8. If the basic ignition timing is outside the standard 

value, inspect the MPI system (Refer to GROUP 
13A 

− Troubleshooting − Inspection chart for 

trouble symptom ).

CAUTION

If the test is not cancelled, a forced driving will 
continue for 27 minutes. Driving under this con-
dition may damage the engine.

9. Cancel the actuator test function item No. 11, 

Basic ignition timing set mode, on the M.U.T-III.

10.Check that ignition timing is at the standard value.

Standard value: approximately 10

° BTDC

NOTE: 

.

•

The ignition timing may fluctuate within 

±

 7

°

. 

This is normal.

•

In higher altitude, the ignition timing is more 
advanced than the standard value by approxi-
mately 5

°

.

•

Wait till approximately 1 minute passes after 
the engine started, and check the ignition tim-
ing when the engine stabilized.

11.Remove the timing light.

12.Turn the ignition switch to the "LOCK" (OFF) 

position and then disconnect the M.U.T.-III.

the idle speed control system.

•

When using the M.U.T.-III, select item No. 2 
and take a reading of the idle speed.

8. If the idle speed is outside the standard value, 

inspect the MPI system (Refer to GROUP 13A 

−

NOTE: Perform the valve clearance check and 
adjustment at the engine cold state.
1. Remove all ignition coils.

2. Remove the cylinder head cover.

CAUTION

Turn the crankshaft always clockwise.

3. Turn the crankshaft clockwise, and align the 

timing mark on the exhaust camshaft sprocket 
against the upper face of the cylinder head as 
shown in Figure. Therefore, No.1 cylinder goes to 
the compression top dead centre.

Confirm the clearance is within the standard 
value.

CAUTION

Completely remove all the old liquid gasket, 
which might be remaining among the compo-
nents.

COMPRESSION PRESSURE CHECK

M1111002604155

1. Before inspection, set the vehicle to the 

pre-inspection condition.

2. Disconnect the ignition coil connectors and then 

remove all of the ignition coils and spark plugs.

connectors

3. Disconnect the all of the injector connectors.

CAUTION

• Keep away from the spark plug hole when 

cranking.

• If compression is measured with water, oil, 

fuel, etc., that has come from cracks inside 
the cylinder, these materials will become 
heated and will gush out from the spark plug 
hole, which is dangerous.

4. Cover the spark plug hole with a shop towel etc., 

and after the engine has been cranked, check that 
no foreign material is adhering to the shop towel.

AK502604AD

Compression gauge

5. Set compression gauge to one of the spark plug 

holes.

6. Crank the engine with the throttle valve fully open 

and measure the compression pressure.

Standard value (at engine speed of 200 

r/min):

1,470 kPa <4B11>
1,440 kPa <4B12>

Limit (at engine speed of 200 r/min): 
Minimum 1,000 kPa

7. Measure the compression pressure for all the 

cylinders, and check that the pressure differences 
of the cylinders are below the limit.

Limit: Maximum 98 kPa
