wiTECH "New Flash Available" Icon Functionality

Article ID: 195
Last updated: 15 Oct, 2013


  • The purpose of this article is to explain the "New Flash Available" icon's functionality and how it relates to service documentation (Service Bulletins, Safety Recalls, and Rapid Response Transmittals).
  • The wiTECH system does additional filtering to only enable the "New Flash Available" icon if the associated service documentation (Recalls, Service Bulletins, and RRTs) applies to the connected vehicle.
    • Even with this feature, it is still critical to read the associated service documentation!
  • It is important to note, however, that even though additional filtering is being done, you may see a flash update is available under the wiTECH ECU Flash tab but the New Flash Available icon is NOT illuminated. 
    • This implies that a flash is available purely based on the ECU part number. 
    • Though the flash update is available, it most likely DOES NOT apply to the connected vehicle. 
    • In these cases, you should not perform the flash unless specifically instructed to do so via service documentation.


Service Bulletins

  • Service Bulletins generally apply to vehicle attributes such as sales codes, engine, build date, model year, and body.
    • These attributes are used to determine the "New Flash Available" icon behavior.
    • Example: An ECU has an update that applies to all the attributes above; in this case the flash update icon would be displayed prompting the user to update the ECU.
      • If the vehicle has Service Bulletin attributes that do not apply, the "New Flash Available" icon will not be displayed.
  • If ECU updates apply by s/w part number applicability (e.g. 12345678AA --> 12345678AB) and no Service Bulletin exists for the particular update, the "New Flash Available" icon will be displayed.
    • This is required because this ECU could be a PCM that was replaced and has to be reprogrammed after replacement (sometimes reffered to as a generic PCM).  
  • If a Service Bulletin applies to a vehicle based on the attributes (sales code, build date, etc.) and the ECU is already at the latest part number level, the "New Flash Available" icon will not be presented.

Safety Recalls and Rapid Response Transmittals (RRTs)

  • Safety Recalls and RRTs are vehicle identification number (VIN)-driven and only apply to vehicles based on the vehicle's VIN.
    • The wiTECH Diagnostic Application uses VIN association filtering for the "New Flash Available" icon.
    • If a Safety Bulletin or RRT applies to a vehicle based on its VIN and the ECU is not at the latest part number level, the "New Flash Available" icon will be displayed.
  • If an ECU update is available and a Safety Recall or RRT does not apply to the VIN of the connected vehicle, the "New Flash Available" icon will not be displayed.
  • If the ECU is up-to-date (indicating that the ECU was flashed previously) and a Safety Recall or RRT applies to the VIN, the "New Flash Available" icon will not be displayed.

Generic ECUs

  • When a generic ECU is installed on a vehicle, the wiTECH Diagnostic Application will search for available flash files based on the vehicle's VIN, then check the supercedence for a match based on generic part number.
    • If there is a match and no service documentation applies, the "New Flash Available" icon will be displayed.
  • If a generic ECU is installed on a vehicle and there is service documentation referencing this flash file update but the attributes do not apply to the connected vehicle, the "New Flash Available" icon will not be displayed.
  • If an incorrect generic ECU is installed and no match can be found with the flash files available by VIN all flash files based on the generic part number supercedence will be displayed.


NOTE: If multiple files are displayed when a generic ECU is installed, check the generic ECU part number for vehicle applicability; ECU replacement will be required if flashing with an incorrect calibration.

Multiple Flash Updates

  • In some circumstances there are multiple flash files that can be included in an ECU's part number supercedence.
    • In this scenario, if the ECU is up to date and has a match with any displayed flash file part numbers, the "New Flash Available" icon will not be displayed.
  • If the ECU has multiple flash files that apply by part number supercedence, the ECU is not up to date, and service documentation attributes apply, the "New Flash Available" icon will be displayed.
  • If the ECU has multiple flash files that apply by part number supercedence, the ECU is not up to date, and no service documentation applies, the "New Flash Available" icon will be displayed.
