Flashing and Software Calibration Number (SCN) Introduction Flashing is a way to update control unit software ** 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 ** 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 ** Flashing is performed using SDS – Via CD in SDS – DAS (software updates) – Via on- Line (near future) [color=Red]What we supplied [/ Color] ** SDS downloads software into appropriate control unit ** 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 ** As of 2003 emission regulations require SCN in all coded emission related control units ** 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 ** Must get new SCN when replacing or flashing ME or new Transmission control units ** If improperly completed certain features of vehicle may become inoperative (Tip start, Ruise control) SCN Coding Process ** Receive SCN coding from Via E- Mail or SDS help desk ** Information needed – Your name – Your E- Mail address – Dealer name and number – Part# for ME or Transmission control module – VIN ** Information returned via e- Mail – SCN coding (example 1131531279- – Code string (example 08- 7D- 08- & D- 52- 14- 2C) ** Note: Make sure to use code string as – Test digit (example 1A- 0C- 9D- 43) ** DAS in ME – Control Unit Adaptations SCN Coding / Perform SCN Coding Note: Process will change SCN Coding Process
