REMOVAL AND INSTALLATION

caution

When the ECM is replaced, do not replace the immobilizer ECU (WCM) or KOS-ECU simultaneously. When multiple ECUs are to be replaced, always replace only one ECU at a time and complete necessary ID registration using scan tool (Refer to GROUP 42B, Diagnosis - ID Codes Registration Judgment Table ) <Vehicle with KOS installed> or (Refer to GROUP 42C, Diagnosis - ID Codes Registration Judgment Table ) <Vehicle with WCM installed>.
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 - Engine Idling Learning Procedure .)
After the replacement of the ECM, register a key code using scan tool [Refer to GROUP 00, Precautions Before Service - How to Perform Vehicle Identification Number (VIN) Writing .]
When the ECM is replaced, saved the vehicle identification number and perform the variant coding.
