Removal and Replacement

ENGINE CONTROL MODULE (ECM)

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.
- 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.
- After the replacement of the ECM, register a key code using scan tool.
- When the ECM is replaced, saved the vehicle identification number and perform the variant coding.
