(2) After repair, check that the ignition coil terminals
and all other ignition system lines are reconnected
securely.
(3) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.

may break the engine.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head may result in air suction and break the engine.

(j) Check that there is any fuel leak after maintenance any-
where on the fuel system.
(1) Connect a hand±held tester to the Controller Area
Network Vehicle Interface Module (CAN VIM). Then
connect the CAN VIM to the Date Link Connector 3
(DLC3).
(2) Turn the ignition switch ON and push the hand±held
tester main switch ON.
NOTICE:
Do not start the engine.
(3) Enter the following menus: DIAGNOSIS / EN-
HANCED OBDII / ACTIVE TEST / FUEL PUMP /
SPD.
(4) Please refer to the hand±held tester operator's
manual for further details.
(5) Pinch the fuel return hose.
The pressure in the high pressure line will rise to
approx. 392 kPa (4 kgf/cm
2, 57 psi). In this state,
check to see that there are no leaks from any part
of the fuel system.
NOTICE:
Always pinch the hose. Avoid bending as it may cause the
hose to crack.
(6) Turn the ignition switch OFF.
(7) Disconnect the hand±held tester and CAN VIM
from the DLC3.

ON±VEHICLE INSPECTION
CAUTION:

Check that the battery cables are connected to the
correct terminals.

Disconnect the battery cables when the battery is giv-
en a quick charge.

Do not perform tests with a high voltage insulation re-
sistance tester.

Never disconnect the battery while the engine is run-
ning.
1. CHECK BATTERY ELECTROLYTE LEVEL
Check the electrolyte quantity of each cell.
If under the lower level, replace the battery (or add distilled wa-
ter if possible) and check the charging system.
2. Except Maintenance±Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity:
1.25 to 1.29 at 20°C (68°F)
If the specific gravity is less than the specification, charge the
battery.
3. Maintenance±Free Battery:
CHECK BATTERY VOLTAGE
(a) In the case that 20 minutes have not passe4d after stop-
ping the engine, turn on the ignition switch and the electri-
cal system (headlight, blower motor, rear defogger, etc.)
for 60 seconds before removing the surface charge.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.

(c) Measure the battery voltage between the negative (±)
and positive (+) terminals of the battery.
Standard voltage:
12.5 to 12.9 V at 20°C (68°F)
If the voltage is less than the specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
4. CHECK BATTERY TERMINALS, FUSIBLE LINK AND
FUSES
(a) Check that the battery terminals are not loose or cor-
roded.
(b) Check the fusible link and fuses for continuity.
5. INSPECT DRIVE BELT
HINT:
Since the belt tensioner is used, checking the belt tension is not
necessary.
(a) Visually check the drive belt for excessive wear, frayed
cords etc.
If necessary, replace the drive belt.
HINT:

Cracks on the rib side of a drive belt are considered ac-
ceptable. If the drive belt has chunks missing from the
ribs, it should be replaced.

The drive belt tension can be released by turning the belt
tensioner counterclockwise. The pulley bolt for the belt
tensioner has a left±hand thread.
(b) Check the belt tensioner operation.

Check that the belt tensioner moves downward
when the drive belt is pressed down at the points in-
dicated in the illustration with approx. 98 N (10 kgf,
22.0 lbf) of force.

Check the alignment of the belt tensioner pulley to
make sure the drive belt does not slipped off the
pulley.
If necessary, replace the belt tensioner.
