4. PROBLEM SYSMPTOMS TABLE
NOTICE:
When replacing the internal mechanism (computer part) of the audio system, be careful that no part
of your body or clothing comes in contact with the terminals of the leads from the IC, etc. of the re-
placement part (spare part).
HINT:
This inspection procedure is a simple troubleshooting which should be carried out on the vehicle during sys-
tem operation and was prepared on the assumption of system component troubles (except for the wires and
connectors, etc.).
Always inspect the trouble taking the following items into consideration.
Open or short circuit of the wire harness
Connector or terminal connection fault

9. PROBLEM SYMPTOM CONFIRMATION
Taking into consideration the results of the customer problem analysis, try to reproduce the symptoms. If the
problem is that the transmission 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.
10. ROAD TEST
NOTICE:
Perform the test at normal operating ATF temperature 50 to 80°C (122 to 176°F).
(a) D position test (NORM and PWR pattern):
Shift into the D position and fully depress the accelerator pedal and check the following points.
(1) Check up-shift operation.
Check that 1 " 2, 2 " 3, 3 " 4 and 4 " 5th up-shifts take place, and that the shift points conform
to the automatic shift schedule (See page SS-23).
HINT:

5th Gear Up-shift Prohibition Control (1. Coolant temp. is 55°C (131°F) or less. 2. Vehicle speed is
51 km/h (32 mph) or less.)

4th Gear Up-shift Prohibition Control (1. Coolant temp. is 40°C (104°F) or less. 2. Vehicle speed is
45 km/h (28 mph) or less.)

5th Gear Lock-up Prohibition Control (1. Brake pedal is depressed. 2. Coolant temp. is 60°C (140°F)
or less.)

When the 2nd start switch is on, there is no 1"2 up-shift and 2"1 down-shift.
(2) Check for shift shock and slip.
Check for shock and slip at the 1 " 2, 2 " 3, 3 " 4 and 4 " 5th up-shifts.
(3) Check for abnormal noises and vibration.
Drive in the D position lock-up or 5th gear and check for abnormal noises and vibration.
HINT:
The check for the cause of abnormal noises and vibration must be done very thoroughly as it could also be
due to loss of balance in the differential, torque converter clutch, etc.
(4) Check kick-down operation.
While running in the D position, 2nd, 3rd, 4th and 5th gears, check that the possible kick-down
vehicle speed limits for 2 " 1, 3 " 2, 4 " 3 and 5th " 4 kick-downs conform to those indicated
on the automatic shift schedule (See page SS-23).
(5) Check abnormal shock and slip at kick-down.
(6) Check the lock-up mechanism.

Drive in D position 5th gear, at a steady speed (lock-up ON) of about 70 km/h (43 mph).

Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
If there is a big jump in engine speed, there is no lock-up.
(b) 4 position test:
Shift into the 4 position and fully depress the accelerator pedal and check the following points.
(1) Check up-shift operation.
Check that the 1 " 2, 2 " 3 and 3 " 4 up-shift takes place and that the shift point conforms
to the automatic shift schedule (See page SS-23).
HINT:

There is no 5th up-shift in the 4 position.

4th Gear Lock-up Prohibition Control (1. Brake pedal is depressed. 2. Coolant temp. is 60°C (140°F)
or less.)

(2) Check engine braking.
While driving in the 4 position and 4th gear, release the accelerator pedal and check the engine
braking effect.
(3) Check for abnormal noises during acceleration and deceleration, and for shock at up-shift and
down-shift.
(4) Check the lock-up mechanism.

Drive in 4 position 4th gear, at a steady speed (lock-up ON) of about 64 km/h (40 mph).

Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
If there is a big jump in engine speed, there is no lock-up.
(c) 3 position test:
Shift into the 3 position and fully depress the accelerator pedal and check the following points.
(1) Check up-shift operation.
Check that the 1 " 2 and 2 " 3 up-shift takes place and that the shift point conforms to the auto-
matic shift schedule (See page SS-23).
(2) Check engine braking.
While running in the 3 position and 3rd gear, release the accelerator pedal and check the engine
braking effect.
(3) Check for abnormal noises during acceleration and deceleration, and for shock at up-shift and
down-shift.
(d) 2 position test:
Shift into the 2 position and fully depress the accelerator pedal and check the following points.
(1) Check up-shift operation.
Check that the 1 " 2 up-shift takes place and that the shift point conforms to the automatic shift
schedule (See page SS-23).
HINT:
When the 2nd start switch is ON, there is no 1 "2 up-shift and 2 "1 down-shift.
(2) Check engine braking.
While running in the 2 position and 2nd gear, release the accelerator pedal and check the engine
braking effect.
(3) Check for abnormal noises during acceleration and deceleration, and for shock at up-shift and
down-shift.
(e) L position test:
Shift into the L position and fully depress the accelerator pedal and check the following points.
(1) Check no up-shift.
While running in the L position, check that there is no up-shift to 2nd gear.
(2) Check engine braking.
While running in the L position, release the accelerator pedal and check the engine braking ef-
fect.
(3) Check for abnormal noises during acceleration and deceleration.
(f) R position test:
Shift into the R position, lightly depress the accelerator pedal, and check that the vehicle moves back-
ward without any abnormal noise or vibration.
CAUTION:
Before conducting this test ensure that the test area is free from people and obstruction.
