System DescriptionNKS003AI
AUDIO SYSTEM
Refer to Owner's Manual for audio system operating instructions.
Power is supplied at all times
through 15A fuse (No. 32, located in the fuse and fusible link block)
to audio unit terminal 6
to A/C and AV switch terminal 1
to display control unit terminal 1
to woofer terminal 1
to satellite radio tuner terminal 12 (With satellite radio) and
to option connector–2 for satellite radio tuner terminal 12 (Without satellite radio),
through 20A fuse [No.17, located in the fuse block (J/B)]
to BOSE speaker amp. terminal 1.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 6, located in the fuse block (J/B)]
to audio unit terminal 10
to A/C and AV switch terminal 2
to display control unit terminal 10
to satellite radio tuner terminal 16 (With satellite radio) and
to option connector–2 for satellite radio tuner terminal 11 (Without satellite radio).
Ground is supplied through the case of the audio unit.
Ground is also supplied
to BOSE speaker amp. terminal 17
to woofer terminal 2
to satellite radio tuner terminal 15 (With satellite radio) and
to option connector–2 for satellite radio receiver terminal 10 (Without satellite radio)
through body ground B203 and B210,
to A/C and AV switch terminal 5
to display control unit terminals 3,13 and
to display terminal 1
through body ground M35, M45 and M85.
Audio unit, A/C and audio controller are connected by FPC (Flexible Print Circuit).
A/C and audio controller integrates A/C switches and audio switches.
When A/C and audio controller is pressed to audio switch, it sends audio signal to audio unit. Then audio sig-
nals are supplied
through audio unit terminals 1, 2, 3, 4, 13, 14, 15, and 16
to BOSE speaker amp. terminals 23, 24, 25, 26, 27, 28, 29, and 30.
Audio signals are amplified by the BOSE speaker amp.
The amplified audio signals are supplied
through BOSE speaker amp. terminals 2, 3, 4, 9,10,11,12, 13, 14, 15, 16, 18, 19 and 20
to terminals 1 and 2 of front door speaker LH and RH
to terminals 1 and 2 of rear door speaker LH and RH
to terminals 1 and 2 of tweeter LH and RH
to terminals 1 and 2 of instrument speaker LH, RH, and CENTER, and
to terminals 7 and 8 of woofer.
When one of audio steering wheel switch is pressed to ON (With telephone system), mode ON (Without
telephone system), seek up, or volume up, resistance in steering switch circuit changes depending on which
button is pressed.

BCM (BODY CONTROL MODULE)
Revision: 2006 July 2007 FX35/FX45
BCM STATUS CONTROL
BCM changes its status depending on the operation status in order to save power consumption.
1. CAN communication status
With ignition switch ON, CAN communicates with other control units normally.
Control by BCM is being operated properly.
When ignition switch is OFF, switching to sleep mode is possible.
Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.
2. Sleep transient status
This status shuts down CAN communication when ignition switch is turned OFF.
It transmits sleep request signal to IPDM E/R and combination meter.
2 seconds after CAN communication of all control units stops, sleep transient status is switched to CAN
communication inactive status.
3. CAN communication inactive status
With ignition switch OFF, CAN communication is not active.
With ignition switch OFF, control performed only by BCM is active.
3 seconds after CAN communication of all control units stops, CAN communication inactive status is
switched to sleep status.
4. Sleep status
BCM is activated with low power mode.
CAN communication is not active.
When CAN communication operation is detected, it switches to CAN communication status.
When a state of the following switches changes, it switches to CAN communication state.
–Key switch
–Hazard switch
–Door lock/unlock switch
–Front door switch (driver side, passenger side)
–Rear door switch (LH, RH)
–Back door opener switch
–Combination switch (passing, lighting switch 1ST position, front fog lamp)
–Key fob (lock/unlock signal)
–Key cylinder switch
When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.
Operation mode of combination switch reading function is changed.

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 BL-11, "
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.
