After connecting the airbag connectors, confirm
proper system operation; Turn the ignition switch ON

)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.

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'

NOTE (With keyless entry systeml:
. It the doors unlock or lock with the transmitter, but the LED on the transmitter does not come on, the LED is faulty;
replace the transmitter'
. when vou unlock the doors with the transmitter, the ceiling light (middle position) comes on for 30 seconds. (However,
if the audio unit is not installed, the light does not come on )
. lf any door is open, you cannot lock or unlockthe doors with the transmitter'
. The horn sounds only the first time you press a transmitter button. (Pressing repeatedly does not activate the horn
again.)
o lf vou unlocked the doors with the transmitter, but do not open any of the doors within 30 seconds, the doors relock
automatically.
. The doors do not lock or unlock with the transmitter if the ignition key is inserted in the ignition switch
. lf you press the PANIC button for more than two seconds, the horn sounds for about 30 seconds, and the transm'fer
LED comes on. (The panic mode will not be activated iJ the ignition key is in the ignition switch ) The panic mode is
cancelled by pressing any of the transmitter buttons'
o After replacing the transmitter battery, press the lock and unlock buttons five or six times to activate the transmitter'
