CHECK TRANS INDICATOR & SELF DIAGNOSIS
CHECK
TRANS
Warning to the driver
"CHECK TRANS" is ON during 3 seconds at key switch ON
position.
When trouble has occurred to electrical components,
"CHECK TRANS" lamp is blinked (1.25 Hz) even during
driving to warn the driver.
The trouble is recorded by trouble code in TCM. When
temporary trouble code has been canceled, the "CHEC
K
TRANS" lamp stops blinking. This blinking can be stopped
by setting the key off. But the trouble code remains
memorized in TCM.

NOTE:
1. If the "CHECK TRANS" lamp is staying ON always at key
switch ON position, this means that connection between the
lamp and TCM is shorted to ground.
Verify connection and wire between the TCM A20 terminal
and lamp short to ground.
2. If the "CHECK TRANS" lamp is staying OFF at key switch
ON position (Engine off), this means that connection
between the lamp and TCM is opened or meter fuse (15A)
is burnt out.
Verify connection and wire between the TCM A20 terminal
and lamp open circuit and meter fuse (15A).

Data Link Connector Short Circuit
Self-diagnosis code (Flash code) display
The stored trouble codes can be identified by shorting the
terminal No. 11 and No. 4 or 5 (ground) of data link
connector with a lead wire.
Indication Method:
1. Terminal No. 11 and No. 4 or 5 (ground) of data link
connector are short circuited.
2. Turn the key switch to the ON position.
3. In case no trouble code existence, normal code (12) is
indicated repeatedly.

Trouble Code Clear Method:
If you have Tech 2:
Follow the procedure "DIAGNOSIS WITH TECH 2" in this
manual.
If you have no Tech 2:
Remove ECM (B) slow blow fuse (30A) for at least 10 seconds.
NOTE:
If you clear the DTC you will not be able to read any codes
recorded during the last occurrence.
To use the DTC again to identify a problem, you will need
to reproduce the fault or the problem. This may require a
new test drive or just turning the key switch on (this
depends on the nature of the fault).

DIAGNOSIS (JR405E) 7A2-9
DIAGNOSIS WITH TECH 2
In this JR405E transmission, troubleshooting can be performed for electrical faults using the Tech 2 scan tool.
If the "CHECK TRANS" lamp blinks, or if an electrical fault in the transmission may probably exit, check trouble
codes using the Tech 2 scan tool.
In the diagnostic procedures described in this manual, first repair the faulty positions indicated by trouble code in
order of numbers and then perform troubleshooting for the faulty positions that are not indicated by trouble code.
For correct troubleshooting, it is necessary to first repair the trouble codes of lower order numbers, then to repair
the trouble codes of higher order numbers in sequence.
If no codes are set:
Refer to F1: Data Display and identify the electrical faults that are not indicated by trouble code.
Refer to "SYMPTOM DIAGNOSIS".
If codes are set:
1. Record all trouble codes displayed by Tech 2 and check id the codes are intermittent.
2. Clear the codes.
3. Drive the vehicle for a test to reproduce the faulty status.
4. Check trouble codes again using the Tech 2.
5. If no codes is displayed by test driving, the fault is intermittent. In this case, refer to "INTERMITTENT
DIAGNOSIS".
6. If a code is present, refer to DTC Chart for diagnosis.
7. Check trouble codes again using the Tech 2.
TECH 2 CONNECTION
Tech 2 scan tool is used to electrically diagnose the automatic
transmission system and to check the system. The Tech 2
enhances the diagnosis efficiency though all the
troubleshooting can be done without the Tech 2.
1. Configuration of Tech 2
Tech 2 scan tool kit (No. 7000086), Tech 2 scan tool
(No. 7000057) and DLC cable (No. 3000095).
SAE 16/19 adapter (No. 3000098) (1), RS232 loop back
connector (No. 3000112) (2) and PCMCIA card (No.
3000117) (3).
2. Tech 2 Connection
Check the key switch is turn OFF.
Insert the PCMCIA card (1) into the Tech 2 (4).
Connect the SAE 16/19 adapter (2) to the DLC cable (3).
Connect the DLC cable (3) to the Tech 2 (4).
Connect the SAE 16/19 adapter (2) to the data link
connector of the vehicle.
Turn the key switch of the vehicle ON and press the
"PWR" key of the Tech 2.
Check the display of the Tech 2.

MISCELLANEOUS TEST
The state of each circuit can be tested by using miscellaneous test menus. Especially when DTC cannot be
detected, a faulty circuit can be diagnosed by testing each circuit by means of these menus.
Even DTC has been detected, the circuit tests using these menus could help discriminate between a mechanical
trouble and an electrical trouble.
Connect Tech 2 and select "Powertrain", "JR 405E" & "Miscellaneous Test".
F0: Lamps
The circuit is normal if the warning light in the meter panel comes on and goes out in accordance with Tech 2

SERVICE PROGRAMMING SYSTEM (SPS)
The procedure to program the control unit by using Service Programming System (SPS) software contained in TIS
2000 is explained in steps below.
Important: Perform the following checks before attempting to program the control unit:
The Tech 2 PCMCIA card is programmed with the latest software release.
The latest release of TIS2000 is located on the PC.
The vehicle battery is fully charged.
The control unit to be programmed is connected to the vehicle.
1. Preparations of TIS 2000
1. Connect Tech 2 to P/C.
2. Check to see if Hardware Key is plugged into Port.
3. Activate TIS 2000 by P/C.
4. On the activating screen of TIS2000, choose "Service Programming System"
5. On the screen of "Diagnostic Tester and Processing Program Selection", choose the one that will comply with
the following.
Diagnostic Tech2 in use
New programming by the existing module or new programming by the replaced/new module.
Fixing position of the control unit.
6. Upon completion of the selection, push the button of "Next".
2. Demand of Data
1. Connect Tech-2 to the vehicle. When activated by turning on the power of Tech-2, push the "Enter" switch.
2. Turn on the ignition switch (without starting the engine).
3. In the main menu of Diagnostic Tester, push "F1: Service Programming System (SPS)".
4. Push "F0: Request Info" of Tech-2.
5. Where vehicle data has been already saved in Tech 2, the existing data come on display. In this instance, as Tech-2 starts asking whether to keep the data or to continue obtaining anew data from the control unit,
