)Actuator Test
't.Disconnect the actuator cable from the actuator rod
and the 4P connector.
Connect battery power to the No 4 terminal and
ground to the No. 1, No. 2 and No. 3 terminals.
Connect a vacuum pump to the vacuum hose Then
apply vacuum to the actuator.

5. With voltage and vacuum still applied, try to pull the
actuator rod out by hand. You should not be able to
oull it out. ll you can, it is defective

Disconnect ground from the No.3 terminal. The actu-
ator rod should return lf it does not return, but the
vent hose and filter are not plugged, the solenoid
valve assembly is defective.
Repeat steps 2 through 5, and disconnect ground
from the No. 1 terminal. The actuator rod should
return. lI it does not return, but the vent hose and
filter are not plugged. the solenoid valve assembly
is defective.
It you replace the solenoid valve assembly, be sure
to use new O-rings on each solenoid.
Disconnect power and ground from the 4P connector.
Disconnect the vent hose from the actuator. Connect
a vacuum pump to the actuator vent hose port, and
apply vacuum. The actuator rod should pull in com-
pletely. lf not, the vacuum valve is stuck open.
Replace the actuator'

How To Use This Manual
Symbols
Ground - "G"
This symbol means the end ol
the wire is attached (grounded) Ito the car frame or to a metal I
part connected to the frame. \i oro,|
-t'
Each wire ground (G) it --/
numbered for reference.

Switches
These switches move
together; the broken straight
line between them means the,
are mechanically connected.
Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted. all switches are shown
in their normal (rest) position,
with power off.
This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car frame or to a metal
part connected to the frame.
This symbol represents
the bus inside a ground
connector. The dots I
i:l*,':1,'^:*,:"

r"L I I I
terminals connect to.
The ground symbol (large dot)
is the connection between the
bus and metal (grounded) part
of the car.
Terminals - "T"
ffi
ffi
Solid-state
Fuses
This means power is supplied
when the ignition switch is in ON (ll).
Current rating
Diodes
A rectifier diode works like a one
way valve. lt allows current to
llow only in the direction of the
arrow.
A Zener diode blocks reverse
current at normal voltages just like
a rectifier diode. At high voltages.
however, a Zener diode allows
current to f low in reverse
oo
Each "T" lerminal (ring type)
is numbered for reference and
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interference) shielding
around a wire. The
shielding is always
connected to ground.
