7. Connect a tachometer or the MUT-II/III (Refer to
GROUP 11A − On-vehicle Service − Idle speed
check <4G1> P.11A-11 or GROUP 11C −
On-vehicle Service − Idle speed check <4G6>
P.11C-11).
8. Leave the hood open.
9. Check that the reading on the voltmeter is equal
to the battery voltage.
NOTE: If the voltage is 0 V, the cause is probably
an open circuit in the wire or fusible link between
the alternator "B" terminal and the battery (+)
terminal.
10.Turn the light switch on to turn on headlamps and
then start the engine.
11.Immediately after setting the headlamps to high
beam and turning the heater blower switch to the
high revolution position, increase the engine
speed to 2,500 r/min and read the maximum
current output value displayed on the ammeter.
Limit: 70 % of normal current outputNOTE: .
•For the nominal current output, refer to the
Alternator Specifications.
•Because the current from the battery will soon
drop after the engine is started, the above step
should be carried out as quickly as possible in
order to obtain the maximum current output
value.
•The current output value will depend on the
electrical load and the temperature of the
alternator body.
•If the electrical load is small while testing, the
specified level of current may not be output
even though the alternator is normal. In such
cases, increase the electrical load by leaving
the headlamps turned on for some time to
discharge the battery or by using the lighting
system in another vehicle, and then test again.
•The specified level of current also may not be
output if the temperature of the alternator body
or the ambient temperature is too high. In such
cases, cool the alternator and then test again.
12.The reading on the ammeter should be above the
limit value. If the reading is below the limit value
and the alternator output wire is normal, remove
the alternator from the engine and check the
alternator.
13.Run the engine at idle after the test.
14.Turn the ignition switch to the "LOCK" (OFF)
position.
15.Remove the tachometer or the MUT-II/III.
16.Disconnect the negative battery cable.
17.Disconnect the ammeter and voltmeter.
18.Connect the negative battery cable.

TROUBLESHOOTING M1542000701281
Features the headlamp automatic shutdown function
to avoid battery drain when the headlamps are left
on. The main features are as follows:
•Extinguishes automatically in three minutes if the
ignition switch is turned off with the lighting switch
on.
•Extinguishes in one second if the driver's door is
opened within that 3-minute period.
•If the headlamps are turned on with the ignition
switch off, the headlamps and tail lamps will
extinguish in three minutes after the driver's door
is opened or closed.
The headlamps are controlled by the Smart Wiring
System (SWS). For troubleshooting, refer to
respective Groups below.
•Not using SWS monitor: GROUP 54B, SWS
Troubleshooting P.54B-38.
•Using SWS monitor: GROUP 54C, SWS

HEADLAMP AIMING
M1542000900538
PRE-AIMING INSTRUCTIONS
1. Inspect for badly rusted or faulty headlamp
assemblies.
2. These conditions must be corrected before a
satisfactory adjustment can be made.
3. Inspect tyre inflation, and adjust if it is necessary.
4. If the fuel tank is not full, place a weight in luggage
room of the vehicle to simulate weight of a full
tank (0.8 kg per litre).
5. There should be no other load in the vehicle other
than driver or substituted weight of approximately
75 kg placed in driver's position.
6. Thoroughly clean the headlamp lenses.7. Place the vehicle on a level floor, perpendicular to
a flat screen 10 m away from the bulb
centre-marks on the headlamp lens.
8. Rock vehicle sideways to allow vehicle to assume
its normal position.
9. Bounce the front suspension through three (3)
oscillations by applying the body weight to hood
or bumper.
10.Four lines of adhesive tape (or equivalent
markings) are required on screen or wall:
(1) Position a vertical tape or mark so that it is
aligned with the vehicle centre line.
(2) Measure the distance from the centre-marks
on the headlamp lens to the floor. Transfer the
measurement to the screen. Horizontal tape or
mark on the screen is for reference of vertical
adjustment. Item Standard value Limit

HEADLAMP ADJUSTMENT
CAUTION
•Do not cover a headlamp for more than three
minutes to prevent the plastic headlamp lens
deformation.
•When adjusting one headlamp beam, make
sure that another headlamp is off by
disconnecting the connector from it. When
reconnecting the connector, make sure that
the headlamp beam is not disturbed
accidentally.
1. The low-beam headlamp should project on the
screen upper edge of the beam (cut-off).
2. If not the case, turn the adjusting screws to
achieve the specified low-beam cut-off location on
the aiming screen.Standard value:
(Vertical direction) 0.69° below horizontal (H)
(Horizontal direction) Position at which the

LUMINOUS INTENSITY MEASUREMENTM1542001000464
1. Set the headlamps to high-beam.
2. Using a photometer, and following its
manufacturer's instruction manual, measure the
headlamp centre intensity and check to be sure
that the limit value is satisfied.
Limit: 30,000 cd or more {When a screen is
set 25m ahead of the vehicle}
NOTE: When measuring the intensity, maintain an
engine speed of 2,000 r/min., with the battery fully
charged.
There may be special local regulations pertaining to
headlamp intensity. Be sure to make any
adjustments necessary to satisfy such regulations.
If an illuminometer is used to make the
measurements, convert its values to photometer
values by using the following formula.
I =E x r
2:
•I = intensity (cd)
•E = illumination (lux)
•r = distance (m) from headlamps to illuminometer
