AUTOMATIC SPEED CONTROL DEVICE (A.S.C.D.)
- Trouble-shooting (Cont'd)
AIT model only
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.
