A. INTRODUCTION

As of model year 2003, a new coding method is required in the event an engine control module or transmission control module is replaced or flashed. The emission regulations require that all codeable (emission-relevant) electronic control modules have a Software Calibration Number (SCN) which uniquely identifies the control module version installed in the vehicle. This process has been created to prevent incorrect coding of electronic control modules.

The SCN Code is comprised of a multiple digit/character coding string, an SCN and a check digit. It is created using the VIN based factory specification data for the vehicle in addition to the part number of the ECM replaced or flashed. It identifies both the control module software as well as the coding conforming to the specific vehicle.

SCN Codes will now be able to be generated by authorized dealership personnel via any computer with internet access or any NetStar Terminal. This will be possible by the user accessing a secured website utilizing a log-on and password unique to the user. The user then will be able to generate an SCN Code using vehicle data as well as data from the replaced/flashed ECM.

This revised process will be referred to as the 'office procedure' and will provide faster service for the dealership personnel. This 'office procedure' will only allow the dealer to obtain SCN Codes using a desktop PC. In order to obtain SCN Code using a networked STAR Diagnosis System, please refer to S-B- 58.00/144 .

B. PROCESS OUTLINE

The 'office procedure' specified in this SI is divided into three parts: obtaining a User ID and Password, accessing the website and installing the program on the user's computer, and generating an SCN Code.

Obtaining a User ID and Password -

In order to obtain a User ID/Password the requestor must fill out the form that is contained within this SI. This form must be approved and signed by the Service Manager and then must be faxed to MBUSA using the number provided on the form. This form will then be checked and approved by MBUSA and sent to the account administrator at DCAG. Once received by DCAG, the User account will be created and the User ID/Password will be e-mailed to the requestor directly from DCAG. This process is to ensure that only authorized personnel obtain User IDs as well as to maintain security.

Please refer to subject C for instructions on obtaining User ID and Password.

NOTE:

Each dealer may obtain as many User IDs and Passwords as they require as long as a signed form is submitted for each.
This process of obtaining a User ID/Password may take up to a week to complete depending on volume of requests.
MBUSA will retain all Registration Forms submitted via fax. However for security reasons, MBUSA will have no record of User Accounts activated by DCAG or User IDs and Passwords that are emailed from DCAG to the requestor.

Accessing the website and installing the program -

This procedure can only be performed after a User ID and Password has been obtained. The user will enter the Flash Website URL (listed in the body of this SI) into their web browser from any computer with internet access. Access is also possible from any NetStar Terminal by selecting the 'SCN Coding' menu found under the 'Service' tab. The User ID and Password will allow access to the website and by following the procedure detailed in the body of the SI the download the program will occur automatically.

Please refer to subject D for instructions on installing the 'office process' software on any PC with internet access or on your NetStar PC.
NOTE:
- Some minor PC configuration may be required in some cases, this configuration information is contained within the body of the SI.
- The program is large in size and internet/NetStar users with speeds less than 128kbps should perform the download after normal working hours to ensure that the download is successful.
- The program will automatically install the first time the website is accessed, any updates to the program will automatically install in the future

Generating an SCN Code -

This procedure can only be performed after a User ID and Password have been obtained and the 'office process' software has been downloaded. In order to obtain an SCN Code you must have the full VIN of the vehicle as well as the correct part number, MB Number or MB Object Number (number required is dependent on type of ECM) of the ECM that you wish to obtain an SCN Code for. This ECU part number, MB Number, or MB Object Number can be identified by STAR Diagnosis using the 'Control Unit Version' menu selection. Follow the procedure outlined in the body of the SI in order to obtain an SCN Code.

NOTE:

ME-SFI & NAG1 ECMs use the MB Number or the part number in order to generate an SCN Code.
722.9/NAG2 ECMs use the MB Object Number in order to generate an SCN Code.

Please refer to subject E for procedure of how to generate an SCN Coding using this application.

Technical Support -

For User ID and Password inquiries:

Please call the NETSTAR Help Desk

Phone - 1.888.9.NETSTAR

Please ensure that you have submitted a User ID Request Form prior to making contact
NOTE: The MBUSA TAC cannot assist you in regard to User ID/Password related problems

For 'office process' software download problems or for PC configuration inquires:

Phone - 1.888.9NETSTAR (07.00 - 20.00 EST)

Please ensure that you have obtained a User ID and Password before contacting. If you have not obtained a User ID and Password the helpdesk will not be able to assist you.
Please ensure that you have you User ID and Password available
NOTE: The NETSTAR help-desk cannot assist you in problems with obtaining an SCN Code
NOTE: The MBUSA TAC cannot assist you in regard to software and/or PC configuration problems

For problems or errors received while generating an SCN Code:

Please call the STAR Diagnosis Help Desk

Phone - 1.888.532.7096

Please ensure that you have you User ID and Password available
Please ensure that for all communications you have your User ID, detailed contact information including: name, dealer number, phone number, and email address as well as full vehicle VIN and any applicable ECM information (part number, MB Number, MB Object Number) ready.
NOTE: The MBUSA TAC will not fulfill requests to generate SCN Codes, they can only validate an SCN Code that you have previously generated.

For all other inquiries:

Email MBUSA - technicalinformation@mbusa.com

Please ensure that all communications contain your User ID, detailed contact information including: name, dealer number, phone number, and email address as well as full vehicle VIN and any applicable ECM information (part number, MB Number, MB Object Number)

Troubleshooting -

Cannot access account/Password not valid

Refer to Technical Support section of this SI

Cannot generate an SCN or Error message received during the generation process

Ensure that vehicle is MY2003 or newer
Ensure that VIN is correct
Ensure that ECM part number is applicable to vehicle (you may need to have your parts department contact the Part Assistance Center)
Refer to the SCN Coding FAQ posted on STAR TekInfo

STAR Diagnosis will not accept SCN Code generated

Generate the SCN a second time to validate correct number was generated
Refer to the SCN Coding FAQ posted on STAR TekInfo

After entering SCN Coding the ECM, the vehicle does not operate properly

Refer to the SCN Coding FAQ posted on STAR TekInfo
Please ensure that for all communications you have your User ID, detailed contact information including: name, dealer number, phone number, and email address as well as full vehicle VIN and any applicable ECM information (part number, MB Number, MB Object Number) ready.
