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