- Aiming Adjustment
When performing headlamp aiming adjustment, use
ail aiming machine, aiming wall screen or headlamp
tester For operating instructions of any airner, it
should be in good repair, calibrated and used ac-
cording to respective operation manuals supplied
with the unit
If any aimer is not available, aiming adjustment can
be done
as follows
For details, refer to the regulations in your own
country.
CAUTION:
a Keep all tires inflated to correct pressures.
b. Place vehicle and tester on
one and same flat
surface.
c See that there is no load in vehicle (coolant, en-
gine oil filled up to correct level and full fuel
tank) other than
the driver (or equivalent
weight placed in driver's position).

- Boost Sensor Check
1 Connect vacuum pump gauge to boost sensor
vacuum hose
2 Disconnect harness connector from boost
sensor and connect battery and voltmeter
as
shown

AUDIO AND POWER ANTENNA
Power Antenna Motor Check
1 Disconnect, at connector, harness between
power antenna unit and antenna timer.
2 Apply 12-volt battery voltage across @ and
@ to make Sure antenna rod extends and
retracts
3. Connect a voltmeter across terminal 0 and
ground terminal
of battery.
4 Check to determine if voltmeter varies between
0 and 12 volts (approx ) in relation to move-
ment
of antenna rod when 12-volt battery
voltage
IS applied across @ and @
If above test results are not satisfactory, re-
place antenna
motor.

CAUTION:
Do
not attempt to remove valves from actuator.
2 Connect battery (approx 12V) to harness
connector
of actuator as shown below, and
apply vacuum to actuator
If diaphragm moves smoothly, actuator IS O.K.
CAUTION.
When checking actuator by applying vacuum, do
not apply engine vacuum directly
as it IS too strong
to check actuator properly.
