Diamante, Eclipse, GALANT, Montero & Montero Sport: Introduction

When replacing the PCM, it will be necessary to reregister all ignition keys with the immobilizer-ECU. See KEY ID REGISTRATION (USING MUT-II SCAN TOOL)  or KEY ID REGISTRATION (USING MUT-III SCAN TOOL)  . Since Lancer and Outlander are not equipped with the imobilizer-ECU, the ignition key registration does not apply to them.
