Sunload Sensor CircuitAJS00156
COMPONENT DESCRIPTION
Sunload Sensor
The sunload sensor is located on the passenger side front defroster
grille. It detects sunload entering through windshield by means of a
photo diode. The sensor converts the sunload into a current value
which is then input into the unified meter and A/C amp.
SUNLOAD INPUT PROCESS
The unified meter and A/C amp. also includes a processing circuit which averages the variations in detected
sunload over a period of time. This prevents drastic swings in the ATC system operation due to small or quick
variations in detected sunload.
For example, consider driving along a road bordered by an occasional group of large trees. The sunload
detected by the sunload sensor will vary whenever the trees obstruct the sunlight. The processing circuit aver-
ages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the ATC system operation. On the other hand, shortly
after entering a long tunnel, the system will recognize the change in sunload, and the system will react accord-
ingly.
DIAGNOSTIC PROCEDURE FOR SUNLOAD SENSOR
SYMPTOM: Sunload sensor circuit is open or shorted. (25 or −25 is
indicated on unified meter and A/C amp. as a result of performing
Self-diagnosis STEP-2.)
1. CHECK VOLTAGE BETWEEN SUNLOAD SENSOR AND GROUND
1. Disconnect sunload sensor connector.
2. Turn ignition switch ON.
3. Check voltage between sunload sensor harness connector M87
terminal 1 (LG) and ground.
OK or NG
OK >> GO TO 2.
NG >> GO TO 4.

Intake Sensor CircuitAJS00157
COMPONENT DESCRIPTION
Intake Sensor
The intake sensor is located on the heater & cooling unit. It converts
temperature of air after it passes through the evaporator into a resis-
tance value which is then input to the unified meter and A/C amp.
DIAGNOSTIC PROCEDURE FOR INTAKE SENSOR
SYMPTOM: Intake sensor circuit is open or shorted. (24 or −24 is
indicated on unified meter and A/C amp. as a result of performing
Self-diagnosis STEP-2.)
1. CHECK VOLTAGE BETWEEN INTAKE SENSOR AND GROUND
1. Disconnect intake sensor connector.
2. Turn ignition switch ON.
3. Check voltage between intake sensor harness connector M254
terminal 2 (R) and ground.
OK or NG
OK >> GO TO 2.
NG >> GO TO 4.
2. CHECK CIRCUIT CONTINUITY BETWEEN INTAKE SENSOR AND UNIFIED METER AND A/C AMP.

2. Disconnect unified meter and A/C amp. connector.
3. Check continuity between intake sensor harness connector
M254 terminal 1 (W) and unified meter and A/C amp. harness
connector M57 terminal 49 (W/G).
OK or NG

BASE 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 and

to display control unit terminal 1 (with navigation system) or display unit terminal 1 (without navigation sys-
tem).
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 and

to display control unit terminal 10 (with navigation system) or display unit terminal 2 (without navigation
system).
Ground is supplied through the case of the audio unit.
Ground is also supplied

to A/C and AV switch terminal 5

to display control unit terminal 3 and 13 (with navigation system)

to display terminal 1 (with navigation system)

to display unit terminal 6 and 15 (without navigation system)

through body ground M35, M45 and M85

to option connector for satellite radio receiver terminal 10

through body ground B210 and B203.
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 pushed to audio switch, it sends audio signal to audio unit.
Then audio signals are supplied

through audio unit terminals 1, 2, 3, 4, 13, 14, 15, and 16

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 instrument speaker LH and RH.
When one of audio steering wheel switch is pushed to volume up, seek up, or mode ON, resistance in steering
switch circuit changes depending on which button is pushed.
When one of audio steering wheel switch is pushed to volume down, seek down, or power ON, resistance in
audio steering wheel switch circuit changes depending on which button is pushed.
BOSE 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 woofer terminal 1

to A/C and AV switch terminal 1 and

to display control unit terminal 1 (with navigation system) or display unit terminal 1 (without navigation sys-
tem),

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
