1. LEARNING VALUES CONFIRMATION

This procedure uses the GTS to save the learned values (injector compensation code) stored in the ECM.

HINT:

A malfunction may occur when reading the values if there is a problem with the ECM, a wire harness or the connection to the DLC3. If the wire harnesses and the connection to the DLC3 are inspected and found to be normal, the ECM may be malfunctioning.

Connect the GTS to the DLC3.

Turn the ignition switch to ON and turn the GTS on.
NOTICE:
Do not start the engine.

Enter the following menus: Powertrain / Engine and ECT / Utility / Learning values confirmation.

Press "Next".

Press "Next" again to proceed.

Select the value to confirm and press "Next".

When the next screen is displayed, confirm the contents and press "Exit".

2. LEARNING VALUES SAVE

This procedure uses the GTS to save the learned values (injector compensation code) stored in the ECM in the GTS depending on the components being replaced.

HINT:

When replacing the engine assembly, fuel injector together with the ECM, this function automatically determines the data which can be transferred (old data) and saves the data in the GTS.

When there is no data to read from the ECM, manually perform the procedure to register each compensation code and learning value in the ECM.

A malfunction may occur when reading the values if there is a problem with the ECM, a wire harness or the connection to the DLC3. If the wire harnesses and the connection to the DLC3 are inspected and found to be normal, the ECM may be malfunctioning.

Connect the GTS to the DLC3.

Turn the ignition switch to ON and turn the GTS on.
NOTICE:
Do not start the engine.

Enter the following menus: Powertrain / Engine and ECT / Utility / Learning values save.

Press "Next".

Press "Next" again to proceed.

Select any components being replaced and press "Next". If no applicable components are displayed, press "Next" without selecting anything.

If the overwrite confirmation screen is displayed, press "Overwrite".

When the operation is finished, confirm the date and time of the save operation, and press "Exit".

3. LEARNING VALUES WRITE

This procedure uses the GTS to write all of the learned values (injector compensation code) stored in the GTS to the ECM.

HINT:

A malfunction may occur when writing the values if there is a problem with the ECM, a wire harness or the connection to the DLC3. If the wire harnesses and the connection to the DLC3 are inspected and found to be normal, the ECM may be malfunctioning.

Connect the GTS to the DLC3.

Turn the ignition switch to ON and turn the GTS on.
NOTICE:
Do not start the engine.

Enter the following menus: Powertrain / Engine and ECT / Utility / Learning values write.

Press "Next".

Press "Next" again to proceed.

If the "Error Learning Values Write" screen indicating a problem with the saved value(s) or an absence of saved values is displayed, perform "Learning Values Save" again.

Confirm the date and time of the save operation, and then press "Yes".

Confirm the contents, and then press "Next".

If any instructions are displayed on the GTS, manually perform the procedure to register each applicable compensation code or learning value in the ECM.

Clear the DTCs.

4. AFTER REPLACING INJECTOR(S) WITH NEW ONE(S), INPUT COMPENSATION CODE(S) OF INJECTOR(S) INTO ECM AS FOLLOWS:

NOTICE:

When an injector is replaced, the injector's compensation code must be input into the ECM. When the ECM is changed, all of the existing injector compensation codes must be input into the new ECM.
Injector compensation codes are unique, 30-digit, alphanumeric values printed on the head portion of each injector. If an incorrect injector compensation code is input into the ECM, the engine may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.

Connect the GTS to the DLC3.

Turn the ignition switch to ON and turn the GTS on.
NOTICE:
Do not start the engine.
HINT:
The injector compensation code is imprinted on the head portion of each injector.

Enter the menu options in this order: Powertrain / Engine and ECT / Utility / Injector Compensation.

Press Next.

Press Next again to proceed.

Select "Set Compensation Code".

Press Next.

Select the number of the cylinder corresponding to the injector compensation code that you want to read.

Press Next.

Register compensation code.
1. Press input.
2. Manually input the cylinder's compensation code using the keyboard on the GTS screen. The code is a 30-digit, alphanumeric value imprinted on the injector's head portion.
  HINT:
  Each injector compensation code is unique. The correct compensation code must be input into each cylinder selected on the GTS.
3. Confirm that the compensation code is correct for the selected cylinder is correct, and then press OK.

Check that the compensation code displayed on the screen is correct, by comparing it with the 30-digit alphanumeric value on the head portion of the fuel injector.
NOTICE:
If an incorrect injector compensation code was input into the ECM, the engine may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.
HINT:
If a wrong compensation code was input or read, return to the input Value screen by pressing input. The saving process may fail due to a problem with the wire harness or a bad connection with the DLC3. Check the wire harness and the DLC3 connection. If no problem is found with either, the ECM may be malfunctioning. Check the ECM and repeat this operation.

Press Next to set the compensation code to the ECM.
HINT:
1. If the setting process fails, the compensation code may be incorrect. Check the compensation code again.
2. If the attempted compensation code is correct, a problem with the wire harness or a bad connection with the DLC3 may cause the failure. Check the wire harness and the DLC3 connection. If no problem is found with either, the ECM may be malfunctioning. Check the ECM and restart this operation.

If you want to continue with other compensation code registrations, press Next. To finish the registration, press Cancel.

Turn the GTS OFF and then turn the ignition switch OFF.

Wait for at least 30 seconds.

Turn the ignition switch to ON and then turn the GTS on.

5. WHEN REPLACING ECM WITH NEW ONE, INPUT ALL INJECTOR'S COMPENSATION CODES INTO NEW ECM AS FOLLOWS:

NOTICE:

When an injector is replaced, the injector's compensation code must be input into the ECM. When the ECM is changed, all of the existing injector compensation codes must be input into the new ECM.
Injector compensation codes are unique, 30-digit, alphanumeric values printed on the head portion of each injector. If an incorrect injector compensation code is input into the ECM, the engine may rattle or engine idling may become rough.
