INPUT SIGNAL

When using the scan tool (MUT) or voltmeter
Using the scan tool or voltmeter, check whether or not the
input signals from each switch are being input to the ETACS
unit.
(1) Connect the scan tool to the data link connector located
at the right side of the junction block or connect the voltme-
ter between the ETACS terminal and the ground terminal.
(2) Check if the buzzer of the scan tool sounds or the needleof the voltmeter moves when each switch is operated.
If the buzzer sounds or the needle moves, the input signalsare being input to the ETACS unit, so that switch can
be considered to be functioning normally. If not, the switch
or switch input circuit is faulty. Check the switch and the
switch input circuit.

When using the scan tool (MUT-II)
(1) Connect the scan tool to the data link connector. When
connecting the scan tool to a vehicle up to 1993 models,
use the adapter harness supplied together.
Caution
Turn off the ignition switch beforehand whenever thescan tool is connected or disconnected.
(2) If the scan tool makes a peep sound when each switchis operation (turned ON/OFF), the input signal to ECU
is normally sent from the switch circuit system.
When using the voltmeter
(1)Connect a voltmeter to the ETACS terminal and the ground
terminal of the data link connector using the special tool.
(2) If the voltmeter pointer deflects once when each switchis operated (turned ON/OFF), the input signal to ECU
is normally sent from the switch circuit system.

l
When the ignition switch is switched to the
ON position, battery voltage is applied (viathe multipurpose fuse (11) and hazard
switch) to the turn-signal and hazard flasher
unit.l
When the turn-signal switch is switched to
the LH position,
Trl (within the flasher unit)
is switched ON and OFF repeatedly.
Then the contacts of the relay 1 (also within
the flasher unit) repeatedly switch from ON
to OFF, causing the turn-signal lights and
turn-signal indicator light LH to flash.l
When the turn-signal switch is switched to
the RH position, Tr2 (within the flasher unit)
is switched ON and OFF repeatedly.Then the contacts of relay 2 (also within
the flasher unit) repeatedly switch from ON
to OFF, causing the turn-signal lights and
turn-signal indicator light RH to flash.2. If one of the bulbs is burned out
lIf the LH (or RH) turn-signal light bulb is
burned-out, the resistance of the turn-signalcircuit as a whole increases, resulting in
Lshorter ON and OFF intervals of the LHTrl (or RH Tr2) and a higher flashing rateof the LH lights (or RH lights).CHASSIS ELECTRICAL

TURN-SIGNAL LIGHT AND HAZARD
L
LIGHT
OPERATION
lWhen the hazard-warning switch is switch-
ed to the “ON” position, the relay contactof the turn signal and hazard flasher unit
is switched ON and OFF repeatedly, in thesame manner as for the operation of the
turn-signal lights, and the left and right turn-
signal lights and turn-signal indicator lights
simultaneously flash repeatedly.
NOTE
(1) The number of flashes of the hazard-warn-
ing lights does not change if there is dam-
aged or disconnected wiring of one light.
(2)The light automatic shut-OFF system is valid
for the illumination light of the hazard switch.(Refer to
P.54-37.)
TROUBLESHOOTING HINTS
1.The turn-signal lights and hazard-warning lightsdo not operate at all.
l Check the hazard switch contact (power
supply side).l Check the turn-signal and hazard flasher
unit.2. All turn-signal lights at the left (or right) side
do not function.
(1) The hazard-warning lights function normal-
ly-lCheck the hazard switch contact (turn-
signal side).l Check the turn-signal switch.
3.The number of flashes of the turn-signal lights
is excessive.l Check the bulbs.
4. The hazard-warning lights do not function.
(1) The turn-signal lights function normally.l
Check the hazard switch contact (haz-
ard-warning light side).
NOTE
For the troubleshooting hints of the automatic lightshut-OFF system, refer to
P.54-37.

LUMINOUS INTENSITY MEASUREMENT
Measure the luminous intensity of headlights with a photo-me-ter in accordance with the instruction manual prepared by
the manufacturer of the photometer and make sure that the
luminous intensity is within the following limit.Limit: 20,000 cd or more
NOTE
(1) When measuring the luminous intensity of headlight, keepthe engine at 2,000 rpm and have the battery charged.
(2) If there are specific regulations for luminous intensity ofheadlights in the region where the vehicle is operated,
make sure that the intensity conforms to the requirements
of such regulations.
FOG LIGHT AIMING
1.Place vehicle on a known level floor 7.6 m (25 feet) from
aiming screen or light colored wall.
2. Use adjusting screw to adjust the top end of high intensity
zone to dimension A.
BULB REPLACEMENT
1. Disconnect the connector.
2. Turn the bulb socket counterclockwise to pull it out.
Caution
Do not touch the surface of the headlight bulb with handsor dirty gloves. If the surface dies become dirty, clean
it with alcohol or thinner, and let it dry thoroughly before
installing.

To center the clock spring, line up the “NEUTRAL” markof the clock spring with the mating mark.
CautionIf the clock spring’s mating mark is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal op-eration of the SRS and possibly leading to serious
injury to the vehicle’s driver.
INSPECTION
(1) Remove the knee protector and the column cover. (Refer
(2)
to GROUP 52A - Instrument Panel.)
Disconnect the column switch left connector (16 terminals)
and check the continuity between the terminals for each
switch.
LIGHTING SWITCH CHECK
Operate the switch and check the continuity between the termi-
nals.

About multipath noise and fading noise
Because the frequency of FM waves is extreme-
ly high, it is highly susceptible to effects from
geological formations and buildings. These ef-
fects disrupt the broadcast signal and obstruct
‘reception in several ways.l Multipath noise
This describes the echo that occurs when the
broadcast signal is reflected by a large obstruc-
tion and enters the receiver with a slight time
delay relative to the direct signal (repetitious
buzzing).l Fading noise
This is a buzzing noise that occurs when the
broadcast beam is disrupted by obstructing ob-
jects and the signal strength fluctuates intricately
within a narrow range.
