If specified voltage or continuity is not produced,
replace power unit.
- 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
3 Apply vacuum pressure to boost sensor by
vacuum pump gauge and measure voltages

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.

0 When A S C D is set while vehicle is operating
in
"0 D " range, 0 D will be cancelled and
shifting to
0 D cannot be made thereafter
0 While vehicle is being driven using AS C D in
"0 D "range, 0 D will not be cancelled even
if actual car speed is 6 kmlh (4 MPH) lower
than
set speed (Set speed cannot be main-
tained

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.
