ECD SYSTEM (w/o DPF) - REGISTRATION

1. REGISTRATION

NOTICE:

When a fuel injector is replaced, the new fuel injector compensation code must be input into the ECM. When the ECM is replaced, all of the existing fuel injector compensation codes must be input into the new ECM.

Fuel injector compensation codes are unique, 30 digit, alphanumeric values printed on the head portion of each fuel injector. If an incorrect fuel injector compensation code is input into the ECM, the engine assembly may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.

After replacing fuel injector(s) with new one(s), input compensation code(s) of fuel injector(s) into ECM as follows:

HINT:

Each fuel injector has different fuel injection characteristics. In order to optimize the fuel injections, the ECM uses the compensation codes to balance the different fuel injections between each fuel injector.

When you first turn the ignition switch to ON after replacing the ECM or a fuel injector(s), DTC P1601 is set. This is to inform you that registration of a fuel injector compensation code(s) is/are required. Manually clear the DTC upon completion of the compensation code registration.

Input the compensation code(s), which is/are imprinted on the head portion(s) of the new fuel injector(s), into the intelligent tester.

Input the new compensation code(s) into the ECM using the tester.

Turn the tester off and turn the ignition switch off.

Wait for at least 30 seconds.

Turn the ignition switch to ON and turn the tester on.

Connect the intelligent tester to the DLC3.

Turn the ignition switch to ON.

NOTICE:

Do not start the engine.

Turn the tester on.

Enter the following menus: 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 fuel injector compensation code that you want to read.

Press Next.

Press Input.

Manually input the cylinder compensation code using the keyboard on the tester screen. The code is a 30 digit, alphanumeric value printed on the injector head portion.

HINT:

Each fuel injector compensation code is unique. The compensation code for each selected cylinder must be input into the tester correctly.

Confirm that the compensation code 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 fuel 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.

HINT:

If a wrong compensation code is 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 DLC3 connection. If no problem is found with either, the ECM may be malfunctioning. Check the ECM and repeat this operation.

Press Next to register the compensation code in the ECM.

HINT:

If the registration process fails, the compensation code may be incorrect. Check the compensation code again.

If the input compensation code fails to register even though it is input correctly, there may be a problem with the wire harness or a bad connection with the DLC3. Check the wire harness and 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 ignition switch off and then turn the tester off.

Wait for at least 30 seconds.

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

2. READING REGISTERED DATA

NOTICE:

When a fuel injector is replaced, the new fuel injector compensation code must be input into the ECM. When the ECM is changed, all of the existing fuel injector compensation codes must be input into the new ECM.

Fuel injector compensation codes are unique, 30 digit, alphanumeric values printed on the head portion of each fuel injector. If an incorrect fuel 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.

When replacing ECM with a new one, input all fuel injector compensation codes into new ECM as follows:

HINT:

When you first turn the ignition switch to ON after replacing the ECM or a fuel injector(s), DTC P1601 is set. This is to inform you that registration of a fuel injector compensation codes(s) is/are required. Manually clear the DTC upon completion of the compensation code registration.

Prior to replacing the ECM, read and save each fuel injector compensation code, stored in the original ECM, using the intelligent tester.

After installing a new ECM, input the saved compensation codes into the new ECM using the tester.

Turn the tester off and turn the ignition switch off.

Wait for at least 30 seconds.

Turn the ignition switch to ON and turn the tester on.

HINT:

The following operation is available with ECMs that can transmit the registered fuel injector compensation codes to the intelligent tester.

Connect the intelligent tester to the DLC3.

Turn the ignition switch to ON.

NOTICE:

Do not start the engine.

Turn the tester on.

Enter the following menus: Powertrain / Engine / Utility / Injector Compensation.

Press Next.

Press Next again to proceed.

Press Next.

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

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 DLC3 connection. If no problem is found, the ECM may be malfunctioning. Check the ECM and restart this operation.

Check the fuel injector compensation code (30 digit alphanumeric value) displayed on the tester screen.

Press Save.

Check that the compensation code displayed on the tester screen is correct.

Press Save or Replace to save the fuel injector compensation code.

HINT:

The existing compensation code is overwritten with the new compensation code and is deleted from the tester.
