ECM : Description

INFOID:0000000009650707

Performing the following procedure can automatically activate recommunication of ECM and BCM, but only
when the ECM is replaced with a new one*.
*: New one means a virgin ECM that has never been energized on-board.
(In this step, initialization procedure using CONSULT is not necessary)
NOTE:
• When registering new Key IDs or replacing the ECM that is not brand new, the initialization of BCM

using CONSULT is necessary.

• If multiple keys are attached to the key holder, separate them before beginning work.
• Distinguish keys with unregistered key IDs from those with registered IDs.

replacing BCM.

AFTER REPLACEMENT

CAUTION:

When replacing BCM, always perform “WRITE CONFIGURATION” with CONSULT. Or not doing so,
BCM control function does not operate normally.
