HEADLAMP - XENON TYPE -PFP:26010
Component Parts and Harness Connector LocationAKS007M9
System DescriptionAKS007MA
Control of the headlamp system operation is dependent upon the position of the combination switch (lighting
switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input
signal requesting the headlamps (and tail lamps) illuminate. This input signal is communicated to the IPDM E/
R (intelligent power distribution module engine room) across the CAN communication lines. The central pro-
cessing unit of the IPDM E/R controls the headlamp high and headlamp low relay coils. These relays, when
energized, direct power to the respective headlamps, which then illuminate.
If voltage is applied to a high beam solenoid, the bulb shade will move, even a xenon head lamp bulb comes
out, and a high beam and a low beam are changed.

CAUTION:AKS007MT

Installation or removal of the connector must be done with the lighting switch OFF.

When the lamp is illuminated (when the lighting switch is ON), do not touch the harness, HID control unit,
inside of the lamp, or the lamp metal parts.

To check illumination, temporarily install lamp in the vehicle. Be sure to connect power at the vehicle-side
connector.

If the error can be traced directly to the electrical system, first check for items such as burned-out fuses
and fusible links, broken wires or loose connectors, pulled-out terminals, and improper connections.

Do not work with wet hands.

Using a tester for HID control unit circuit trouble diagnosis is prohibited.

Disassembling the HID control unit or harnesses (bulb socket harness, ECM harness) is prohibited.

Immediately after illumination, the light intensity and color will fluctuate, but there is nothing wrong.

When the bulb has reached the end of its lifetime, the brightness may drop significantly, it may flash
repeatedly, or the light may turn a reddish color.

Fuse AKS007VW

If fuse is blown, be sure to eliminate cause of incident before
installing new fuse.

Use fuse of specified rating. Never use fuse of more than speci-
fied rating.

Do not partially install fuse; always insert it into fuse holder prop-
erly.

Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible LinkAKS007VX
A melted fusible link can be detected either by visual inspection or by
feeling with finger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION:

If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted.
In such a case, carefully check and eliminate cause of inci-
dent.

Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl
or rubber parts.
Circuit Breaker AKS007VY
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

HARNESS CONNECTOR (SLIDE-LOCKING TYPE)

A new style slide-locking type connector is used on certain systems and components, especially those
related to OBD.

The slide-locking type connectors help prevent incomplete locking and accidental looseness or discon-
nection.

The slide-locking type connectors are disconnected by pushing or pulling the slider. Refer to the illustra-
tion below.
CAUTION:

Do not pull the harness or wires when disconnecting the connector.

Be careful not to damage the connector support bracket when disconnecting the connector.

INSTALLATION
1. Paying attention to following items, install in the reverse order of removal.
a. Install the propeller shaft onto the rear final drive companion
flange while aligning the matching marks that are marked during
removal.
b. Adjust position of the bearing cushion so as not to apply thrust
play to the center bearing insulator.
c. Position the bearing cushion overlap as shown in the figure.
d. Install the center bearing bracket (upper) with its arrow mark fac-
ing forward.
e. Tighten the center bearing mounting bracket (upper) fixing nuts
to specified torque.
CAUTION:
Do not reuse the nuts. Always replace the nuts with a new
ones.
2. If companion flange has been removed, put new alignment
matching mark C on it. Then, reassemble using the following
procedure.
Perform these steps when either of final drive and propeller
shaft is replaced with a new one.
a. Erase original mark C from companion flange with suitable sol-
vent.
b. Measure companion flange vertical runout.
c. Determine the position where maximum runout is read on dial
gauge. Put mark (shown by C in figure) on flange perimeter cor-
responding to maximum runout position.

CHECKING FRONT WHEEL TURNING ANGLE

Check front wheel turning angle after the toe-in inspection.
Place front wheels on turning radius gauges and rear wheels on
stands so that vehicle can be level. Check the maximum inner
and outer wheel turning angles for LH and RH road wheels.

Start engine and run at idle, turn steering wheel all the way right
and left, measure the turning angle.

Any turning angles are not adjustable. If any of steering angles
are out of the specification, check if the following parts are wear
or damaged.
–Steering gear
–St ee rin g c o lum n
–Front suspension components
If found that they are worn or damaged, replace them with new ones respectively.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diag-
nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any
customer's comments; refer to RF-8, "
Diagnostic Worksheet" . This information is necessary to duplicate the
conditions that exist when the noise occurs.

The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).

If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer
is concerned about. This can be accomplished by test driving the vehicle with the customer.

After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.

Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping

Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.

Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing
clip or fastener/incorrect clearance.

Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.

Tick—(Like a clock second hand)
Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver
action or road conditions.

Thump—(Heavy, muffled knock noise)
Thump characteristics include softer knock/dead sound often brought on by activity.

Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.

Often the degree of acceptable noise level will vary depending upon the person. A noise that you may
judge as acceptable may be very irritating to the customer.

Weather conditions, especially humidity and temperature, may have a great effect on noise level.

REMOVAL
1. Remove the rear propeller shaft. Refer to PR-8, "REMOVAL" .
2. Put a matching mark on the end of the drive pinion correspond-
ing to the C position matching mark on the final drive companion
flange.
CAUTION:

For matching mark, use paint. Never damage drive pin-
ion.

The matching mark C on the final drive companion flange
indicates the maximum vertical runout position.
3. Using the drive pinion flange wrench, remove drive pinion lock
nut.
4. Remove the companion flange using the puller.
5. Remove front oil seal using the side bearing outer race puller,
INSTALLATION
1. Apply multi-purpose grease to sealing lips of oil seal. Press front
oil seal into carrier with tool.
NOTE:

When installing the oil seal, be careful not to get it inclined.

Discard the old oil seal. Always replace with new one.
