Precaution for Procedur e without Cowl Top CoverINFOID:0000000001612933
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
General PrecautionINFOID:0000000001325654
 Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any flam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or ot her enclosed area, be sure to prop-
erly ventilate the area before working with hazardous materials.
Do not smoke while working on the vehicle.
 Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
These operations should be done on a level surface.
 When removing a heavy component such as the engine or tran- saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
 Before starting repairs which do not require battery power: Turn off ignition switch.
Disconnect the negative battery terminal.
 If the battery terminals are disconnected, recorded memory of radio and each control unit is erased.
 Battery posts, terminals and related accessories contain lead and
lead compounds. Wash hands after handling.

Work FlowINFOID:0000000001327957
CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions thatexist when the noise occurs. Use the Diag-
nostic Worksheet during the interviewto document t he facts and conditions when the noise occurs and any
customer'scomments; refer to GW-9, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that existwhen the noise occurs.
 The customer may not be able to provide a detailed descriptionor the location of the noise. Attempt to obtain all the facts and conditionsthat exist w hen the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, be sure to diagnoseand repair the noise that the customer is
concerned about. This can be accomplishedby 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/fa st movement/broughton by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=l owerpitch noises/edge to surface=chirping
 Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/twisting witha rotational movement/pitch depen-
dent on materials/often brought on by activity.
 Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contac t/vibration orsimilar movement/loose parts/missing clip
or fastener/incorrect clearance.
 Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/some times repeating/oftenbrought on by driver action.
 Tick—(Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loosecomponents/can be caused by driver
action or road conditions.
 Thump—(Heavy, muffled knock noise) Thump characteristics include softer k nock/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 dependingupon the person. A noise that you may judge as acceptable may be very irritatingto the customer.
 Weather conditions, especially humidity and temper ature, may havea great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise isduplicated. Note any additional information on
the Diagnostic Worksheet regardingthe conditions or location of the noise. This information can be used to
duplicatethe same conditions when you confirm the repair.

System DescriptionINFOID:0000000001328266
Control of the headlamp system operation is dependent upon t he 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) through the CAN communication lines. The CPU (central
processing unit) located in the IPDM E/R contro ls 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.
OUTLINE
Power is supplied at all times
 to headlamp high relay, located in IPDM E/R
 to headlamp low relay, located in IPDM E/R and
 to ignition relay, located in IPDM E/R, from battery direct,
 through 10A fuse (No. 71, located in IPDM E/R)
 to CPU located in IPDM E/R,
 through 15A fuse (No. 78, located in IPDM E/R)
 to CPU located in IPDM E/R,
 through 50A fusible link (letter M, located in fuse, fusible link and relay box)
 to BCM terminal 55,
 through 15A fuse [No. 22, located in fuse block (J/B)]
 to BCM terminal 42,
 through 10A fuse [No. 19, located in fuse block (J/B)]
 to combination meter terminal 8.
With ignition switch in ON or START position, power is supplied
 to ignition relay, located in IPDM E/R, from battery direct
 through 15A fuse [No. 1, located in fuse block (J/B)]
 to BCM terminal 38,
 through 10A fuse [No. 14, located in fuse block (J/B)]
