Pistons

Installation

Before installing the piston, apply a coat of

engine oil to the ring grooves and cylinder

bores.

1. If the crankshaft is already installed:

Remove the connecting rod caps and slip short

sections of rubber hose over the threaded ends

of the connecting rod bolts.

Install the ring compressor, check that the bear-

ing is securely in place, then position the piston

in the cylinder and tap it in using the wooden

handle of a hammer.

Stop tapping after the ring compressor pops

free, and check the connecting rod-to-crank jour-

nal alignment before pushing piston into place.

Install the rod caps with bearings, and torque the

nuts to 32 N-m (3.3 kgf-m, 24 Ibf-ft)

2. If the crankshaft is not installed:

Remove the rod caps and bearings, install the

ring compressor, then position the piston in the

cylinder and tap it in using the wooden handle of

a hammer.

Position all pistons at top dead center.

The arrow must face

the timing belt side

of the engine and the

connecting rod oil hole

must face the intake

manifold.

NOTE: Maintain downward force on the ring com-

pressor to prevent rings from expanding before

entering the cylinder bore.

Use the wooden handle

of a hammer to push, or

tap the piston into the

cylinder bore.

Engine Oil

Inspection

1. Check engine oil level with the engine off and the car

parked on level ground.

2. Make certain that the oil level indicated on the dip-

stick is between the upper and lower marks.

3. If the level has dropped close to the lower mark, add

oil until it reaches the upper mark.

CAUTION: Insert the dipstick carefully to avoid

bending it.ProCarManuals.com

The numbers in the middle of the API Service label tell

you the oil's SAE viscosity or weight. Select the oil for

your car according to this chart:

An oil with a viscosity of 5W - 30 is preferred for

improved fuel economy and year-round protection in the

car. You may use a 10W - 30 oil if the climate in your area

is limited to the temperature range shown on the chart.

4. Fill the engine with oil up to the specified level, run

the engine for more than three minutes, then check

for oil leakage.ProCarManuals.com

PGM-FI System

Engine Control Module (ECM)

Is the low oil pressure light on?

Try to start the engine.

Does the engine start?

Check for an open in the wire or

bulb (MIL line):

1. Turn the ignition switch OFF.

2. Connect the ECM connector ter-

minal A7 to body ground with a

jumper wire.

3. Turn the ignition switch ON (II).
NOTE: If this symptom is intermittent, check for a loose fuse No. 1 (BACK UP

LIGHTS, METER LIGHTS, 10 A) in the under-dash fuse/relay box, a poor con-

nection at ECM terminal A7, or an intermittent open in the GRN/RED wire

between the ECM (A7) and the gauge assembly.

Is the MIL on?

Substitute a known-good ECM

and recheck. If symptom/indica-

tion goes away, replace the origi-

nal
ECM.
— Repair short in the wire

between NO. 1 (BACK-UP

LIGHTS, METER LIGHTS) (10

A) fuse and gauge assembly.

— Replace No. 1 (BACK-UP

fuse.

Check for an open in the wires

(PG1, PG2 lines):

1. Turn the ignition switch ON (II).

2. Measure voltage between

body ground and ECM con-

nector terminals A12 and A25

individually.

Is there less than 1.0 V?

Repair open in the wires

between ECM (A7) and gauge

assembly.

Replace the MIL bulb.

Repair open in the wire(s)

between ECM and G101 (located

Before connecting a new fuel tube/quick-connect fitting

assembly, remove the old retainer from the mating pipe.

With the

tabs pulled

apart, pull

the retainer

3. Align the quick-connect fittings with the pipe, and

align the retainer locking pawls with the connector

grooves. Then press the quick-connect fittings onto

the pipe until both retainer pawls lock with a click-

ing sound.

NOTE: If it is hard to connect, put a small amount of

new engine oil on the pipe end.

two seconds, and fuel pressure will rise. Repeat two

or three times, and check that there is no leakage in

the fuel supply system.

Pump motor control:

The ABS control unit monitors the brake fluid pressure in the accumulator by the pressure switch ON/OFF signals. The

ABS control unit turns the pump on when the pressure in the accumulator drops, and stops the pump when the pressure

rises to the specified value.

If the pressure does not reach the specified value after the motor has operated continuously for a specified period, the

ABS control unit stops the motor and activates the ABS indicator light.

Self-diagnosis function:

The self-diagnosis function, provided in the sub-function of the ABS control unit, monitors the main system functions by

constantly transmitting the data between the two Central Processing Units (CPUs). When an abnormality is detected, the

ABS control unit turns the ABS indicator light on and stops the ABS, although the basic brake system continues to operate

normally.

When the ABS control unit detects an abnormality with the ABS and turns the ABS indicator light on, the diagnostic trou-

ble code (DTC), which shows the problem part or unit, is recorded in the control unit. The DTC can be read by the blinking

frequency of the ABS indicator light.

Fail-safe function:

When an abnormality is detected in the ABS control sys-

tem self-diagnosis, the solenoid operations are suspend-

ed by turning off the two fail-safe relays. This discon-

nects the ground circuits of all the solenoid valves to

prevent ABS operation.

Under these conditions, the braking system functions

just as an ordinary one.

Fail-safe relay:

The fail-safe relay's terminal side contact is normally

open. When there is continuity at the relay coil, the fail-

safe relay is closed, thereby connecting the ground cir-

cuit to the solenoid valve.

ABS indicator light:

REAR FAIL-SAFE RELAY

FRONT FAIL-SAFE RELAY

The ABS control unit turns the ABS indicator light on when one or more of the following abnormalities are detected. This

is only a partial list.

When the operating time of the motor in the power unit exceeds the specified period.

When vehicle running time exceeds 30 seconds without releasing the parking brake.

When absence of speed signals from any of the four wheel sensor is detected.

When the activation time of all solenoids exceeds a given time, or an open circuit is detected in the solenoid system.

When solenoid output is not detected in the simulated ABS operation when the engine is started or the vehicle is driven.

To check the indicator light bulb, the light is activated when the ignition switch is first turned on. The light goes off after

the engine is started if there is no abnormality in the system.
