Description

INFOID:0000000008460434

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) (if equipped).

Work Procedure

INFOID:0000000008460435

Perform “READ CONFIGURATION” to save or print current vehicle specification. Refer to

BCS-63, "Descrip-

tion"

NOTE:
If “READ CONFIGURATION” can not be used, use the “WRITE CONFIGURATION - Manual selection” after
replacing BCM.
