BCM (Body Control Module): Configuration: Description
Vehicle specification needs to be written with CONSULT because it is not written after replacing BCM.
Configuration has three functions as follows:
| Function | Description |
|---|---|
| "Before Replace ECU" |
|
| "After Replace ECU" | Writes the vehicle configuration with manual selection. |
| "Select Saved Data List" | Writes the vehicle configuration with saved data. |
- When replaceing BCM, you must perform "Select Saved Data List" or "After Replace ECU" with CONSULT.
- Complete the procedure of "Select Saved Data List" or "After Replace ECU" in order.
- If you set incorrect "Select Saved Data List" or "After Replace ECU", incidents might occur.
- Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
- Never Perform "Select Saved Data List" or "After Replace ECU" except for new BCM.
