This system has a swirl control valve in the intake passage of each cylinder.
While idling and during low engine speed operation, the swirl control valve closes. Thus the velocity of the air
in the intake passage increases, promoting the vaporization of the fuel and producing a swirl in the combus-
tion chamber.
Because of this operation, this system tends to increase the burning speed of the gas mixture, improve fuel
consumption, and increase the stability in running conditions.
Also, except when idling and during low engine speed operation, this system opens the swirl control valve.
The solenoid valve controls swirl control valve’s shut/open condition. This solenoid valve is operated by the
ECM.

Component Description

NLEC0525

SWIRL CONTROL VALVE CONTROL SOLENOID VALVE

NLEC0525S01

The swirl control valve control solenoid valve responds to signals
from the ECM. When the ECM sends an ON (ground) signal, the
solenoid valve is bypassed to apply intake manifold vacuum to the
swirl control valve actuator. This operation closes the swirl control
valve. When the ECM sends an OFF signal, the vacuum signal is
cut and the swirl control valve opens.

1) Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to use

coolant with the proper mixture ratio. Refer to MA-20, “Anti-freeze Coolant Mixture Ratio”, “RECOM-
MENDED FLUIDS AND LUBRICANTS”.

Overall Function Check

NLEC0489

Use this procedure to check the overall function of the cooling fan.
During this check, a DTC might not be confirmed.

WARNING:

Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by
turning it a quarter turn to allow built-up pressure to escape.
Then turn the cap all the way off.

With CONSULT-II

1)

Check the coolant level and mixture ratio (using coolant tester)
in the reservoir tank and radiator.
Allow engine to cool before checking coolant level and
mixture ratio.

+

If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to “Diagnos-
tic Procedure”, EC-378.

+

If the coolant mixture ratio is out of the range of 45 to 55%,
replace the coolant in the following procedure LC-19, “Chang-
ing Engine Coolant”.

2)

Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to “Diagnos-
tic Procedure”, EC-378.

3)

Turn ignition switch “ON”.

4)

Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II.

5)

If the results are NG, go to “Diagnostic Procedure”, EC-378.

Without CONSULT-II

1)

Check the coolant level and mixture ratio (using coolant tester)
in the reservoir tank and radiator.
Allow engine to cool before checking coolant level and
mixture ratio.

2)

Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to “Diagnos-
tic Procedure”, EC-378.

3)

Start engine.
Be careful not to overheat engine.

4)

Set temperature control lever to full cold position.

5)

Turn air conditioner switch “ON”.

6)

Turn blower fan switch “ON”.

7)

Run engine at idle for a few minutes with air conditioner oper-
ating.
Be careful not to overheat engine.
