Do not depress accelerator pedal when starting.

Immediately after starting, do not rev up engine unneces-
sarily.

Do not rev up engine just prior to shutdown.

When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.
–Keep the antenna as far as possible from the electronic
control units.
–Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
–Adjust the antenna and feeder line so that the standing-
wave radio can be kept smaller.
–Be sure to ground the radio to vehicle body.

ENGINE ASSEMBLY

REMOVAL
Outline
Remove engine and transaxle assembly with front suspension member from vehicle downward. Separate
front suspension member, and then separate engine and transaxle.
Preparation
1. Release fuel pressure. Refer to EC-49, "FUEL PRESSURE RELEASE" .
2. Drain engine coolant from radiator. Refer to CO-10, "
Changing Engine Coolant" .
CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belt.
3. Remove the following parts.

Hood assembly; Refer to BL-13, "HOOD" .

Undercover and splash guards (RH and LH)

Front road wheels and tires

Battery, battery tray and battery tray bracket; Refer to SC-4, "BATTERY" .

Drive belt; Refer to EM-14, "DRIVE BELTS" .

Air duct (inlet); Refer to EM-17, "AIR CLEANER AND AIR DUCT" .

Air cleaner case (upper) with mass air flow sensor and air duct assembly; Refer to EM-17, "AIR
CLEANER AND AIR DUCT" .

Alternator and alternator bracket; Refer to SC-27, "CHARGING SYSTEM" .

Radiator and radiator cooling fan assembly, reservoir tank of radiator and system hoses; Refer to CO-
13, "RADIATOR" .
4. Disconnect engine room harness connector from ECM side and set it aside for easier work.
5. Disconnect all vacuum hoses and air hoses connected to vehicle side at engine side.
Engine Room LH
1. Disconnect heater hose, and install plug it to prevent engine coolant from draining. Refer to CO-24,
"THERMOSTAT AND WATER CONTROL VALVE" .
2. Disconnect fuel feed hose, and plug it to prevent fuel from draining. Refer to EM-34, "
FUEL INJECTOR
AND FUEL TUBE" .
3. Disconnect control cable from transaxle. Refer to AT- 2 1 3 , "
SHIFT CONTROL SYSTEM" .
4. Disconnect B terminal harness of starter motor. Refer to SC-14, "
STARTING SYSTEM" .
Engine Room RH
1. Remove IPDM E/R and bracket. Refer to PG-17, "IPDM E/R (INTELLIGENT POWER DISTRIBUTION
MODULE ENGINE ROOM)" .
2. Remove A/C compressor with piping connected from engine. Temporarily secure it on vehicle side with a
rope to avoid putting load on it. Refer to ATC-134, "
Removal and Installation of Compressor" .
3. Remove reservoir tank of power steering oil pump. Temporarily secure it on engine side with a rope. Refer
to PS-39, "
HYDRAULIC LINE" .
Vehicle Underbody
1. Remove RH and LH front drive shafts. Refer to FAX-8, "FRONT DRIVE SHAFT" .
2. Remove exhaust front tube. Refer to EX-2, "
EXHAUST SYSTEM" .
3. Remove rear plate cover from oil pan (upper). Then remove bolts fixing drive plate to torque converter.
Refer to EM-26, "
OIL PAN AND OIL STRAINER" and AT- 2 4 1 , "TRANSAXLE ASSEMBLY" .
4. Remove transaxle joint bolts which pierce at oil pan (upper) lower rear side. Refer to AT- 2 4 1 , "
TRAN-
SAXLE ASSEMBLY" .
5. Disconnect connecting rod for front stabilizer. Refer to FSU-5, "
FRONT SUSPENSION ASSEMBLY" .
6. Remove steering lower joint from steering gear. Refer to PS-12, "
STEERING COLUMN" .
7. Remove power steering fluid piping from front suspension member. Refer to PS-39, "
HYDRAULIC LINE"
.
8. Disconnect power steering fluid piping at a point between vehicle and engine, and install plug it to prevent
power steering fluid. Refer to PS-39, "
HYDRAULIC LINE" .

Control Unit Circuit Test
System Description:When the switch is ON, the control unit lights up the lamp.
INPUT-OUTPUT VOLTAGE CHART
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. Control unit
does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to light up the
lamp.
INPUT-OUTPUT VOLTAGE CHART
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0V. Control unit does
not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not control ground to light up the lamp.
Control Units and Electrical PartsBAS0007J
PRECAUTIONS

Never reverse polarity of battery terminals.

Install only parts specified for a vehicle.

Before replacing the control unit, check the input and output and functions of the component parts.

Do not apply excessive force when disconnecting a connector.
