Ecd System -- Registration

NOTICE:

When an injector is replaced, the injector's compensation code must be input into the ECM (Proceed to step 1).
When the ECM is changed, all of the existing injector compensation codes must be input into the new ECM (Proceed to step 2).

1. INPUT INJECTOR COMPENSATION CODE

NOTICE:

Injector compensation codes are unique, 30-digit, and 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 intelligent tester to the DLC3.

Turn the engine switch ON (IG).

Turn the tester 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 / 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 the compensation code.
1. Press "Input".
2. Manually input the cylinder's compensation code using the keyboard on the tester 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 tester.
3. Confirm that the compensation code is correct for the selected cylinder, 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 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:
1. If a wrong compensation code was input or read, return to the "Input Value" screen by pressing "Input".
2. 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, 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, the ECM may be malfunctioning. Check the ECM and repeat this operation.

To continue with compensation code registrations for other cylinders, press "Next". To finish the registration, press "Cancel".

Turn the engine switch OFF and then turn the tester OFF.

Wait for at least 30 seconds.

Turn the engine switch ON (IG) and then turn the tester ON.

2. INPUT ALL INJECTORS COMPENSATION CODES AND TRANSFER CATALYST RECORD OF DPNR THERMAL DETERIORATION

NOTICE:

HINT:

The following operation is available with ECMs that can transmit the registered injector compensation codes and catalyst record of DPNR thermal deterioration to the intelligent tester.

Read the catalyst record of DPNR thermal deterioration.
1. Connect the intelligent tester to the DLC3.
2. Turn the engine switch ON (IG).
3. Turn the tester ON.
  NOTICE:
  Do not start the engine.
4. Enter the menu options in this order: Powertrain / Engine / Utility / Catalyst Record Transferring.
5. Press "Next".
6. Press "Next" again to proceed.
7. Press "Next" again to proceed.
8. Select "Step 1 Read catalyst record".
9. Press "Next".
10. Confirm the catalyst record and press "Next".
  NOTICE:
  If a code cannot be read, replace the DPNR catalyst with a new one.
  HINT:
  When installing a new ECM that has registered catalyst record such as "FFFFFFFF", perform the procedures below by following the prompts on the tester screen.
  1. When replacing only the ECM, be sure to transfer the catalyst record from the removed ECM to the new ECM.
  2. When replacing the DPNR catalyst, clear the catalyst record registered in the ECM (Click here).
11. If the catalyst record has already been stored in the tester, the message in the illustration will appear. Press "Replace".
12. Press "Exit".

Read the injector compensation codes.
1. Enter the menu options in this order: Powertrain / Engine / Utility / Injector Compensation.
2. Press "Next".
3. Press "Next" again to proceed.
4. Select "Read Compensation Code".
5. Press "Next".
6. Select the number of the cylinder corresponding to the injector compensation code that you want to read.
7. Press "Next".
  HINT:
  The reading 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, the ECM may be malfunctioning. Check the ECM and repeat this operation.
8. Check that the injector compensation code (30-digit alphanumeric value) is displayed on the tester screen.
9. Press "Save".
10. Check that the compensation code displayed on the tester screen is correct.
11. Press "Save" or "Replace" to save the injector compensation code.
  HINT:
  1. The existing compensation code is overwritten with the new compensation code and is deleted from the tester.
  2. 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, the ECM may be malfunctioning. Check the ECM and repeat this operation.
12. To read and save injector compensation codes for other cylinders, press "Next" to continue. To finish this operation, press "Cancel".
