INSPECTION
FUNCTION AND OPERATION PRICIPLE
Variable Intake manifold Solenoid (VIS) valves are installed on surge tank (VIS Valve #1) and intake manifold (VIS
Valve #2). These VIS valve #1 and #2 control vacuum modulators which activate valves in surge tank and intake
manifold. These valves are opened or closed by PCM according to engine condition (Refer to below table).

SERVICE ADJUSTMENT PROCEDURE
Automatic transaxle fluid
INSPECTION 1. Drive the vehicle until the fluid reaches normal operating temperature [70~80°C].
2. Place the vehicle on a level surface.
3. Move the selector lever through all gear positions. This will fill the torque converter and the hudraulic system with
fluid and move the selector lever to the "N" (Neutral) or "P"(Park) position.
4. Before removing the oil level gauge, wipe all contaminants from around the oil level gauge. Then take out the oil
level gauge and check the condition of the fluid.
If the fluid smells as if it is burning, it means that the fluid has been contaminated by fine particles from the
bushes and friction materials, a transaxle overhaul may be necessary.
5. Check that the fluid level is at the HOT mark on the oil level gauge. If the fluid level is low, add automatic transaxle
fluid until the level reaches the "HOT" mark.
Auto transaxle fluid:
DIAMOND ATF SP - III, SK ATF SP - III
Quantity : 8.5ℓ (9.0 US qt, 7.5 lmp.qt)
Low fluid level can cause a variety of a abnormal conditions because it allows the pump to take in air along
with fluid. Air trapped in the hydraulic system forms bubbles, which are compressable. Therefore, pressures
will be erratic, causing delayed shifting ,slipping clutches and brakes, etc. Improper filling can also raise fluid
level too high. When the transaxle has too much fluid, gears churn up foam and acuise the same conditions
which occur with low fluid level, resulting in accelerated deterioration of automatic transaxle fluid. In either
case, air bubbles can cause overheating, and fluid oxidation, which can interfere with normal valve, clutch, and
brake operation. Foaming can also result in fluid escaping from the transaxle vent where it may be mistaken
for a leak.
6. Insert the oil level gauge(A) securely.
When new, automatic transmission fluid should be red. The red dye is added so the assembly plant can
identify it as transmission fluid and distinguish it from engine oil or antifreeze. The red dye, which is not an
indicator of fluid quality, is not permanent. As the vehicle is driven the transmission fluid will begin to look
darker. The color may eventually appear light brown.
