ON-VEHICLE INPECTION
a.Check that the battery cables are connected to the correct terminals.
b. Disconnect the battery cables when the battery is given a quick charge.
c. Never disconnect the battery while the engine is running.
CHECK BATTERY VOLTAGE
1.If 20 minutes have not passed since the engine was stopped, turn the ignition switch ON and turn on the electrical
system (headlamp, blower motor, rear defogger etc.) for 60 seconds to remove the surface charge.
2. Turn the ignition switch OFF and turn off the electrical systems.
3. Measure the battery voltage between the negative ( - ) and positive (+) terminals of the battery.
Standard voltage : 12.5 ~ 12.9V at 20°C(68°F)
If the voltage is less than specification, charge the battery.
CHECK THE BATTERY TERMINALS AND FUSES
1.Check that the battery terminals are not loose or corroded.
2. Check the fuses for continuity.
INSPECT DRIVE BELT
Visually check the belt for excessive wear, frayed cords etc.
If any defect has been found, replace the drive belt.
Cracks on the rib side of a belt are considered acceptable. If the belt has chunks missing from the ribs, it should
be replaced.
VISUALLY CHECK ALTERNATOR WIRING AND LISTEN FOR ABNORMAL NOISES
1.Check that the wiring is in good condition.
2. Check that there is no abnormal noise from the alternator while the engine is running.
CHECK DISCHARGE WARNING LIGHT CIRCUIT
1.Warm up the engine and then turn it off.
2. Turn off all accessories.
3. Turn the ignition switch "ON". Check that the discharge warning light is lit.
4. Start the engine. Check that the light is lit.
If the light does not go off as specified, troubleshoot the discharge light circuit.
INSPECT CHARGING SYSTEM
VOLTAGE DROP TEST OF ALTERNATOR OUTPUT WIRE
This test determines whether or not the wiring between the alternator "B" terminal and the battery (+) terminal is good
by the voltage drop method.
PREPARATION

TEST
1.Check to see that the voltmeter reads as the same value as the battery voltage. If the voltmeter reads 0V, and the
open circuit in the wire between alternator "B" terminal and battery ( - ) terminal or poor grounding is suspected.
2. Start the engine and turn on the headlamps.
3. Set the headlamps to high beam and the heater blower switch to HIGH, quickly increase the engine speed to 2,500
rpm and read the maximum output current value indicated by the ammeter.
After the engine start up, the charging current quickly drops.
Therefore, the above operation must be done quickly to read the maximum current value correctly.
RESULT
1.The ammeter reading must be higher than the limit value. If it is lower but the alternator output wire is in good
condition, remove the alternator from the vehicle and test it.
Limit value : 70Ë of the rated current
a.The nominal output current value is shown on the nameplate affixed to the alternator body.
b. The output current value changes with the electrical load and the temperature of the alternator itself.
Therefore, the nominal output current may not be obtained. If such is the case, keep the headlamps on the
cause discharge of the battery, or use the lights of another vehicle to increase the electrical load.
The nominal output current may not be obtained if the temperature of the alternator itself or ambient
temperature is too high.
In such a case, reduce the temperature before testing again.
2. Upon completion of the output current test, lower the engine speed to idle and turn off the ignition switch.
3. Disconnect the battery ground cable.
4. Remove the ammeter and voltmeter and the engine tachometer.
5. Connect the alternator output wire to the alternator "B" terminal.
6. Connect the battery ground cable.
REGULATED VOLTAGE TEST
The purpose of this test is to check that the electronic voltage regulator controls voltage correctly.
PREPARATION
1.Prior to the test, check the following items and correct if necessary.
Check that the battery installed on the vehicle is fully charged. The battery checking method is described in the
section "Battery".
Check the alternator drive belt tension. The belt tension check method is described in the section "Inspect drive
belt".
2. Turn ignition switch to "OFF".
3. Disconnect the battery ground cable.
4. Connect a digital voltmeter between the "B" terminal of the alternator and ground. Connect the (+) lead of the
voltmeter to the "B" terminal of the alternator. Connect the ( - ) lead to good ground or the battery ( - ) terminal.
5. Disconnect the alternator output wire from the alternator "B" terminal.

6.Connect a DC ammeter (0 to 150A) in series between the "B" terminal and the disconnected output wire.
Connect the ( - ) lead wire of the ammeter to the disconnected output wire.
7. Attach the engine tachometer and connect the battery ground cable.
TEST
1.Turn on the ignition switch and check to see that the voltmeter indicates the following value.
Voltage: Battery voltage
If it reads 0V, there is an open circuit in the wire between the alternator "B" terminal and the battery and the battery
( - ) terminal.
2. Start the engine. Keep all lights and accessories off.
3. Run the engine at a speed of about 2,500 rpm and read the voltmeter when the alternator output current drops to
10A or less
RESULT
1.If the voltmeter reading agrees with the value listed in the regulating voltage table below, the voltage regulator is
functioning correctly. If the reading is other than the standard value, the voltage regulator or the alternator is faulty.

CONNECTOR INSPECTION PROCEDURE

Faults with the following items will illuminate the MILa. Heated oxygen sensor (HO2S)
b. Mass Air Flow sensor (MAFS)
c. Throttle position sensor (TPS)
d. Engine coolant temperature sensor (ECTS)
e. Idle speed control actuator (ISCA)
f. Injectors
g. ECM
Refer to "INSPECTION CHART FOR DIAGNOSTIC TROUBLE CODES (DTC)" for more information.
1. After turning ON the ignition key, ensure that the light illuminates for about 5 seconds and then goes out.
2. If the light does not illuminate, check for an open circuit in the harness, a blown fuse or a blown bulb.
Self-Diagnosis
If a sensor connector is disconnected with the ignition switch turned on, the diagnostic trouble code (DTC) is
recorded. In this case, disconnect the battery negative terminal ( - ) for 15 seconds or more, and the diagnosis
memory will be erased.
THE RELATION BETWEEN DTC AND DRIVING PATTERN IN EOBD SYSTEM
1.When the same malfunction is detected and maintained during two sequential driving cycles, the MIL will
automatically illuminate.
2. The MIL will go off automatically if no fault is detected after 3 sequential driving cycles.
3. A Diagnostic Trouble Code(DTC) is recorded in ECM memory when a malfunction is detected after two sequential
driving cycles. The MIL will illuminate when the malfunction is detected on the second driving cycle.
If a misfire is detected, a DTC will be recorded, and the MIL will illuminate, immediately after a fault is first
detected.

2) L&R brake is released in 1st gear when the vehicle speed is more than 5KPH approximately.
Torque converter and shaft
The torque converter consists of an impeller(pump), turbine and stator assembly in a single unit. The pump is
connected to the engine crankshaft and turns as the engine turns. This drawing force is transmitted to the turbine
through the oil which is recycled by the stator.
The transmission has two parallel shafts ; the input shaft and the output shaft. Both shafts are in line with the engine
crankshaft. The input shaft includes the overdrive clutch, reverse clutch, underdrive clutch, one way clutch, 2ND brake,
low&reverse brake, overdrive planetary carrier, output planetary carrier and transfer drive gear. The output shaft
includes the transfer driven gear.
CLUTCHES
The gear changing mechanism utilizes three multi- disc clutches. The retainers of these clutches are fabricated from
high- precision sheet metal for lightness and ease of production. Also, more responsive gearshifts at high engine
speeds are achieved by a pressure- balanced piston mechanism that cancels out centrifugal hydraulic pressure. This
mechanism replaces the conventional ball check valve.
UNDERDRIVE CLUTCH
The underdrive clutch operates in 1st, 2nd, and 3rd gears and transmits driving force from the input shaft to the
underdrive sun gear(A).
The components comprising the under clutch are as illustrated below.

SERVICE ADJUSTMENT PROCEDURE
Automatic transaxle fluid
INSPECTION 1. Drive the vehicle until the fluid reaches normal operating temperature [70~80°C].
2. Place the vehicle on a level surface.
3. Move the selector lever through all gear positions. This will fill the torque converter and the hudraulic system with
fluid and move the selector lever to the "N" (Neutral) or "P"(Park) position.
4. Before removing the oil level gauge, wipe all contaminants from around the oil level gauge. Then take out the oil
level gauge and check the condition of the fluid.
If the fluid smells as if it is burning, it means that the fluid has been contaminated by fine particles from the
bushes and friction materials, a transaxle overhaul may be necessary.
5. Check that the fluid level is at the HOT mark on the oil level gauge. If the fluid level is low, add automatic transaxle
fluid until the level reaches the "HOT" mark.
Auto transaxle fluid:
DIAMOND ATF SP - III, SK ATF SP - III
Quantity : 8.5ℓ (9.0 US qt, 7.5 lmp.qt)
Low fluid level can cause a variety of a abnormal conditions because it allows the pump to take in air along
with fluid. Air trapped in the hydraulic system forms bubbles, which are compressable. Therefore, pressures
will be erratic, causing delayed shifting ,slipping clutches and brakes, etc. Improper filling can also raise fluid
level too high. When the transaxle has too much fluid, gears churn up foam and acuise the same conditions
which occur with low fluid level, resulting in accelerated deterioration of automatic transaxle fluid. In either
case, air bubbles can cause overheating, and fluid oxidation, which can interfere with normal valve, clutch, and
brake operation. Foaming can also result in fluid escaping from the transaxle vent where it may be mistaken
for a leak.
6. Insert the oil level gauge(A) securely.
When new, automatic transmission fluid should be red. The red dye is added so the assembly plant can
identify it as transmission fluid and distinguish it from engine oil or antifreeze. The red dye, which is not an
indicator of fluid quality, is not permanent. As the vehicle is driven the transmission fluid will begin to look
darker. The color may eventually appear light brown.
