|---|---|
| "Before Replace ECU" | Reads the vehicle configuration of current AV control unit. Saves the read vehicle configuration. |
| "After Replace ECU" | Writes the vehicle configuration with manual selection. |
| "Select Saved Data List" | Writes the vehicle configuration with saved data. |
| CAUTION | When replacing AV control unit, 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 AV control unit. |
