Brakes

The front brake cylinder was changed to the slide pin construction used on the Camry.ABS (Anti-lock Brake System) was an option on all models without theft deterrent systems. It was basically the same inconstruction and operation as that for the '92 Camry and Celica except for the construction of the ABS actuator.A tandem type brake booster was used with the ABS option, similar to Camry and Celica.

ABS (Anti-Lock Brake System)

The ABS controlled the brake fluid pressure applied to the wheel cylinders. That prevented the wheels from locking up during a panicstop. Aside from the 2-position solenoid valve adopted in the ABS actuator, the basic construction and operation of this system are thesame as those of the '92 Camry and Celica.

The ABS actuator with four 3-position solenoid valves used in the '92 Camry and Celica was replaced by a new type actuator havingeight 2 position solenoid valves in the '93 Corolla. The new ABS actuator was composed of two functionally divided components,namely the control unit and the pressure reduction unit, as in the previous 3 position solenoid valve type actuator. These two unitshad the same function but the control unit had different solenoid valves as shown below:

The pressure holding valve controlled (opened and closed) the circuit between the brake master cylinder and the wheel cylinder. Thebrake fluid pressure from the brake master cylinder and the wheel cylinder was turned on and off accordingly.

The pressure reduction valve controlled (opened and closed) the circuit between the wheel cylinder and the reservoir. The brake fluidpressure from the wheel cylinder to the reservoir was turned on and off accordingly.

Front Suspension

A MacPherson strut type front suspension with an L-shaped lower arm as a strut bar was used, with changes to increase corneringperformance and directional stability:

The lower arm length and shape were changed along with the bushingsThe 7A-FE engine models had ball-joint type stabilizer link. It was the same in basic construction and operation as that of the'91 Corolla models with the 4A-GE engine.

21-Nov-10 1993 Toyota Corolla

corolland.com/corolla/…/1993.html 2/10

Page 3: 1993 Toyota Corolla

The cross section structure of the lower arm was changed to reduce the unsprung weight. The rear side bushing was now integratedwith the bracket, but in the previous model it used to be separate from the bracket. At the same time, the bushing shape was changedto provide more precise steering response when driving straight and during cornering, as well as to improve trace characteristics. Afront end bushing with steel inter-ring was used. Its structure was the same as in the previous model.

Rear Suspension

Dual link MacPherson strut type suspension was used at the rear as with previous models. But the following changes were made toincrease steering stability and suspension rigidity:

No. 1 and No 2 suspension arms were increased in both their span and length, as in the '92 Camry.The central diameter of the coil spring was increased, as in the '92 Camry, to increase the amount of offset of the shockabsorber.The bushing of No. 2 suspension arm had an inter-ring as in that of the '91 Corolla rarrying the 4A-GE engine.All models adopted the same front suspension used in the 7A-FE models, which were equipped with a ball-joint type stabilizerlink.

Steering

The rack and pinion steering gear was kept, but the tilt mechanism of the steering column was changed to that of the '92 Camry tofurther improve the ease of operation. The support of the steering rack housing and the rubber coupling of the intermediate shaftwere changed for better feel.

Steering Column

The rubber coupling on the intermediate shaft was changed from the press fit type to the pin type. By fastening the coupling to theNo. 1 intermediate shaft with a pin, rigidity was increased. That provided excellent steering stability and cornering response. The pintype couplings also reduces noise transmitted from the power steering system to the steering column.

Body

The body was made more rigid by increasing the rigidity of each pillar joint, optimum reinforcement of the spring support section ofthe front and rear suspension, increased use of high strength sheet steel, and refinement of the shape and construction of each part.Light weight and highly rigid high strength sheet steel was used for the engine hood, door panels and members.

Optimizing the construction of joints between panels and the location of reinforcements, utilizing continuity of underbody members,increasing the size of the member cross-section and reinforcing the suspension installation parts also increased rigidity. The sidemember panel was unified, and on doors, reinforcement was added to each joint and a side impact protection beam was used toprovide high rigidity.

Use of anti-corrosion sheet was increased and wax and scaler and PVC (Polyvinyl Chloride) coating was applied to the more rust-susceptible parts such as the edges of the door and engine hood, and the underbody to improve rust resistant performance.

Two types of anti-corrosion sheet steel were used: galvannealed steel and zinc iron alloy double layer galvannealed sheet steel.Galvannealed steel was used for many inner panels, engine compartment, etc. Zinc-iron alloy double layer galvannealed sheet steelwas used for major outer panels such as the engine hood, doors and luggage compartment door.

21-Nov-10 1993 Toyota Corolla

corolland.com/corolla/…/1993.html 4/10

Page 5: 1993 Toyota Corolla

Wax or sealer was applied to the hemmed portions of the engine hood, door panels and luggage compartment door to improve rust-resistance. The underbody was coated with PCV to a thickness of 0.5 mm (0.019in.) over the entire area and 1.0 mm (0.039 in.) atpanel joints to increase the vehicle's rust-resistance. A chip resistant coat was applied to rocker panels and front and rear wheelarches to protect them from flying stones.

The noise and vibration level was minimized by using vibration damping sheet in more areas, effective arrangement of asphalt sheets,use of a multi-layer composite structure and increased use of foamed polyurethane.

A vibration damping sheet steel consisted of an asphalt sheet sandwiched between two sheet steels in a unitary construction foreffective damping of panel vibration and noise.

In all vehicles, the passenger compartment side of the dash panel was fitted with a silencer consisting of a vinyl chloride outer surfacewith a backing of felt layers to cut out engine noise.

Resin binding asphalt sheets used under the carpet had 3-layered structure. Asphalt sheet was added to sheet steel, then a heathardened resin layer was added on top for binding. Vibration energy caused the asphalt sheet to stretch, and was thus absorbed. Theaddition of the resin layer distorted the asphalt sheet. This distortion caused even more vibration energy to be absorbed.

Aerodynamics

To improve aerodynamic performance, flush mounting was used wherever possible, and the following measures were taken:

To increase aerodynamic performance and reduce air flow resistance, each part was flush-mounted; minimizing the step and gap atthe engine hood/body and trunk lid/body areas enhanced the appearance and reduced noise and vibration.

The front door window regulator was changed from the X-arm type to the cable type to provide smoother operation and reduceweight. The rear door still had the singal arm type window regulator.

The front door glass was fitted to the carrier plate, which moves up and down the main guide. The window regulator cables woundaround the drum in the motor, with the cable ended fixed at the top and bottom of the drum. The carrier plate was attached to thecables and moved up and down in accordance with the movement of the cables.

When the power window motor or window regulator handle was rotated to the up side, the cable at the top of the drum wound in andthe cable at the lower side wound out from the drum an equal extent, causing the carrier plate to rise. When the motor or regulatorhandle was rotated to the down side, the operation was reversed and the carrier plate was lowered.

Body Electrical

Daytime running lights and an automatic light shutoff system were added; DRLs were only used in Canada.

The speedometer of this Corolla was cableless, electrical analog type, which was already in the Previa and Camry. The odometer waschanged to the pulse motor driven type. The basic construction and operation of the speedometer and odometer were the same as inthe Previa.

Air Conditioning / Heat

The Corolla had a full air mix type heater and ventilator. The air conditioning was standard equipment on LE grade model for theU.S.A. and optional on all other models for the U.S.A. and models for Canada. The adoption of a three-passage flow type condenser,larger electric fan, and drawn-cup type evaporator in the air conditioning increased its cooling efficiency. The fulcrum of the blowerswitch was moved further in. This made switch operation smoother, as less effort was required to press the lever.

and other models in the past. A 10PA15 type compressor was used, with the same basic construction and operation were the same asin the previous Corolla. The three-passage flow type condenser had three passages for the refrigerant, resulting in a greater heatexchanging capability. The condenser fan was the blower type. In combination with the radiator fan, the condenser fan speed wascontrolled in three steps (stop, low and high) according to refrigerant pressure and the engine coolant temperature. The basicconstruction and operation were the same as in the previous Corolla.

The air conditioning amplifier was mounted on top of the cooling unit. The basic functions of this amplifier were the same as in theprevious Corolla.

All functions were the same as in the previous 4A-FE engined Corolla models. When the blower switch and the A/C switch wereturned on together, the magnetic clutch relay turned on and activated the compressor. When one of the following conditions was metwhile the compressor was turned on, the magnetic clutch relay was turned off and stoped the compressor.

1. The refrigerator pressure was too low or too high and the low or high pressure switch of the dual pressure switch was turned off.2. The air temperature immediately after passage through the evaporator was detected by the thermistor to be below 30°C

(37.4°F).3. "Air conditioning cut" was requested by the ECM* (engine ECU).

When the compressor was operating or was stopped due to a request from the ECM* (engine ECU), an idle-up signal was sent to theECM (engine ECU).

Airbags

The SRS (Supplemental Restraint System) airbag, together with the seat belt, was designed to help protect the driver. In a collision,the airbag sensors detect the shock and if the front-to-rear shock was greater than a specified value, the airbag stored in the steeringwheel pad was inflated instantaneously to help reduce the shock to the driver. The airbag system was controlled by the center airbagsensor assembly. It had a self-diagnosis function. When it detected a system malfunction, it lighted up the airbag warning light on thecombination meter to alert the driver. The system components, construction and operation were the same as in the Celica. Majorfunction parts of the airbag are shown below:

Cruise control

This Corolla used the same motor type actuator as that used in the GT-S and All-Trac/4WD grades of the Celica. The basicconstruction and system operation were the same as in the Celica, but a tap-down/tap-up control was added, and diagnostic codeswere modified as shown below:

Code No. Diagnosis

11Motor on throttle open side was energized continuously.Excessive current flowed to motor drive circuit.

To read the codes, a mechanic would turn the key on, connect terminals Te and E1 of the check connector in the engine compartment,and watch the power indicator light to count the blinks.

The input signal check mode was set by operating the ignition key, control switch and main switch in the order given below:

1. Turn the ignition key to ON position2. Push the control switch to SET/COAST or RESUME/ACCEL and keep it there while turning the main switch ON. Then hold

SET/COAST or RESUME/ACCEL position 3 seconds.3. Check that the power indicator light blinks twice.
