CRUISE CONTROL SYSTEM 1 5
B.Check Switch
The check switch in the ACC checker is used to
check the actuator operation while the engine is
running. When the check switch is held on after
the engine is started, the engine speed increases
to approximately 2,000 to 3,000 rpm and is main-
tained at that level. When the check switch is
released, the engine speed decreases to idle
speed.
76G15X-073
C.Slide switch
Before using the check switch, first move the slide
switch to the "L" position.
Then use the check switch to increase the engine
rpm.
If the engine rpm stabilizes after increasing to
2,000—3,000 rpm, there is no problem. If there is
no increase at all, or only a slight increase, try again
after setting the slide switch to the "H" position.
If there is still no increase to 2,000—3,000 rpm,
adjust the free play of the actuator inner cable.

Preparation
1. ACC checker installation
Depress the lock hook of the harness connector.
Remove the connector from the ACC control unit
after the ignition switch and main switch are turned
off, and then connect the harness connector to the
ACC checker.
2. Checking the free play of the actuator inner
cable
Remove the clip and adjust the nut so that the ac-
tuator control cable play is as follows when the ca-
ble is pressed lightly.
Standard play: 1—3 mm (0.039—0.118 in)

16 OUTLINE
Safety Precautions
1. The R-12 liquid refrigerant is highly volatile. A drop
of it on the skin of your hand could result in local-
ized frostbite. When handling the refrigerant, be
sure to wear gloves.
2. If the refrigerant splashes into your eyes, wash
them with clean water immediately. It is standard
practice to wear goggles or glasses to protect your
eyes, and gloves to protect your hands.
3. The R-12 container is a highly pressurized vessel.
Never leave it in a hot place, and check to be sure
that the temperature where it is stored is below
52°C (126°F).
4. A halide leak detector is often used to check the
system for refrigerant leakage. Remember that
R-12, upon coming into contact with flame (this de-
tector burns like propane to produce a small flame),
produces phosgene, a toxic gas.

Refrigerant Container Service Valve
1. Before connecting the valve to the refrigerant con-
tainer, turn the handle fully counterclockwise.
2. Turn the disc counterclockwise until it reaches its
highest position.
3. Connect the center hose to the valve fitting. Turn
the disc fully clockwise by hand.
4. Turn the handle clockwise to make a hole in the
sealed tap.
5. Turn the handle fully counterclockwise to fill the
center hose with air. Do not open the high- and
low-pressure manual valves.
6. Loosen the center hose nut connected to the cen-
ter fitting of the manifold gauge.
Allow air to escape for a few seconds, then tight-
en the nut.

16 CONDENSER
CONDENSER
ON-VEHICLE INSPECTION
1. Check the condenser fins for blockage or damage.
If the fins are clogged, clean them with compressed air.
If the fins are bent, straighten them with a screwdriver or pair of pliers.
2. Check the condenser fittings for leakage.
Repair or replace, if necessary.
REMOVAL OF CONDENSER

2. Remove the front grille and the air seal cover.
3. Disconnect the discharge flexible hose from the condenser inlet fitting.
4. Disconnect the liquid line pipe from the condenser outlet fitting.
Note:
Plug the open fittings immediately to keep moisture out of the system.
6. Remove the condenser.
