7. INSPECT IGNITION TIMING
(a) Warm up engine.
(b) When using hand±held tester:(1) Connect the hand±held tester to the DLC3.
(2) Enter DATA LIST MODE on the hand±held tester.
Ignition timing: 8 to 12  BTDC
HINT:
Please refer to the hand±held tester operator's manual if you
need help to select DATA LIST.
(c) When not using hand±held tester:
(1) Using SST, connect terminals 13 (TC) and 4 (CG)of DLC3.
SST 09843±18040
NOTICE:

Make sure of the terminal numbers before connecting
them. Connection with a wrong terminal can damage
the engine.

Turn OFF all electrical systems before connecting the
terminals.

Operate the inspection after the cooling fan motor is
turned OFF.
(2) Remove the cylinder head cover No.2.
(3) Pull out the wire harness as shown in the illustration.
Connect the clip of the timing light to the engine.
NOTICE:

Use a timing light which detects the first signal.

After checking, be sure to wrap the wire harness with
tape.
(4) Inspect ignition timing at idle.
Ignition timing: 8 to 12  BTDC
NOTICE:
When checking the ignition timing, shift the transmission
to the neutral position.
HINT:
Run the engine at 1,000 to 1,300 rpm for 5 seconds, check that
the engine rpm returns to the idle speed.

(5) Disconnect terminals 13 (TC) and 4 (CG) of DLC3.
(6) Inspect ignition timing at idle.
Ignition timing: 5 to 15  BTDC
(7) Confirm that ignition timing to go advanced angle side when the engine rpm is increased.
(8) Remove the timing light.
8. INSPECT ENGINE IDLE SPEED
(a) Warm up engine.
(b) When using hand±held tester:
(1) Connect the hand±held tester to the DLC3.
Idle speed: 650 to 750 rpm
NOTICE:

Check the idle speed with the cooling fan OFF.

Switch off all accessories and air conditioning before
connecting the test prove to the terminal.
HINT:
Please refer to the hand±held tester operator's manual if you
need help to select DATA LIST.
(c) When not using hand±held tester.
(1) Using SST, connect the tachometer test prove toterminal 9 (TAC) of DLC3.
SST 09843±18040
(2) Check the idle speed.
Idle speed: 650 to 750 rpm
9. INSPECT COMPRESSION
(a) Warm up and stop the engine.
(b) Disconnect the injector connectors.
(c) Remove the ignition coil.
(d) Remove the spark plugs.
(e) Inspect cylinder compression pressure. SST 09992±00500
(1) Insert a compression gauge into the spark plughole.
(2) Fully open the throttle.

(3)While cranking the engine, measure the compres-
sion pressure.
Compression pressure:
1,300 kPa (13.3 kgf/cm
2, 189 psi)
Minimum pressure:
1000 kPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 14 psi)
NOTICE:

Always use a fully charged battery to obtain engine
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 is low, pour a small amount of engine oil into the cylinder through the
spark plug hole and 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, a valve may be sticking or seating
improperly, or there may be leakage past the gasket.
10.INSPECT CO/HC
(a)Start the engine.
(b)Run the engine at 2,500 rpm for approximately 180 seconds.
(c)Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into the tail\
pipe during idling.
(d)Check CO/HC concentration at idle. Idle CO concentration: 0 to 0.5 %
Idle HC concentration: Applicable local regulation
(e)If the CO/HC concentration does not conform to specifications, perform troubleshooting 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 repair the applicable causes ifnecessary.
