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.
When a fuel injector is replaced, perform pilot quantity learning. When the ECM is replaced, all of the existing fuel injector pilot quantity learning values must be input into the new ECM.
When replacing the ECM with a new one, if the injector compensation code and pilot quantity learning value are not entered or the injector compensation code is not registered correctly, DTC P062F will be stored.
When replacing the ECM with a new one, input all learning values and codes into the new ECM as follows:
Prior to replacing the ECM, use the GTS to read and save each learning value and code from the original ECM (Click here).
After installing a new ECM, input the saved learning values and codes into the new ECM using the GTS (Click here).
Turn the ignition switch off and turn the GTS off.
Wait for at least 30 seconds.
Turn the ignition switch to ON and turn the GTS on.
Clear DTC P062F stored in the ECM using the GTS.
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 injector.
When you first turn ON the ignition switch after replacing the ECM and other component(s), DTC P062F is stored. Manually clear the DTC upon completion of compensation code registration.

CAUTION / NOTICE / HINT
After replacing the ECM, the new ECM needs registration (See page ) and initialization (Click here).
After replacing the fuel supply pump assembly, the ECM needs initialization (Click here).
After replacing an injector assembly, the ECM needs registration (Click here).
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
PROCEDURE
