ECM RE-COMMUNICATING FUNCTION
ECM RE-COMMUNICATING FUNCTION : DescriptionINFOID:0000000012430463
Performing following procedure can automatically per
form re-communication of ECM and BCM, but only when
the ECM has been replaced with a new one (*1).
*1: New one means an ECM which has never been energized on-board.
(In this step, initialization procedure by CONSULT is not necessary)
NOTE:
• When registering new Key IDs or replacing the ECM that is not brand new, refer to CONSULT Immo-
bilizer mode and follow th e on-screen instructions.
• If multiple keys are attached to the key holder, separate them before work.
• Distinguish keys with unregistered key ID from those with registered ID.
