5. Connect the special tool (MB991658) to the harness side
of the engine coolant temperature sensor connector.
6. Connect the special tool [MB991791(APS)] to the special
tool (MB991658).
7. Start the engine and let it run at idle.
NOTE
Since the resistance value of the special tool (APS)
indicates a low engine coolant temperature, engine speed
increases.
8. When the lever of the special tool (APS) is turned to
the end, check that the engine speed decreases and
the radiator fan motor rotates.
9. When the lever of the special tool (APS) is turned to
the reverse direction, check that the voltage between
terminals of the radiator fan motor connector gradually
decreases from the battery voltage to 0 V.
10. If inoperable, replace the radiator fan controller.
(Refer to P.14-15.)
11. Install the center under cover.
(Refer to GROUP 51 - Front Bumper.)
12. Connect the engine coolant temperature sensor
connector.

1. Remove the center under cover.
(Refer to GROUP 51 - Front Bumper.)
2. Insert the special tool at the back of the radiator fan
motor connector.
3. Connect the special tool to the circuit tester.
4. Start the engine and run it at idle.
5. Turn the A/C switch to the ON position and hold the
engine coolant temperature at 80_C or lower.
6. When the voltage between the terminals of the radiator
fan motor connector, the following values of (1) - (3)
can be detected at random.
(1) 0 V
(2) 8.22.6 V
(3) Battery voltage2.6 V
7. If inoperable, replace the radiator fan controller.
(Refer to P.14-15.)
8. Install the center under cover.

TURBOCHARGER SUPERCHARGING
PRESSURE CHECK
Caution
Two persons should be in the vehicle when the test is
conducted; the person in the passenger seat should read
the indications shown by the pressure meter.
1. Disconnect the hose (black) from the turbocharger waste
gate solenoid valve, and connect the pressure gauge
to the hose. Plug the nipple of the solenoid valve from
which the hose (black) has been disconnected.
2. Drive at full-throttle acceleration in second gear and then
measure the supercharging pressure when the engine
speed in about 3,000 r/min.
Standard value: 59 – 84 kPa
3. If the supercharging pressure deviates from the standard
value, check the following items for possible cause.
