SERVICING THE ELECTRICAL SYSTEM
Before replacing a component related to the electrical system
and before undertaking any repair procedures involving the
electrical system, be sure to first disconnect the negative
( - ) cable from the battery in order to avoid damage caused
by short-circuiting.
Caution
Before connecting or disconnecting the negative ( - ) cable,
be sure to turn off the ignition switch and the lighting
switch.
(If this is not done, there is the possibility of
semiconductor parts being damaged.)
APPLICATION OF ANTI-CORROSION AGENTS
AND UNDERCOATS
If oil or grease gets onto the oxygen sensor, it will cause
a drop in the performance of the sensor.
Cover the oxygen sensor with a protective cover when applying
anti-corrosion agents and undercoats.
PRE-INSPECTION CONDITION
“Pre-inspection condition” refers to the condition that the
vehicle must be in before proper engine inspection can be
carried out. If you see the words “Set the vehicle to the
pre-inspection condition”. in this manual, it means to set the
vehicle to the following condition.
DEngine coolant temperature: 80 to 90_C
DLamps, electric cooling fan and all accessories: OFF
DM/T: Neutral
DA/T: P range
VEHICLE WASHING
If high-pressure car-washing equipment or steam car-washing
equipment is used to wash the vehicle, be sure to note the
following information in order to avoid damage to plastic
components, etc.
DSpray nozzle distance: Approx. 40 cm or more
DSpray pressure: 3,900 kPa or less
DSpray temperature: 82_C or less
DTime of concentrated spray to one point: within 30 sec.
Approx.
40 cm

GENERAL -Supplemental Restraint System (SRS)00-22
SRS SERVICE PRECAUTIONS
1. In order to avoid injury to yourself or others
from accidental deployment of the air bag and
accidental operation of the seat belt with
pre-tensioner during servicing, read and
carefully follow all the precautions and
procedures described in this manual.
2. Do not use any electrical test equipment on
or near SRS components, except those
specified on P.52B-6.
3. Never Attempt to Repair the Following
Components:
DSRS air bag control unit (SRS-ECU)
DClock spring
DDriver’s and front passenger’s air bag
modules
DSeat belt with pre-tensionerNOTE
If any of these components are diagnosed as
faulty, they should only be replaced, in
accordance with the INDIVIDUAL COM-
PONENTS SERVICE procedures in this
manual. (Refer to P.52B-49.)
4. After disconnecting the negative (–) battery cable,
wait 60 seconds at least before any service and
insulate the disconnected cable with tape. The SRS
retain enough voltage to deploy the air bags for a
short time even after the disconnection of the battery.
So, serious injury may result by accidental air bag
deployment if a work is done on the SRS just after
the disconnection of the battery.
5. Do not attempt to repair the wiring harness connectors
of the SRS. If the connector(s) are diagnosed as defective,
replace the wiring harness(es). If the harness(es) are
diagnosed as faulty, replace or repair the wiring
harness(es) according to the table that follows.

10. Turn the ignition switch to the “LOCK” (OFF) position
and then remove the MUT-II.
COMPRESSION PRESSURE CHECK
1. Before inspection, check that the engine oil, starter and
battery are normal. In addition, set the vehicle to the
pre-inspection condition.
2. Remove the ignition coils and spark plug cables.
3. Remove all of the spark plugs.
4. Disconnect the crank angle sensor connector.
NOTE
Doing this will prevent the engine-ECU from carrying out
ignition and fuel injection.
5. Cover the spark plug hole with a shop towel etc., and
after the engine has been cranked, check that no foreign
material is adhering to the shop towel.
Caution
(1) Keep away from the spark plug hole when
cranking.
(2) If compression is measured with water, oil, fuel,
etc., that has come from cracks inside the cylinder,
these materials will become heated and will gush
out from the spark plug hole, which is dangerous.
6. Set compression gauge to one of the spark plug holes.
7. Crank the engine with the throttle valve fully open and
measure the compression pressure.
Standard value (at engine speed of 250 r/min):
1,128 kPa
Limit (at engine speed of 250 r/min):
Min. 951 kPa
8. Measure the compression pressure for all the cylinders,
and check that the pressure differences of the cylinders are
below the limit.
Limit: Max. 98 kPa
9. If there is a cylinder with compression or a compression
difference that is outside the limit, pour a small amount
of engine oil through the spark plug hole, and repeat
the operations in steps 7 and 8.
(1) If the compression increases after oil is added, the
cause of the malfunction is a worn or damaged piston
ring and/or cylinder inner surface.
(2) If the compression does not rise after oil is added,
the cause is a burnt or defective valve seat, or pressure
is leaking from the gasket.
10. Connect the crank angle sensor connector.
11. Install the spark plugs.

12. Install the ignition coils and spark plugs.
13. Use the MUT-IIto erase the self-diagnosis codes or
disconnect the battery cable from the battery ( - ) terminal
for 10 seconds or more and then reconnect the cable.
NOTE
This will erase the diagnosis code resulting from the crank
angle sensor connector being disconnected.
MANIFOLD VACUUM CHECK
1. Set the vehicle to the pre-inspection condition.
2. Turn the ignition switch to the “LOCK” (OFF) position.
3. Set the engine tachometer or connect the MUT-II.
4. Check that the idle speed is within the standard value.
NOTE
When using the MUT-II, select the code No.22.
5. Connect the three-way union joint to the vacuum hose
between the fuel pressure control valve and the air intake
plenum, and connect a vacuum gauge.
6. Check the manifold vacuum at idle.
Limit: 58 kPa
7. Turn the ignition switch to the “LOCK” (OFF) position.
8. Remove the vacuum gauge and install the vacuum hose
in its original location.
9. Remove the engine tachometer or the MUT-II.
LASH ADJUSTER CHECK
If an abnormal noise (knocking) that seems to be coming
from the lash adjuster is heard after starting the engine and
does not stop, carry out the following check.
NOTE
(1) The abnormal noise which is caused by a problem
with the lash adjusters is generated after the engine
is started, and will vary according to the engine speed.
However, this noise is not related to the actual engine
load.
Because of this, if the noise does not occur
immediately after the engine is started, if it does not
change in accordance with the engine speed, or if
it changes in accordance with the engine load, the
source of the noise is not the lash adjusters.

ENGINE -Timing Belt and Timing Belt B11A-37

(1) Connect the special tool (MB991668) to the MUT-II.
(2) Connect the special tool (MB991704) to the MUT-II
and the battery.
(3) Rotate the crankshaft clockwise for two rounds to
position No.1 cylinder at compression TDC and check
that timing marks of each sprocket are aligned with
each other.
(4) Select “Belt Tension Measurement” from the menu
screen of the MUT-II.
(5) Hold the special tool (MB991668) to the middle of
the belt between sprockets (at the place indicated
by the arrow) as shown in the illustration about 10
- 20 mm away from the rear surface of the belt and
so that it is perpendicular to the belt (within an angle
of±15_).
(6) Gently tap the middle of the belt between sprockets
(the place indicated by the arrow) with your finger
as shown in the illustration and check that the vibration
frequency of the belt is within the standard value.
Caution
1) If strong gusts of wind blow against the
microphone or if there are any loud sources
of noise nearby, the values measured by the
microphone may not correspond to actual
values.
2) If the microphone is touching the belt while
the measurement is being made, the values
measured by the microphone may not
correspond to actual values.

Apply a force of approx.100N to the middle (arrow part)
of pulley shown in the figure, and check that the deflection
is within the standard value.
3. If it is outside the standard value, re-adjust belt tension.
