DESCRIPTION
CONFIGURATION has two functions as follows:

READ CONFIGURATION is the function to confirm vehicle configuration of current BCM.

WRITE CONFIGURATION is the function to write vehicle configuration on BCM.
CAUTION:

When replacing BCM, you must perform WRITE CONFIGURATION with CONSULT-II.

Complete the procedure of WRITE CONFIGURATION in order.

If you set incorrect WRITE CONFIGURATION, incidents will occur.

Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
READ CONFIGURATION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carries out CAN communication.
1. With ignition switch OFF, connect CONSULT-II and CONSULT-II
CONVERTER to data link connector and turn ignition switch ON.
