RESERVOIR TANK CAP
RESERVOIR TANK CAP : InspectionINFOID:0000000006289661
 Check valve seat of reservoir tank cap.
- Check if valve seat (A) is swollen to the extent that the edge of the
metal plunger (B) cannot be seen when watching it vertically from
the top.
- Check if valve seat has no soil and damage.
 Pull negative-pressure valve to open it, and check that it close completely when released.
- Check that there is no dirt or dam age on the valve seat of reservoir
tank cap negative-pressure valve.
- Check that there are no unusualness in the opening and closing conditions of negative-pressure valve.
 Check reservoir tank cap relief pressure.
- When connecting reservoir tank cap to the radiator cap tester (commercial service tool) and the r adiator cap tester adapter (com-
mercial service tool) (A), apply engine coolant to the cap seal sur-
face.
 Replace reservoir tank cap if there is an unusualness related to the above three.
CAUTION:
When installing reservoir tank cap , thoroughly wipe out the water inlet filler neck to remove any waxy
residue or foreign material.

RADIATOR : InspectionINFOID:0000000006289662
Check radiator for mud or clogging. If neces sary, clean radiator as per the following:
 Be careful not to bend or damage radiator fins.
 When radiator is cleaned without removal, remove all surrounding parts such as radiator cooling fan shroud. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surfaces once per minute.

1.PERFORM SELF-DIAGNOSIS
Perform self-diagnosis of ADAS control unit and lane camera unit.
Is any DTC detected?
Except “C1B01”>>Perform diagnosis on the detected DTC and repair or replace the applicable item. Refer to
DAS-310, "
DTC Index" (ICC/ADAS) or DAS-316, "DTC Index" (LANE CAMERA).
“C1B01” or no DTC>>GO TO 2.
2.PREPARATION BEFORE CAMERA AIMING ADJUSTMENT
1. Perform pre-inspection for diagnosis. Refer to DAS-335, "
Inspection Procedure".
2. Adjust the tire pressure to the specified pressure value.
3. Maintain no-load in vehicle.
4. Check if coolant and engine oil are filled up to correct level and fuel tank is full.
5. Shift the selector lever to “P” position and release the parking brake.
6. Clean the windshield.
7. Completely clear off the instrument panel.
>> GO TO 3.
3. PREPARATION OF AIMING ADJUSTMENT JIG
Prepare the aiming adjustment jig according to the following procedure and the figure.
1. Print out the target mark attached in this service manual. Refer to DAS-343, "
Work Procedure (Target
Mark Sample)".
2. Stick a printed target mark on the board with a scotch tape or a piece of double-sided tape.
NOTE:
 Use the board that peripheral area of the ta rget is monochrome such as a white-board.
 Notice that the cross of the target is horizontal and vertical.

AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation.
 Oil pressure warning lamp
 Rear window defogger
 Front wiper (LO, HI)
 Parking lamp
 License plate lamp
 Tail lamp
 Side marker lamp
 Front fog lamp
 Headlamp (LO, HI)
 A/C compressor (magnet clutch)
Operation Procedure
CAUTION:
Never perform auto active test in the following conditions.
 Engine is running.
 CONSULT-III is connected.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper

1. When measuring voltage, wrap tin foil around the top of the neg- ative probe. Then press the foil against the wire with your finger.
2. Attach probe circuit tester (in Volt range) to middle portion of each filament.
3. If a filament is burned out, circuit tester registers 0 or battery voltage.
4. To locate burned out point, move probe to left and right along fil- ament. Test needle will swing abruptly when probe passes the
point.

Precautions For Xenon Headlamp ServiceINFOID:0000000006225830
WARNING:
Comply with the follow ing warnings to prevent any serious accident.
 Disconnect the battery cable (neg ative terminal) or the power supply fuse before installing, remov-
ing, or touching the xenon headlamp (bulb included). The xenon headlamp contains high-voltage
generated parts.
 Never work with wet hands.
 Check the xenon headlamp ON-OFF status after assem bling it to the vehicle. Never turn the xenon
headlamp ON in other conditions. Connect th e power supply to the vehicle-side connector.
(Turning it ON outside the lamp case m ay cause fire or visual impairments.)
 Never touch the bulb glass immediately afte r turning it OFF. It is extremely hot.
CAUTION:
Comply with the follow ing cautions to prevent an y error and malfunction.
 Install the xenon bulb securely. (I nsufficient bulb socket installation may melt the bulb, the connec-
tor, the housing, etc. by high-vol tage leakage or corona discharge.)
 Never perform HID circuit inspection with a tester.
 Never touch the xenon bulb glass with ha nds. Never put oil and grease on it.
 Dispose of the used xenon bulb after p acking it in thick vinyl without breaking it.
 Never wipe out dirt and cont amination with organic solven t (thinner, gasoline, etc.).
WorkINFOID:0000000006225831
 After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check their
operational.
 Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.
