NOTICE:
Check the drive belt deflection at the specified point.
When installing a new belt, set its tension value as
specified.
When inspecting a belt which is used for over 5 min-
utes, apply the specification of ºUsed beltº.
When reinstalling a belt which is used for over 5 min-
utes, adjust its belt deflection and tension to the inter-
mediate value of each specification in ºUsed beltº.
The V- ribbed belt tension and deflection value
should be checked after 2 revolutions of engine
cranking.
When using a belt tension gauge, confirm the accura-
cy first by using a master gauge.
7. INSPECT IGNITION TIMING
(a) Warm up engine.
(b) When using the hand-held tester or OBD II scan tool:
(1) Connect the hand-held tester or OBD II scan tool
to the DLC3.

OBD II scan tool.
Ignition timing: 8 to 12 BTDC
HINT:
Refer to the hand-held tester or OBD II scan tool operator's
manual if you need help to select DATA LIST.

(c) When not using the hand-held tester or OBD II scan tool:
(1) Using SST, connect terminals 13 (TC) and 4 (CG)
of the DLC3.
SST 09843-18040
NOTICE:
Make sure of the terminal numbers before connecting
them. Connecting wrong terminals can damage the
engine.
Turn OFF all electrical systems before connecting the
terminals.
Perform this inspection after the cooling fan motor is
turned OFF.
(2) Remove the V-bank cover.
(3) Pull out the engine wire colored by black and red as
shown in the illustration.
(4) Connect the tester terminal of the timing light to the
engine.
NOTICE:
Use a timing light which detects the first signal.
(5) Inspect the ignition timing at idle.
Ignition timing: 8 to 12 BTDC
NOTICE:
When checking the ignition timing, the transmission is in
the neutral position.
HINT:
Run the engine at 1,000 to 1,300 rpm for 5 seconds, then check
that the engine speed returns to the idle speed.
(6) Disconnect terminals 13 (TC) and 4 (CG) of the
DLC3.
(7) Inspect the ignition timing at idle.
Ignition timing: 7 to 24 BTDC
(8) Confirm that the ignition timing advances when the
engine speed is increased.
(9) Remove the timing light.
8. INSPECT ENGINE IDLE SPEED
(a) Warm up the engine.
(b) When using the hand-held tester or OBD II scan tool:
(1) Connect the hand-held tester or OBD II scan tool to the DLC3.
(2) Enter DATA LIST MODE on the hand-held tester or OBD II scan tool.
Idle speed: 630 to 730 rpm
NOTICE:
When checking the idle speed, the transmission is in the neutral position.
Check the idle speed with the cooling fan OFF.
Switch OFF all accessories and air conditioning before connecting the hand-held tester or OBD
II scan tool.
HINT:
Refer to the hand-held tester or OBD II scan tool operator's manual for further details.

9. INSPECT COMPRESSION
(a) Warm up and stop the engine.
(b) Remove the intake air surge tank (see page 11-13).
(c) Disconnect the injector connectors.
(d) Remove the ignition coils.
(e) Remove the spark plugs.
(f) Inspect the cylinder compression pressure.
(1) Insert a compression gauge into the spark plug
hole.
SST 09992-00500
(2) Fully open the throttle.
(3) While cranking the engine, measure the compres-
sion pressure.
Compression pressure:
1.5 MPa (15.3 kgf/cm
2, 218 psi)
Minimum pressure:
1.0 MPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 15 psi)
NOTICE:
Always use a fully-charged battery to obtain engine
speed of 250 rpm or more.
Check the other cylinder's compression pressure in
the same way.
This measurement must be done as quickly as pos-
sible.
(4) If the cylinder compression is low, pour a small
amount of engine oil into the cylinder through the
spark plug hole, then inspect again.
HINT:
If adding oil increases the compression, the piston rings
and/or cylinder bore may be worn or damaged.
If pressure stays low, the valve may be sticking or seated
improperly, or there may be leakage past the gasket.
10. INSPECT CO/HC
HINT:
The ECM properly controls the CO/HC concentration in the emission gas.
(a) Start the engine.
(b) Run the engine at 2,500 rpm for approximately 180 seconds.
(c) Insert the CO/HC meter testing probe at least 40 cm (1.3 ft) into the tailpipe during idling.
(d) Check the CO/HC concentration at idle and/or at 2,500 rpm.
HINT:
When doing the 2 mode (with the engine is at idle and at 2,500 rpm) tests, these measuring order are pre-
scribed by the applicable local regulations.
If the CO/HC concentration does not comply with the regulations, troubleshoot in the order given below.
(1) Check the heated oxygen sensor operation (see page 05-126).
