harness

For vehicles with CAN
communication, use M.U.T.-III
main harness A to send
simulated vehicle speed. If you
connect M.U.T.-III main harness
B instead, the CAN
communication does not
function correctly.

PRESSURE CHECK

M1151001001069

CAUTION

Conduct the driving test in a location where driv-
ing at full acceleration can be done with safety.
Two person should be in the vehicle when the
test is conducted; the person in the passenger
seat should read the indications shown by the
M.U.T.-III.

1. Set the vehicle to the pre-inspection condition.

2. Turn the ignition switch to "LOOK" (OFF) position,

and connect the diagnosis connector to the
M.U.T.-III.

3. Use the data list function named "Item No. 6"

boost pressure sensor of the M.U.T.-III to check
the supercharging pressure when the engine
speed increases to approximately 3,000 r/min or
more by driving at full acceleration in 2nd.

Standard value:

178.9

− 188.2 kPa <Except Euro 5>

194.9

− 233.5 kPa <Euro 5-low power engine>

199.4

− 237.6 kPa <Euro 5-normal power

engine>

203.1

− 238.6 kPa <Euro 5-high power engine>

4. If the supercharging pressure deviates from the

standard value, check the following items for
possible cause.

• Malfunction of the waste gate actuator <Except

Euro 5>

• Malfunction of the variable geometry actuator

<Euro 5>

• Malfunction of the variable geometry solenoid

valve <Euro 5>

• Malfunction of the variable nozzle <Euro 5>

• Malfunction of the boost pressure sensor

• Leakage of supercharging pressure

• Malfunction of the turbocharger

5. When the indicated supercharging is more than

standard value, supercharging control may be
faulty, therefore check the followings.

• Disconnection or cracks of the waste gate actua-

tor rubber hose <Except Euro 5>

• Malfunction of the waste gate actuator <Except

Euro 5>

• Malfunction of the waste gate valve <Except Euro

5>

• Malfunction of the variable geometry actuator

<Euro 5>

• Malfunction of the variable geometry solenoid

valve <Euro 5>

• Malfunction of the variable nozzle <Euro 5>

• Malfunction of the manifold absolute pressure

sensor

WASTE GATE ACTUATOR CHECK
<Except Euro5>

M1151001200673

AK403495

1. Connect a manual pump (pressure-application

type) to nipple.

CAUTION

In order to avoid damage to the diaphragm, do
not apply a pressure of 159 kPa or higher.
2. While gradually applying pressure, check the

pressure that begins to activate (approximately 1
mm stroke) the waste gate actuator rod.

Standard value:

132.6

− 143.6 kPa

3. If there is a significant deviation from the standard

value, check the actuator or the waste gate valve:
replace actuator or turbocharger assembly if
necessary.

VARIABLE GEOMETRY ACTUATOR
CHECK <EURO5>

Variable geometry actuator

1. Remove the vacuum hose from the variable

geometry (VG) actuator. Connect the hand
vacuum pump to the nipple.

Stopper bolt

Variable geometry
actuator

AB

CAUTION

In order to avoid damage to the diaphragm, do
not apply a vacuum of 60 kPa or higher.
2. By applying the vacuum pressure until the VG

actuator link touches the stopper bolt, fully shrink
the actuator rod. The vacuum pressure is
approximately 55 kPa at that time.

3. Leak the vacuum pressure gradually as much as

possible to check the vacuum pressure when the
VG actuator rod moves approximately 1.5 mm in
the extension direction.

Standard value: Approximately 45.4

− 49.2

kPa

4. If the vacuum pressure significantly deviates from

the standard value, check the actuator or the
variable nozzle. Replace the turbocharger
assembly if necessary.

Variable geometry
control solenoid valve

1. Disconnect the vacuum hoses from the variable

geometry solenoid valve.
NOTE: When disconnecting the vacuum hose,
always make sure that it can be reconnected at its
original position.

2. Disconnect the harness connector.

3. Connect a hand vacuum pump to nipple (A) of the

variable geometry solenoid valve.

4. As described in the chart below, check

airtightness by applying a vacuum with voltage
applied directly from the battery to the variable
geometry solenoid valve, and without applying
voltage.

5. Measure the resistance between the terminals of

the variable geometry solenoid valve.

Standard value: 10

− 14 Ω (at 20°C)

6. Replace the solenoid if airtightness or resistance

is out of specification.
