How to Perform Vehicle Identification Number (VIN) Writing

HOW TO PERFORM VEHICLE IDENTIFICATION NUMBER (VIN) WRITING

CAUTION:
The F.A.S.T-Key (Free-hand Advanced Security Transmitter) is described as the Keyless Operation System (KOS) in this manual. (KOS is indicated as F.A.S.T. in the scan tool display.)


Follow the procedure below to register the VIN of the Wireless Control Module (WCM) and the Keyless Operation System (KOS).
The VIN is stored in the engine control module (ECM), WCM, and the KOS-ECU. If the VIN is improperly erased, the engine warning light or the keyless operation system warning indicator illuminate, and the diagnostic trouble code is displayed. When the ECM, WCM, and the KOS-ECU are replaced, follow the procedure below to write the VIN.





WRITING PROCEDURE

Required Special Tools:
^ MB991958: Scan Tool (M.U.T.-III Sub Assembly)

CAUTION:
Check that diagnostic trouble code P0603 "EEPROM fail" is not set. When diagnostic trouble code P0603 "EEPROM fail" is set, the ECM cannot store the key code even if the key code is registered.

CODING LIST

CAUTION:
With 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, TC-SST-ECU and ETACS-ECU are normal. If they are not the same as the initial settings, various functions and systems will not work correctly.
