Objectives
l Explain when, why and how flashing is On performed
l Explain when, why and how the SCN coding is On performed
At the end of this presentation the participants will be able to:

Introduction
Flashing is a way a way to update control unit software programming the upgrade control unit software
l Flashing is required as follows state requires programming
- 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
Mercedes-Benz 722.9 automatic transmission into emergency mode
The involved models: w171/w203/w209/w211/w219 / use 722.9 automatic transmissions / M272 type engine / model year code 806 and gearbox
control module software version 0014485410 or 0014486910 or 0014488310 or 0014488410 or 0014488510 vehicle .
Failure phenomenon: the transmission control module software for the above versions vehicles, the automatic transmission into emergency
mode, and there are more than one or two P1629 P1632. P1633. P1634 P1636 The fault code.
Failure reasons: the use of the above vehicles due to the battery voltage is too low (such as when starting the engine) and a fault code and cause
the automatic transmission into emergency mode.
Solution: If the vehicle using the automatic transmission control module version, you do not need to be performed in accordance with the
instructions of the diagnostic DAS fault code maintenance treatment (without replacement of electro-hydraulic control valve assembly), only need to complete the implementation of the following repair process: 1. Diagnostic DAS re-implementation of the automatic transmission control module programmed (Progrmming) (diagnostic DAS software must be DVD09/2005 or
update software version). 2. The execution SCNcoding 3. Delete fault memory
