IMMOBILIZER SYSTEM COMPONENT REPLACEMENT/KEY ADDITION AND
CLEARING[ADVANCED KEYLESS SYSTEM]
FOREWORD
When performing the following procedures, the immobilizer resetting procedure using the M-MDS must
also always be performed: "Keyless control module replacement", "PCM replacement", "Steering lock
unit replacement", "Keyless control module and PCM joint replacement", "Keyless control module, PCM,
and steering lock unit joint replacement", and "Key ID number clearing". The engine will not start unless
all work is performed using the M-MDS.
A card key that can start the engine is necessary for the key programming. If there is no card key that can
start the engine, perform the key programming after the card key programming.(See
CARD KEY ID
CODE REGISTRATION[ADVANCED KEYLESS SYSTEM]
.)
There are two ways to add supplemental key: Using the M-MDS or using two keys that can start the
engine to program.
When replacing any of the immobilizer system component parts, adding/clearing keys, or performing
other functions, refer to the following table and perform the applicable procedure (No.1 to 5).
Verify that the room fuse is equipped.
