INSPECTION PROCEDURE
Check A/T fluid temp. sensor.
Check harness and connector between A/T fluid temp. sensor and ECM
(See page IN±30).
Replace A/T fluid temp. sensor.
Repair or replace harness or connector.
Check sensor resistance
Remove A/T fluid temp. sensor.
Measure resistance between terminals of A/T fluid
temp. sensor at 20°C (68°F) and 110°C (230°F).
Resistance:
20°C (68°F): Approx. 12.08 k

11 0°C (230°F): Approx. 0.78 k

20°C (68°F) and 110°C (230°F).
Check and replace ECM.

Check if A/T fluid temp. is too hot.
1. Turn ignition switch ON.
2. Check ªMANUº mode indicator light when pat-
tern select switch is pushed in to ON.
ºMANUº mode indicator light comes on and stays
on.
If the A/T fluid temp. becomes too hot, the ªMANUº
mode indicator light flashes for several seconds and
goes off. The driving mode then automatically
changes from Manual mode to the Normal mode.
Measure voltage between the terminal M of the
ECM connector and body ground when the pattern
select switch is set to the MANU (MANUAL) posi-
tion and NORM (NORMAL) position.
Check A/T fluid temp. sensor (See page AT2±70).
Check voltage between terminal M of ECM connector and body ground.
Replaces A/T fluid temp. sensor.
1. Connect the Check Harness A to the ECM
(See page EG±510).
2. Turn ignition switch ON.
Proceed to next circuit inspection shown on
matrix chart (See page AT2±64).
The ECM uses the Normal pattern signal if the
Manual signal is not input.

(e) Start the engine and shift the selector into all positions from
ºPº through ºLº, and then shift into ºPº position.
(f) With the engine idling, check the fluid level. Add fluid up the
ºCOOLº range on the dipstick. MA±14
± MAINTENANCEMAINTENANCE OPERATIONS

18. BRAKE PEDAL
(a) Check that pedal for smooth operation.
(b) Check that the pedal has the proper reserve
distance and freeplay.
(c) Check the brake booster function.
19. BRAKES
At a safe place, check that the brakes do not
pull to one side when applied.
20. PARKING BRAKE
(a) Check that the pedal has the proper travel.
(b) On a safe incline, check that the vehicle is
held securely with only the parking brake
applied.
21. AUTOMATIC TRANSMISSION PARK
MECHANISM
(a) Check the lock release button of the selector
lever for proper and smooth operation.
(b) On a safe incline, check that the vehicle is
held securely with the selector lever in the ºPº
position and all brakes released.
UNDER HOOD
22. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
23. ENGINE COOLANT LEVEL
Check that the coolant level is between the
LEVEL lines on the see±through reservoir at
normal temperature (20°C (68°F)).
24. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean
and not blocked with leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or
loose connections.
25. BATTERY ELECTROLYTE LEVEL
Check the indicator.
When the indicator color is blue, the condition
is satisfactory. A red color indicates that dis-
tilled water must be added, and white indi-
cates that charging is necessary.
26. BRAKE FLUID LEVEL
Check that the brake fluid level is near the up-
per level line on the see±through reservoir.27. ENGINE DRIVE BELT
Check drive belt for fraying, cracks, wear or
oil contamination.
28. ENGINE OIL LEVEL
Check that level on the dipstick with the en-
gine turned off.
29. POWER STEERING FLUID LEVEL
Check the level on the dipstick.
The level should be in the ºHOTº or ºCOLDº
range depending on the fluid temperature.
30. A U TO M AT I C TRANSMISSION FLUID
LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking and
foot brake applied, shift the selector into all
positions from ºPº to ºLº, and then shift into ºPº
position.
(c) Turn and pull out the dipstick and wipe off the
fluid with a clean rag.
Re±insert the dipstick fully and check that the
fluid level is in the ºHOTº range.
(d) Perform this check with the fluid at normal
driving temperature (70±80°C (158±176°F)).
If the level is at the low side, add fluid.
NOTICE: Do not overfill.
HINT: Wait about 30 minutes before checking
the fluid level after extended driving at high
speeds in hot weather, driving in heavy traffic
or with a trailer.
31. EXHAUST SYSTEM
Visually inspect for cracks, holes or loose
supports.
If any change in the sound of the exhaust or
smell of the exhaust fumes is noticed, have
the cause located and correted. MA±18
