1. INSPECT ENGINE COOLANT (See page CO-2)

2. INSPECT ENGINE OIL (See page LU-2)

3. INSPECT BATTERY (See page CH-4)

4. INSPECT AIR CLEANER FILTER ELEMENT SUB-ASSEMBLY

5. INSPECT SPARK PLUG (See page IG-5)

6. INSPECT DRIVE BELT

(a) Visually check the driver belt for excessive wear, frayed cords, etc. If any defect is found, replace the drive belt. HINT:

Cracks on the rib side of a drive belt are considered acceptable. If the drive belt has chunks missing from the ribs, it should be replaced.

7. INSPECT IGNITION TIMING NOTICE:

• Turn all electrical systems OFF.

• Operate the inspection when the cooling fan motor is turned OFF.

(b) When using the intelligent tester.

(1) Connect the intelligent tester to the DLC3.

(2) Select the following menu items: DIAGNOSIS / ENHANCED OBD ll / DATA LIST / IGN ADVANCE.

(3) Inspect the ignition timing during idling. Ignition timing:

7 to 24°CA BTDC during idling (Transmission in neutral position)

(4) Check that the ignition timing advances immediately when the engine speed is increased.

(c) When not using intelligent tester.

(1) Using SST, connect the terminals 13 (TC) and 4 (CG) of the DLC3.

SST 09843-18040 NOTICE:

Be sure not to connect the terminals wrongly. It causes breakage of the engine.

(2) Remove the air cleaner.

(3) Pull out the wire harness as shown in the illustration.

(4) Connect the tester probe of a timing light to the wire of the ignition coil connector for No. 1 cylinder.

NOTICE:

• Use a timing light that detects the first signal.

• After checking, be sure to wrap the wire harness with tape.

(5) Inspect the ignition timing during idling. Ignition timing:

8 to 12°CA BTDC during idling (Transmission in neutral position)

(6) Remove the SST from the DLC3.

(7) Inspect the ignition timing during idling. Ignition timing:

7 to 24°CA BTDC during idling (Transmission in neutral position)

(8) Install the air cleaner.

8. INSPECT ENGINE IDLING SPEED NOTICE:

• Turn all the electrical systems OFF.

• Operate the inspection when the cooling fan motor is turned OFF.

(b) When using the intelligent tester:

(1) Connect the intelligent tester to the DLC3.

(2) Select the following menu items: DIAGNOSIS / ENHANCED OBD ll / DATA LIST / ENGINE SPD.

(3) Inspect the engine idling speed. Idling speed:

650 to 750 rpm (Transmission in neutral position)

(c) When not using the intelligent tester:

(1) Using SST, connect the terminal 8 (TAC) of the DLC3.

SST 09843-18030

(2) Race the engine speed at 2,500 rpm for approximately 90 seconds.

(3) Inspect the engine idling speed. Idling speed:

650 to 750 rpm (Transmission in neutral position)

9. INSPECT COMPRESSION

(a) Warm up and stop the engine.

(b) Remove the circuit opening relay.

(c) Remove the V-bank cover.

(d) Remove the air cleaner assembly.

(e) Remove the ignition coils.

(f) Remove the spark plugs.
