Introduction

SCN Coding and CVN Generation

CVN Redocumentation - Back-up Process

A. INTRODUCTION

As of model year 2005, a new coding method is required in the event an engine control module or transmission control module is replaced or flashed. The applicable emission regulations require that all codeable (emission-relevant) electronic control modules have a Calibration Verification Number (CVN) which uniquely identifies the control module version installed in the vehicle.

The Calibration Verification Number (CVN) is an 8 character long string and is accompanied by 8 character long check digit. The Calibration Verification Number CVN is automatically generated by the engine or transmission control module after it has been replaced or flashed and has been subsequently SCN Coded.

Once the Calibration Verification Number (CVN) has been generated, it then must be reported back to DaimlerChrysler in a process called "Redocumentation". The "Redocumentation" of the CVN and check digit is performed via the same Office application currently used to generate SCN Codes. This "Redocumentation" process has been created to ensure the proper reporting of each control module version so that DaimlerChrysler can maintain proper records as well as report the data to the Federal Government.

NOTE: For information on how to access the SCN Coding Office Application please refer to S-B-07.61/38H .

B. PROCESS OVERVIEW

The CVN Redocumentation Process specified in this Service Bulletin is divided into three parts: SCN Coding and CVN Generation, CVN Redocumentation - Primary Process, and CVN Redocumentation - Back-Up Process.

SCN Coding and CVN Generation -

In order to generate a CVN, the control unit must first be SCN Coded. The SCN Coding process is outlined within this Service Bulletin in Section C. After SCN Coding, the control unit will automatically generate the CVN and Check Digit [3] which then must be redocumented using the procedure outlined in Section D.

NOTE: Failure to redocument the CVN immediately after SCN Coding (using the CVN Redocumentation - Primary Process outlined in Section D) will result in a pop-up message on the STAR Diagnosis System screen noting that there are vehicles that have not had their CVN redocumented. In addition to the pop-up message, a screen will be displayed showing the VIN and pertinent information of the vehicles that have not had their CVN redocumented. This pop-up message and vehicle record screen will be displayed every time the DAS application is used until the CVN that have not been redocumented are redocumented.

CVN Redocumentation - Primary Process -

This process will allow the user to simply print out the CVN and Check Digit [3] and redocument them utilizing the familiar SCN Coding Office Application. Once the CVN and Check Digit [3] have been redocumented, the SCN Coding Office Application will generate a Release Code and Check Digit [4] to confirm to the user that the redocumentation was successful. This Release Code and Check Digit [4] then must be input into the STAR Diagnosis System in order to prove that redocumentation has successfully occurred.

NOTE: For information on how to access the SCN Coding Office Application please refer to S-B-07.61/38H .

CVN Redocumentation - Back-Up Process -

NOTE: This process should only be used if it was not possible to redocument the CVN and Check Digit [3] at the time of SCN Coding.

In order to properly redocument, the VIN, CVN and Check Digit [3] must be determined as outlined in Section E. Once the VIN, CVN and Check Digit [3] have been obtained the user then must perform the Redocumentation utilizing the familiar SCN Coding Office Application. After the CVN and Check Digit [3] have been redocumented, the SCN Coding Office Application will generate a Release Code and Check Digit [4] to confirm to the user that the Redocumentation was successful. This Release Code and Check Digit [4] then must be input into the STAR Diagnosis System in order to prove that Redocumentation has successfully occurred.

NOTE: Failure to input the Release Code and Check Digit [4] into the STAR Diagnosis System will result in a pop-up message on the STAR Diagnosis screen noting that there are vehicles that have not had their CVN redocumented. In addition to the pop-up message, a screen will be displayed showing the VIN and pertinent information of the vehicles that have not had their CVN redocumented. This pop-up message and vehicle records screen will be displayed every time the DAS application is used until the CVN that have not been redocumented are redocumented.

Retrieve SCN Code
NOTE: For instructions on retrieving an SCN Code using the Office SCN Coding Application please refer to S-B-07.61/38H .
Perform SCN Coding - Select 'Perform SCN Coding', Press 'F3'. (Fig 3)

Fig 3: Performing SCN Coding
Input SCN Code, then Press 'F3' (Fig 4)
NOTE: Please be sure to input all of the characters of the SCN Code that you have retrieved including any sets of zeros (00).

After the SCN Coding process, the CVN is automatically read out of the ECM. The calculation of the CVN may take up to 180 seconds. (Fig 7)

Fig 7: CVN Calculation
The CVN and Check Digit [3] are displayed on the SDS Screen. Press 'F11' to print out the CVN and Check Digit [3]. (Fig 8)

Fig 8: Printing CVN And Check Digit

The CVN must now be redocumented.

NOTE: If the CVN is to be redocumented at this time please proceed to Section D.

[CVN Redocumentation - Primary procedure]

NOTE: If the CVN is to be redocumented at a later date please proceed to Section E.

[CVN Redocumentation - Back-up procedure]

NOTE: The SCN Coding process is complete at this stage and the vehicle can be released.

NOTE: If the ME Control unit has been replaced, drive authorization may need to be performed.
