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.
