It is not convenient to get scn coding account once for once, now usb dongle with account for a whole year are in the market now.

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
