11. FUEL PUMP RELAY NO.2 CHECK
(1) Remove fuel pump relay No.2.
(2) Using jumper wires, connect fuel pump relay No.2 terminal
(3) to battery (+) terminal, and terminal (1) to battery
(–) terminal, respectively.
(3) Connecting and disconnecting the jumper wire on the
battery (–) terminal end, check for continuity across
terminal (2) and terminal (5), and across terminal (4) and
terminal (5), of fuel pump relay No.2.

12. FUEL PUMP RESISTOR CHECK
(1) Disconnect the fuel pump resistor connector.
(2) Measure resistance across the terminals.
Standard value: 0.6 – 0.9 Ω
(3) If the measurement falls outside the specified range,
replace the fuel pump resistor.

ENGINE COOLING – Radiator14-8
REMOVAL SERVICE POINTS
ARADIATOR UPPER HOSE / RADIATOR LOWER
HOSE DISCONNECTION
After making mating marks on the radiator hose and the hose
clamp, disconnect the radiator hose.
INSTALLATION SERVICE POINT
ARADIATOR LOWER HOSE / RADIATOR UPPER
HOSE CONNECTION
(1) Insert each hose as far as the projection of the water
inlet or outlet fitting.
(2) Align the mating marks on the radiator hose and hose
clamp, and then connect the radiator hose.
Caution
Fit the clamp on the hose at the same position as
before.
INSPECTION
1. RADIATOR FAN MOTOR CHECK
Apply the battery voltage across connector terminals 1 and
2, and terminals 3 and 4, of the radiator fan motor and check,
at that time, that the radiator fan turns.

(3) If the boost pressure is lower than the standard value,
check for following which are probably the cause:
Wastegate actuator inoperative
Boost pressure leak
Turbocharger defective
(4) If the boost pressure is higher than the standard value,
boost pressure control is probably faulty. Make the
following checks:
Wastegate actuator inoperative
Wastegate valve inoperative
Wastegate actuator rubber hose disconnected or
cracked
2. BOOST PRESSURE CONTROL SYSTEM
CHECK
(1) Disconnect the hose (black) from the wastegate solenoid
valve and connect a three-way joint between the hose
and solenoid valve.
(2) Connect a hand vacuum pump to the three-way joint.
(3) Disconnect the hose (black) from the intake pipe nipple
connected to the turbocharger compressor housing and
fit a blank plug to this nipple.
(4) Disconnect the negative cable from the battery, keep it
disconnected for 10 sec. or more, and then reconnect
it back again.
(5) Block and unblock the end of the vacuum hose (black)
with a finger to apply vacuum and check for the vacuum
condition.

NOTE
If the vacuum condition is faulty, the wastegate actuator,

3. WASTEGATE ACTUATOR CHECK
(1) Connect a hand pump (pressure type) to the nipple.
(2) Gradually increase the pressure being applied to check
for the pressure at which the wastegate actuator rod starts
moving (approx. 1 mm stroke).
Standard value: Approx. 100 kPa {1.02 kg/cm
2}
Caution
Do not apply a pressure more than 120 kPa {1.23
kg/cm
2} to prevent the diaphragm from being
damaged.
(3) If the pressure drastically deviates from the standard
value, check the actuator or wastegate valve and, if
necessary, replace the actuator or turbocharger assembly.
4. WASTEGATE SOLENOID VALVE CHECK
4-1 OPERATION CHECK
(1) Connect a hand vacuum pump to nipple A of the solenoid
valve.
(2) Using jumper wires, connect the solenoid valve terminal
to battery terminals.
(3) Disconnecting and reconnecting the jumper wire on the
(–) terminal side, apply vacuum to check for airtightness.

4-2 COIL RESISTANCE CHECK
Measure the resistance across solenoid valve terminals.
Standard value: 62 – 74 Ω (at 20
C)
5. AIR BYPASS VALVE CHECK
(1) Remove the air bypass valve.
(2) Connect a hand vacuum pump to the air bypass valve
nipple.
(3) Apply a vacuum of approx. 45 kPa {340 mmHg} and
check that the valve is airtight.
(4) Increase the vacuum and check for valve operation.

6. SECONDARY AIR CONTROL SYSTEM
CHECK
(1) Start the engine and let it run at idle speed.
(2) Short-circuit the no. 6 terminal of the engine ECU
connector using a jumper wire and check at this time
that the secondary air valve lifts.
At this time, the engine ECU connector should be
connected.
7. SECONDARY AIR CONTROL SOLENOID
VALVE CHECK
7-1 OPERATION CHECK
(1) Disconnect the vacuum hose (white stripe, yellow stripe)
from the solenoid valve.
(2) Disconnect the harness connector.
(3) Connect a hand vacuum pump to nipple A of the solenoid
valve.
(4) Using jumper wires, connect the solenoid valve terminal
to battery terminals.
(5) Disconnecting and reconnecting the jumper wire on the
(–) terminal side, apply vacuum to check for airtightness.
