to NAND gate A from light control switch terminals T and H
changes from “1” to “0”.
At the same time, the input signal to IC (Integrated Circuit) changes from “1” to “0”, so the IC then turns Tr
As a result, the headlight relay is turned on and the headlights (low beam) are turned on.

on.
When the input to NAND gate A changes to “0”, output changes from “1” to “0” and the output of AND gate B
also changes from “1” to “0”.
Since the output from OR gate B changes from “1” to “0” and causes Tr
and the fog lights (daytime running lights) go off automatically.
to go off, the fog light relay goes off

The “0” signal from AND gate B is also supplied to OR gate A. Since the “0” signal from the light control switch
(terminal T) is supplied to the other terminal, OR gate A maintains the output “1” and the taillights remain on
as a result.
NOTE: Fog lights can be turned on by turning the fog light switch on in this condition.

DOOR LOCK CONTROL SYSTEM
The method of unlocking all the doors when the driver’s door lock is operated by the key in models with the electronically
controlled door lock control system is changed. Previously, one operation of the driver’s door lock with the key unlocked
all the doors together with the driver’s door, but this has been changed to the method used in the current Cressida, in which
the only driver’s door is unlocked mechanically when the driver’s door lock is operated once. Operating driver’s door lock
twice in succession unlocks the other doors electronically. Operating the door lock on the passenger side once unlocks
all the doors as before. This change is made through changes in the operation of the door lock control relay.
