INSPECT FAN AND GENERATOR V BELT
HINT:
You don’t need to check the belt deflection because auto tensioner is adopted.
7. INSPECT IGNITION TIMING
(a) Warm up engine.
(b) When using hand–held tester or OBDII scan tool.
(1) Connect the hand–held tester or OBDII scan tool to
the DLC3.
HINT:
Please refer to the hand–held tester or OBDII scan tool opera-
tor’s manual for further details.
TC
(c) When not using hand–held tester or OBDII scan tool.
(1) Using SST, connect terminal 13 (TC) and 4 (CG) of
the DLC3.
SST 09843–18040
NOTICE:
Be sure not to connect incorrectly. It causes breakage
of the engine.
Turn OFF all electrical systems.
Operate the inspection when the cooling fan motor is
turned OFF
(2) Remove the 2 nuts, 2 clips and cylinder head cover.
(3) Pull out the wire harness as shown in the illustration.
(4) Connect the clip of the timing light to the engine.
NOTICE:
CG
A62199
Use a timing light which can detect the first signal.
After checking, be sure to tape the wire harness.

(5) Inspect ignition timing at idle.
Ignition timing: 8 – 12
BTDC
NOTICE:
When checking the ignition timing, the transmission is at
neutral position.
HINT:
After engine rpm is kept at 1,000 – 1,300 rpm for 5 seconds,
check that it returns idle speed.

(8) Confirm that ignition timing moves to advanced
angle side when the engine rpm is increased.

8. INSPECT ENGINE IDLE SPEED
(a) Warm up engine.
(b) When using hand–held tester or OBDII scan tool.
(1) Connect the hand–held tester or OBDII scan tool to the DLC3.
HINT:
Please refer to the hand – held tester or OBDII scan tool operator’s manual for further details.
(c) Check the idle speed.
Idle speed: 650 – 750 rpm
NOTICE:
Check idle speed with cooling fan OFF.
Switch off all accessories and air conditioning.

9. INSPECT COMPRESSION
(a) Warm up and stop engine.
(b) Remove ignition coil.
(c) Remove spark plugs.
(d) Inspect cylinder compression pressure.
SST 09992–00500
(1) Insert a compression gauge into the spark plug
hole.
(2) Fully open the throttle.
(3) While cranking the engine, measure the compres-
sion pressure.

speed of 250 rpm or more.
Check other cylinder’s compression pressure in the
same way.
This measurement must be done in as short a time as
possible.

(4) If the cylinder compression in one more cylinders is
low, pour a small amount of engine oil into the cylin-
der through the spark plug hole and repeat steps (1)
through (3) for cylinders with low compression.
HINT:
If adding oil helps the compression, it is likely that the pis-
ton rings and/or cylinder bore are worn or damaged.
If pressure stays low, a valve may be sticking or seating
is improper, or there may be leakage past the gasket.
10. INSPECT CO/HC
(a) Start the engine.
(b) Race engine at 2,500 rpm for approx. 180 seconds.
(c) Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into tailpipe during idling.
(d) Immediately check CO/HC concentration at idle and/or 2,500 rpm.
HINT:
Complete the measuring within 3 minutes.
When doing the 2 mode (idle and 2,500 rpm) test, these measuring orders are prescribed by the appli-
cable local regulations.
(e) If the CO/HC concentration does not comply with regulations, troubleshoot in the order given below.
(1) Check heated oxygen sensor operation. (See page
12–6
)
(2) See the table below for possible causes, and then inspect and correct the applicable causes if
necessary.
