P.00-40

].

• When the ECM is replaced, save the vehicle identification number and perform the variant coding.
• After the ECM replacement, idling speed may be unstable because the MFI engine learning is not 

completed. To make it stable, let the system learn the idling (Refer to GROUP 00, Precautions 
before Service 

− Learning Procedure for Idling in MFI Engine
