ON-VEHICLE INSPECTION
HINT:
It is normal for the cooling fan to sometimes rotate when the
ignition switch is turned from ACC to ON.
1. CHECK COOLING FAN OPERATION AT LOW
TEMPERATURES (Below 94
C (201F))
(a) Turn the ignition switch ON with the A/C switch OFF.
(b) Check that the cooling fan stops.
If it does not, check the cooling fan relays and
engine coolant temperature sensor, and then check
for disconnection of the connector or wire breaks
between the cooling fan relay and engine coolant
temperature sensor.
(c) Disconnect the engine coolant temperature sensor
connector.
(d) Check that the cooling fan rotates.
If it does not, check the fuses, cooling fan relays,
ECM and cooling fan, and then check for an open
circuit between the cooling fan relay and engine
coolant temperature sensor.
(e) Reconnect the engine coolant temperature sensor
connector.
2. CHECK COOLING FAN OPERATION AT HIGH
TEMPERATURES (Above 96
C (205F))
(a) Start the engine, and then raise the coolant
temperature to above 96
C (205F).
HINT:
Coolant temperature is the value detected by the
engine coolant temperature sensor on the cylinder
head.
(b) Check that the A/C switch is OFF.

(c) Check that the cooling fan rotates.
If it does not, check the engine coolant temperature
sensor, cooling fan, harness or connector.

ROAD TEST
1. PROBLEM SYMPTOM CONFIRMATION
(a) Based on the result of the customer problem
analysis, try to reproduce the symptoms. If the
problem is that the transaxle does not shift up, shift
down, or the shift point is too high or too low,
conduct the following road test referring to the
automatic shift schedule and simulate the problem
symptoms.
2. ROAD TEST
NOTICE:
Perform the test at the normal operating ATF
temperature of 50 to 80
C (122 to 176F).
(a) D position test
Move the shift lever to D and fully depress the
accelerator pedal. Check the following:
(1) Check up-shift operation.
Check that the 1
2, 2 3 and 3 O/D up-
shifts take place at the shift point shown in the
automatic shift schedule (see page SS-55).
HINT:
O/D Gear Up-shift Prohibition Control
• Engine coolant temperature is 55
C (131F)
or less and vehicle speed is at 70 km/h (43
mph) or less.
• ATF temperature is 5
C (41F) or less.
O/D Gear Lock-up Prohibition Control
• Brake pedal is depressed.
• Accelerator pedal is released.
• Engine coolant temperature is 60
C (140F)
or less.
(2) Check for shift shock and slip.
Check for shock and slip at the 1
2, 2 3 and
3
O/D up-shifts.
(3) Check for abnormal noise and vibration.
Check for abnormal noise and vibration when
up-shifting from 1
2, 2 3 and 3 O/D while
driving with the shift lever on D, and check while
driving in the lock-up condition.
HINT:
The check for the cause of abnormal noise and
vibration must be done thoroughly as it could
also be due to loss of balance in the differential,
torque converter clutch, etc.
(4) Check kick-down operation.
While driving the vehicle in the 2nd, 3rd and O/D
gears with the shift lever on D, check that the
possible kick-down vehicle speed limits for 2

1, 3
2 and O/D 3 kick-downs conform to
those indicated in the automatic shift schedule
(see page SS-55).
(5) Check for abnormal shock and slip at kick-down.
