DIAGNOSIS FUNCTION
1. |
Connect the Hi Scan Pro to the connector for
diagnosis. |
2. |
Read the output diagnostic trouble codes. Then
follow the remedy procedures according to the "DIAGNOSTIC TROUBLE
CODE DESCRIPTION" on the following pages.
•
|
A maximum of 8 diagnostic trouble
codes (in the sequence of occurrence) can be stored in
the Random Access Memory (RAM) incorporated within the
control module. |
•
|
The same diagnostic trouble code
can be stored one time
only. |
•
|
If the number of stored diagnostic
trouble codes or diagnostic trouble patterns exceeds 8,
already stored diagnostic trouble codes will be erased
in sequence, beginning with the
oldest. |
•
|
Do not disconnect the battery
until all diagnostic trouble codes or diagnostic trouble
patterns have been read out, because all stored
diagnostic trouble codes or diagnostic trouble patterns
will be cancelled when the battery is
disconnected. | | |
3. |
If the fail-safe system is activated and the
transaxle is locked in third gear, the diagnostic trouble code in
the Fail-safe code description will be stored in the RAM. Three of
these diagnostic trouble codes can be
stored. |
4. |
The cancellation will occur if, with the
transaxle locked in third gear, the ignition key is turned to the
OFF position, but the diagnostic trouble code is stored in the
RAM. |
5. |
Memorization.
A. |
Up to 8 diagnosis items and 3 fail-safe
items can be memorized. |
B. |
If the memory capacity is exceeded,
diagnosis and fail-safe items in the memory are overwritten,
starting with the oldest. |
C. |
No code can be memorized more than
once. | |
6. |
Diagnosis Code Deletion.
(1) |
Automatic Deletion
All diagnosis codes are deleted from
memory the 200 th time the ATF temperature reaches 50°C after
memorization of the most recent diagnosis
code. |
(2) |
Forced Deletion
Memorized diagnosis codes can be deleted
using the scan-tool, provided the following conditions are
satisfied :
A. |
The ignition switch is
ON |
B. |
There is no detection pulse from
the crank angle sensor |
C. |
There is no detection pulse from
the output shaft speed
sensor |
D. |
There is no detection pulse from

shocks occur when driving due to upshifting or downshifting and the
transmission speed becomes higher than the engine speed, the cause
is probably abnormal line pressure or a malfunction of a solenoid
valve, oil pump, valve body, brake or clutch.

Displaced shifting points
|
All points If all shift points
are displaced while driving, the cause is probably a malfunction of
the output shaft speed sensor, TPS or solenoid valve.

Malfunction of the valve
body |
|
Some points If some of the
shift points are displaced while driving, the cause is probably a
malfunction of the valve body, or it is related to control and is
not an abnormality.

Does not
shift
|
No diagnosis codes If shifting
does not occur while driving and no diagnosis codes are set, the
cause is probably a malfunction of the transaxle range switch, or
TCM

|
Malfunction of the transaxle

|
Malfunction while
driving
|
Poor a acceleration If
acceleration is poor even if downshifting occurs while driving, the
cause is probably a malfunction of the engine system, brake or
clutch.

|
Vibration If vibration occurs
when driving at constant speed or when accelerating and deceleration
in top range, the cause is probably abnormal damper clutch pressure
or a malfunction of the engine system, damper clutch control
solenoid valve, torque converter or valve body.
