Removal and Replacement

ENGINE CONTROL MODULE (ECM) AND POWERTRAIN CONTROL MODULE (PCM)

REMOVAL AND INSTALLATION

CAUTION:
- Do not replace the ECM [M/T] or PCM [A/T] and the ETACS-ECU simultaneously. Always replace either one of the ECUs first, and register the encrypted code (Refer to chassis electrical, Immobilizer System -Encrypted Code Registration Criteria Table). Then, replace the other ECU.
- After the ECM [M/T] or PCM [A/T] is replaced, idling speed may be unstable because the MPI engine learning is not completed. To make it stable, make the system learn the idling (Refer to general (body and chassis) -Precautions before Service, Learning Procedure for Idling in MFI Engine).
