BENZ SCN coding auto diagnostic tools:
Flashing and Software Calibration Number (SCN) 2 Objectives
l Explain when, why and how flashing is performed
l Explain when why and how SCN coding is performed
Flashing and Software Calibration Number (SCN) 2 Objectives
l Explain when, why and how flashing is performed
l Explain when why and how SCN coding is performed
At the end of this presentation the participants will be able to: Introduction Flashing is a way to update control unit software l Flashing is required
-If DTB requires updating of software
- Requested by TAC/EDAC
-New ECU part number
SCN coding identifies control unit software and coding conforming to Vehicle l SCN is required
After flashing fuel control unit (ME) or Electronic Transmission Controller (ETC)
After replacement of ME or ETC
-Required by law, can be fined if not done
- Vehicle may not function correctly if not performed
-Prevents after-market performance enhancements
- In future additional control modules will require SCN coding
Flashing
l Flashing is performed using SDS
-Via CD in SDS
-DAS (software updates)
-Via on-line (near future)
l SDS downloads software into appropriate control unit
l Flashing is only to be performed when needed, otherwise issues may arise
Note: Keep battery charger connected to vehicle during flash, battery voltage critical to process, verify proper connection to X11/4 Software Calibration Number
SCN l As of 2003 emission regulations require SCN in all coded emission related control units
l SCN identifies control unit software and coding for a specific vehicle (similar to version coding) --Coding string adapts the control unit to the individual vehicle, incorporates vehicle equipment, safety information and emissions
--Check digit also referred to as test digit checks VIN, SCN and code string
l Must get new SCN when replacing or flashing ME or new Transmission control units
l If improperly completed certain features of vehicle may become inoperative (Tip start, cruise control)
SCN Coding Process
l Receive SCN coding from Via E-mail or SDS help desk
l Information needed
-Your name
-Your E-mail address
-Dealer name and number
- Part# for ME or Transmission control module
-VIN
l Information returned via e-mail
-SCN coding (example 1131531279
- Code string (example 08-7D-08-&D- 52-14-2C)
l Note: make sure to use code string as
- Test digit (example 1A-0C-9D-43)
l DAS in ME --Control Unit Adaptations SCN Coding / Perform SCN Coding Note: Process will change SCN Coding Process
- Vehicle may not function correctly if not performed
-Prevents after-market performance enhancements
- In future additional control modules will require SCN coding
