Boost Pressure Control Solenoid Valve
Inspection

S6JB0A1326030

1) Remove boost pressure control solenoid valve

referring to “Boost Pressure Control Solenoid Valve
Removal and Installation: For Diesel Engine Model”.

2) Check the resistance between terminals of boost

pressure control solenoid valve is within
specification.
If resistance is not as specified, replace boost
pressure control solenoid valve.

Boost pressure control solenoid valve resistance
14.7 – 16.1

Ω at 20 °C, 68 °F

3) Using special tool, check operation of boost

pressure solenoid valve as follows.

Special tool
(A): 09917–47011

a) Check if vacuum is applied at nozzle “a” with

nozzle “b” blocked off.
If vacuum is applied, replace solenoid valve.

b) Connect battery to solenoid valve as shown in

figure.
In this state, check if vacuum is applied up to 40
kPa (0.4 kg/cm

2

, 5.7 psi) in the same manner as

step a).
If applied vacuum is lower than specified value,
replace solenoid valve.

NOTE

• It is necessary to pump lever of special

tool several times quickly in order to
increase vacuum up to specified value.

• Valve does not hold vacuum but it does not

indicate anything faulty.

Turbocharger Electric Water Pump Inspection

S6JB0A1326032

1) Connect 12 V battery terminals to turbocharger

electric water pump terminals.

2) Check if turbocharger electric water pump operates

smoothly without noise.

3) Check if ammeter indicates the specified current.

If measured current is out of specification, replace
turbocharger electric water pump.

Turbocharger electric water pump current at 12 V
1 – 1.3 A at 23

°C, 73 °F

4) Check pumping rate.

Turbocharger electric water pump pumping rate:
More than 850 L/h. (1796 US pt./h., 1496 Imp pt./
h.). at 23

°C, 73 °F

Mass Air Flow (MAF) and Intake Air
Temperature (IAT) Removal and Installation

S6JB0A1326033

Removal

1) Disconnect negative cable at battery.
2) Disconnect MAF and IAT sensor connector (1).
3) Remove MAF and IAT sensor (2) from air cleaner

(3).

Installation
Reverse removal procedure noting the followings.
• Tighten MAF and IAT sensor screws to specified

torque.

Tightening torque
MAF and IAT sensor screw: 6 N·m (0.6 kgf-m, 4.5
lb-ft)

• Tighten turbocharger inlet hose clamp to specified

torque.

Tightening torque
Inlet hose clamp: 2.5 N·m (0.25 kgf-m, 2.0 lb-ft)

• Connect MAF and IAT sensor connector securely.

Mass Air Flow (MAF) and Intake Air
Temperature (IAT) Sensor Inspection

S6JB0A1326034

CAUTION

!

Do not heat up MAF and IAT sensor more
than 100

°C (212 °F). Otherwise, MAF and IAT

sensor will be damaged.

• Check sensor O-ring (1) for damage and

deterioration. Replace as necessary.

• Blow hot air to temperature sensing part (2) of MAF

and IAT sensor (3) using hot air drier (4) and measure
resistance between sensor terminals while heating air
gradually.
If measured resistance does not show such
characteristic as shown, replace MAF and IAT sensor.

Intake air temperature sensor resistance
10

°C (50 °F): 3.55 – 3.87 kΩ

20

°C (68 °F): 2.35 – 2.54 kΩ

Inlet Throttle Valve On-Vehicle Inspection

S6JB0A1326036

CAUTION

!

Do not disassembly inlet throttle valve.

1) Connect SUZUKI scan tool to data link connector

(DLC) with ignition switch OFF.

2) Check that no abnormality is detected in ECM.

Refer to “DTC Check: For Diesel Engine Model in
Section 1A”.

3) Turn ignition switch to ON position and select menu

“Electronic Throttle Control” under “Miscellaneous
test” (“MISC. TEST”) mode of SUZUKI scan tool.
Follow the instructions indicated on the SUZUKI
scan tool.

NOTE
For further details, refer to the operator’s
manual for SUZUKI scan tool.

4) Confirm the inlet throttle valve operates five times. If

inlet throttle valve does nit operate, replace inlet
throttle valve referring to “Inlet Throttle Valve
Removal and Installation: For Diesel Engine Model”.

CAUTION

!

When replacing inlet throttle valve, perform
“Initialize inlet throttle valve date” mode of
SUZUKI scan tool referring to “Inlet Throttle
Valve Data Initialization: For Diesel Engine
Model”.
