REMOVAL

1.

Drain engine coolant from radiator drain plug at the bottom of radiator, and from water drain plug at the
front of cylinder block. Refer to 

CO-11, "Draining"

 and 

EM-90, "Setting"

.

CAUTION:

• Perform this step when the engine is cold.
• Never spill engine coolant on drive belt.

2.

Remove reservoir tank of radiator, and move it aside. Refer to 

CO-16, "Exploded View"

.

3.

Remove intake valve timing control solenoid valve (bank 2). Refer to

EM-57, "Exploded View"

.

4.

Disconnect radiator hose (lower) from water inlet and thermostat assembly.

5.

Remove water inlet and thermostat assembly (1).

CAUTION:

Never disassemble water inlet and thermostat assembly.
Replace them as a unit, if necessary.

INSTALLATION

Note the following, and install in the reverse order of removal.
• Be careful not to spill engine coolant over engine room. Use rag to absorb engine coolant.

INSPECTION AFTER REMOVAL

1.

Check valve seating condition at ordinary room temperatures. It should seat tightly.

2.

Check valve operation.

• If the malfunctioning condition, when valve seating at ordinary

room temperature, or measured values are out of the standard,
replace water inlet and thermostat assembly.

INSPECTION AFTER INSTALLATION

• Check for leakage of engine coolant using the radiator cap tester adapter (commercial service tool) and the

radiator cap tester (commercial service tool). Refer to 

CO-11, "Inspection"

.

• Start and warm up the engine. Visually check that there is no leakage of engine coolant.

Work Flow

INFOID:0000000006260838

DETAILED FLOW

1.

OBTAIN INFORMATION ABOUT SYMPTOM

Interview the customer to obtain the malfunction information (conditions and environment when the malfunc-
tion occurred) as much as possible when the customer brings the vehicle in.

>> GO TO 2.

2.

CHECK DTC

Perform self diagnosis with CONSULT-III
Is any DTC detected?

YES

>> Refer to 

DEF-60, "DTC Index"

.

NO

>> GO TO 3.

3.

REPRODUCE THE MALFUNCTION INFORMATION

Check the malfunction on the vehicle that the customer describes.
Inspect the relation of the symptoms and the condition when the symptoms occur.

>> GO TO 4.

4.

IDENTIFY THE MALFUNCTIONING SYSTEM WITH “SYMPTOM DIAGNOSIS”

Use “Symptom diagnosis” from the symptom inspection result in step 3. Then identify where to start perform-
ing the diagnosis based on possible causes and symptoms.

>> GO TO 5.

5.

IDENTIFY MALFUNCTIONING PARTS WITH “COMPONENT DIAGNOSIS”

Perform the diagnosis with “Component diagnosis” of the applicable system.

>> GO TO 6.

6.

REPAIR OR REPLACE THE MALFUNCTIONING PARTS

Repair or replace the specified malfunctioning parts.

>> GO TO 7.

7.

FINAL CHECK

Check that malfunctions are not reproduced when obtaining the malfunction information from the customer,
referring to the symptom inspection result in step 3.
Are all malfunctions corrected?

YES

>> INSPECTION END

NO

>> GO TO 4.

WITH BOSE SYSTEM : System Description

INFOID:0000000006260840

Operation Description

• Turn rear window defogger switch ON when the ignition switch is turned ON. Then multifunction switch (rear

window defogger switch) transmits rear window defogger switch signal to AV control unit via AV communica-
tion. AV control unit transmits rear window defogger switch signal to BCM via CAN communication.

• BCM turns rear window defogger relay ON and transmits rear window defogger control signal to IPDM E/R

via CAN communication when rear window defogger switch signal is received.

• Rear window defogger and door mirror defogger (with door mirror defogger) are supplied with power and

operate when rear window defogger relay turns ON.

• IPDM E/R transmits rear window defogger control signal to AV control unit via CAN communication. 
• AV control unit transmit rear defogger indicator signal to multifunction switch (rear window defogger switch)

via AV communication. then rear window defogger indicator is illuminated.

Timer function

• BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch

is turned ON. It makes rear window defogger and door mirror defogger (with door mirror defogger) operate.

• Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns

rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch
is turned OFF.

POWER SUPPLY AND GROUND CIRCUIT

Diagnosis Procedure

INFOID:0000000006260849

1.

CHECK FUSE AND FUSIBLE LINK

Check that the following fuse and fusible link are not blown.

Is the fuse blown?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is

blown.

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect BCM connectors.

3.

Check voltage between BCM harness connector and ground.

Is the measurement value normal?

YES

>> GO TO 3.

NO

>> Repair or replace harness or connector.

3.

CHECK GROUND CIRCUIT

Check continuity between BCM harness connector and ground.

Does continuity exist?

YES

>> INSPECTION END

NO

>> Repair or replace harness or connector.

Terminal No.
