ECM
ECM : Description
INFOID:0000000007579663
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 by CONSULT is not necessary)
NOTE:
• 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.
ECM : Work Procedure
INFOID:0000000007579664
1.
PERFORM ECM RECOMMUNICATING FUNCTION
1.
Install ECM.
2.
Contact backside of registered Intelligent key* to push-button ignition switch, then turn power supply posi-
tion to ON.
*: To perform this step, use the key that is used before performing ECM replacement.
3.
Maintain power supply position in the ON position for at least 5 seconds.
4.
Turn power supply position to OFF.

BCM : Description
INFOID:0000000007579665
BEFORE REPLACEMENT
When replacing BCM, save or print current vehicle specification with CONSULT configuration before replace-
ment.
NOTE:
If “READ CONFIGURATION” can not be used, use the “WRITE CONFIGURATION - Manual selection” after
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.
• Complete the procedure of “WRITE CONFIGURATION” in order.
• Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
• If you set incorrect “WRITE CONFIGURATION”, incidents might occur.
NOTE:
When replacing BCM, perform the system initialization (NATS).
