ECU by ones when the multiple ECU is replaced, and then replace the next ECU after registering
the necessary IDs [Refer to GROUP 54E, Troubleshooting - Encrypted Code Registration
Criteria Table <3,200> ].
When the engine-ECU is replaced, register the injector identification code and perform
the fuel injection learning (Refer to GROUP 00 - Precautions Before Service - What
The Common Rail Engine Learns ).
