ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : DESCRIPTION

When replacing BCM, save or print current vehicle specification with CONSULT-III configuration before replacement.

Configuration has three functions as follows

  1. READ CONFIGURATION is the function to read (extract) vehicle configuration of current BCM.
  2. WRITE CONFIGURATION - Manual selection is the function to select and write vehicle configuration on BCM manually.
  3. WRITE CONFIGURATION - Config file is the function to write vehicle configuration with the data extracted from current BCM.
CAUTIONWhen 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 will occur. Configuration is different for each vehicle model. Confirm configuration of each vehicle model.

CONFIGURATION : DESCRIPTION

Vehicle specification needs to be written with CONSULT-III because it is not written after replacing BCM.

  1. READ CONFIGURATION is the function to read (extract) vehicle configuration of current BCM.
  2. WRITE CONFIGURATION - Manual selection is the function to select and write vehicle configuration on BCM manually.
  3. WRITE CONFIGURATION - Config file is the function to write vehicle configuration with the data extracted from current BCM.

DESCRIPTION

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern vehicle is equipped with many electronic control unit, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

OPERATION PROCEDURE

  1. Connect both battery cables. NOTE: Supply power using jumper cables if battery is discharged.
  2. Use the Intelligent Key or mechanical key to turn the ignition switch to the "ACC" position. At this time, the steering lock will be released.
  3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
  4. Perform the necessary repair operation.
  5. When the repair work is completed, return the ignition switch to the "LOCK" position before connecting the battery cables. (At this time, the steering lock mechanism will engage.)
  6. Perform a self-diagnosis check of all control units using CONSULT-III.
