HINT:
After installing the drive belt, check that it fits properly in the ribbed grooves. Check with your hand to confirm that the belt has not slipped out of the groove on the bottom of the crank pulley.
”New belt” is a belt which has been used less than 5 minutes on a running engine.
”Used belt” is a belt which has been used on a running engine for 5 minutes or more.
After installing a new belt, run the engine for approximately 5 minutes and then recheck the tension.
7. INSPECT IGNITION TIMING
a. Warm up the engine.
b. When using the hand−held tester: Check the ignition timing.
Connect the hand−held tester to the DLC3.
Enter DATA LIST MODE on the hand−held tester.
Ignition timing: 8 to 12 BTDC @ idle
HINT: Please refer to the hand−held tester operator’s manual for help on selecting the DATA LIST.
c. When not using the hand−held tester: Check the ignition timing.
1. Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3.
SST 09843−18040
NOTICE:
Confirm the terminal numbers before connecting them. Connection with a wrong terminal can damage the engine.
Turn off all electrical systems before connecting the terminals.
Perform this inspection after the cooling fan motor is turned off.
Remove the cylinder head cover No. 2.
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 can detect the first signal.
After checking, be sure to tape the wire harness.
4. Check the ignition timing at idle.
Ignition timing: 8 to 12 BTDC @ idle
NOTICE: When checking the ignition timing, the transmission should be in the neutral position.
HINT: After engine rpm is kept at 1,000 to 1,300 rpm for 5 seconds, check that it returns to idle speed.
Disconnect terminals 13 (TC) and 4 (CG) of the DLC3.
Check the ignition timing at idle.
Ignition timing: 5 to 15 BTDC @ idle
Confirm that ignition timing moves to the advanced angle side when the engine rpm is increased.
Remove the timing light.
8. INSPECT ENGINE IDLE SPEED
a. Warm up the engine.
b. When using the hand−held tester: Check the idle speed.
1. Connect the hand−held tester to the DLC3.
HINT: Please refer to the hand−held tester operator’s manual for further details.
2. Enter DATA LIST MODE on the hand−held tester.
Idle speed:

NOTICE: When checking the idle speed, the tranmission should be in the neutral position.
Check idle speed with the cooling fan off.
Switch off all accessories and air conditioning before connecting the hand−held tester.
c. When not using the hand−held tester: Check the idle speed.
Using SST, connect tachometer tester probe to terminal TAC) of the DLC3.
SST 09843−18030
Check the idle speed.]
Idle speed:
9. INSPECT COMPRESSION
Warm up and stop the engine.
Disconnect the injector connectors.
Remove the ignition coils.
Remove the spark plugs.
e. Check the cylinder compression pressure.
Insert a compression gauge into the spark plug hole.
Fully open the throttle.
While cranking the engine, measure the compression pressure.
Compression pressure:

Minimum pressure:
Difference between each cylinder:
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 as quickly 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 stuck or seated improperly, or there may be leakage in the gasket.
10. INSPECT CO/HC
Start the engine.
Rev the engine at 2,500 rpm for approximately 180 seconds.
Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into the tailpipe during idling.
Immediately check CO/HC concentration at idle and/or 2,500 rpm.
HINT:
Complete the measuring within 3 minutes.
Check regulations and restrictions in your area when performing 2 mode CO/HC concentration testing (engine check at both idle speed and at 2,500 rpm).
e. If the CO/HC concentration does not comply with regulations, troubleshoot in the order given below.
Check A/F operation (see page 05−288).
See the table below for possible causes, and then inspect and repair.
