Objectives 目的
l Explain when, why and how flashing is performed 哪种情况下需要软件编程
l Explain when, why and how SCN coding is performed 哪种情况下需要SCN DOING
At the end of this presentation the participants will be able to:
Introduction
Flashing is a way to update control unit software 编程是升级控制单元软件的一种方法
l Flashing is required 如下状态需要编程
– 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
奔驰722.9自动变速箱进入紧急模式
        涉及车型：w171/w203/w209/w211/w219/使用７２２．９自动变速箱／M272型发动机／车型年代码８０６和变速箱控制模块软件版本为００１４４８５４１０或００１４４８６９１０或００１４４８８３１０或００１４４８８４１０或００１４４８８５１０的车辆．
  故障现象：使用变速箱控制模块软件为以上版本的车辆，自动变速箱进入紧急模式，并且有一个或两个以上的P1629. P1632. P1633. P1634. P1636的故障码．
  故障原因：使用以上版本的车辆会因蓄电池电压太低（如发动机启动时）而产生故障码和造成自动变速箱进入紧急模式．

  解决方法：若车辆使用上述自动变速箱控制模块的版本，则不需要依照诊断仪ＤＡＳ的相关说明执行这些故障码的维修处理（不用更换电子液压控制阀体总成），仅需要完整执行下列的维修处理流程：  １．使用诊断仪ＤＡＳ重新执行自动变速箱控制模块的程序设定（Ｐrogrmming)(诊断ＤＡＳ的软件必须是ＤＶＤ０９／２００５或更新的软件版本）．２．执行SCNcoding. ３．删除故障记忆．
