CODING LIST
 
 
cautionWith the ETACS functions being customized, if any of the ETACS-ECU variant coding and option coding items are changed, the customized contents are reset. In such case, the functions need to be recustomized.
Before troubleshooting, check that the coding data written into the engine control module, SRS-ECU and ETACS-ECU are normal. If they are not the same as the initial settings, various functions and systems do not work normally.

cautionTo prevent damage to scan tool (M.U.T.-III), always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool (M.U.T.-III).
1. Ensure that the ignition switch is at the "LOCK" (OFF) position.
2. Start up the personal computer.
3. Connect special tool MB992747/M992748 or special tool MB991827 to special tool MB992744 or special tool MB991824 and the personal computer.
4. Connect special tool MB992745 or special tool MB991910 to special tool MB992744 or special tool MB991824.
5. Connect special tool MB992745 or special tool MB991910 to the data link connector.
noteWhen the special tool MB992745 is connected to the data link connector, the special tool MB992744 indicator light will be illuminated in a green color.
6. Turn the power switch of special tool MB991824 to the "ON" position. <When using the special tool MB991824>
noteWhen special tool MB991824 is energized, special tool MB991824 indicator light will be illuminated in a green color.
7. Start the M.U.T.-III system on the personal computer and turn the ignition switch to the "ON" position.
8. On the system selection screen, select "MFI" to check the engine control module data, "SRS-AIR BAG" to check the SRS-ECU data, and "ETACS" to check the ETACS-ECU data.
9. Select "Coding."
10. Select "Coding Information & Copy."
11. If the displayed coding information is different from the corresponding initial setting in the list, replace the ECU with a correctly coded one. For replacement of the engine control module, refer to GROUP 13A - Engine Control Module . For replacement of the SRS-ECU, refer to GROUP 52B - SRS Control Unit . For replacement of the ETACS-ECU, refer to GROUP 54A - ETACS .

OPTION CODING
caution
  • If there is any item indicated by the option coding after equipment change, set ETACS-ECU so that the option coding data corresponds with the equipment content. Pay attention to that the concerned functions and systems do not work normally if the setting does not correspond with the equipment.
  • With the ETACS functions being customized, if any of the ETACS-ECU option coding items are changed, the customized contents are reset. In such case, the functions need to be recustomized.
The ETACS-ECU option coding data can be checked or changed by operating scan tool (M.U.T.-III).
  • How to check option coding data
    1. Connect the scan tool (M.U.T.-III). Refer to .
    2. Select "ETACS" on the system selection screen.
    3. Select "Coding."
    4. Select "Option Coding Information."
    5. Check the displayed option coding information.
  • How to change option coding data
    1. Connect the scan tool (M.U.T.-III). Refer to .
    2. Select "ETACS" on the system selection screen.
    3. Select "Coding."
    4. Select "Option Coding."
    5. Change to correct option coding data.
