Back to i-flash updates

 

In order to determine if a vehicle needs a software flash update, some manufacturers have provided a mechanism on their websites to do this without purchasing a subscription.  Here, we provide instruction on how to do this with the manufactures Parts World’s J2534 tool supports.

 

 

Chrysler/Dodge/Eagle/Jeep/Plymouth

 

  • You need to get the current calibration ID from the vehicle using your scan tool.
  • Once you get that number, click the following link to open a PDF file. (click here)
  • Search the table to find the calibration ID that you pulled from the vehicle.
  • Compare the letters following the calibration ID.  If the letters are after those found in the vehicle, the vehicle needs an update.  Example; if the Cal ID is 56040409AA, and you find it in the table as 56040409AC, you need to purchase the update.
  • This information is on the manufacturer’s website; however, you must log in to find it.  The short-cut link above is the same information you would receive if you were to log in to the site.
  • This site does not indicate what symptoms are being corrected.

 

 

Ford/Lincoln/Mercury

 

  • You need to get the current calibration ID from the vehicle using your scan tool
  • The following link takes you to a Motorcraft website.  (click here)
  • Click on the latest calibration information link.
  • At the bottom of the sample table, there is a link to Search Calibration by Vehicle, Model Year and Engine.  Click on this link.
  • Enter the year make model information.  A table will open listing calibration ID’s.  Compare the CALID taken from the vehicle.  If that number is not on the list, it is not up-to-date
  • There is an alternate way to check that is very cumbersome.  This new way to check is much easier.
  • This site does not indicate what symptoms are being corrected.

 

 

General Motors

 

  • You need to get the current calibration ID from the vehicle using your scan tool.
  • Get the vehicle’s VIN number.
  • Go to the GM website by clicking on the link provided or from our I-Flash page. (click here)
  • Enter the VIN in the space provided.
  • There will be a list of Cal ID numbers listed.  Compare these to those taken from your vehicle.  If the website lists higher numbers than what are in the vehicle, there is an update.
  • GM also provides a short description of each update.  This may help determine if you are encountering any of the symptoms the flash is correcting.
  • No subscription is needed to get this information.

 

 

Nissan/Infinity

 

  • You need to get the current calibration ID from the vehicle using your scan tool.
  • Follow the link provided to go directly to the correct page. (click here)
  • There are two dropdown boxes to select.  The first one provides data for all OBDII systems.  The second is all calibrations that can be updated with your J2534 interface tool, 2004 and newer.
  • Find the calibration ID from the menu.  Double click it.  A new page will open with the ID in a small window.  Old ECM or TCM # will show the selected code.  Under it will be a new ECM or TCM #.  If the number is higher, there is an update.  If the number is the same, your vehicle has the most up-to-date calibration information.
  • This site does not indicate what symptoms are being corrected.

 

 

Honda/Acura

 

  • The annual subscription is required to get the updates for J2534 PCM initialization software.
  • Helm is the vendor Honda uses to distribute their information.  Contact them at 949-330-7152 to check for updates for any specific vehicle.
  • Very Important.  Honda PCM initialization software will not work on Windows XP Home Edition.  Check the provided link for up-to-date system requirements for J2534 pass-through devices.  ((click here) go to Tools Info tab)

 

 

Toyota/Lexus/Scion

 

  • There is no facility to check calibration ID information on the manufacturer’s website.  You must obtain a current CD from the manufacturer.  This can be obtained by ordering it on Toyota’s site.  (click here)

 

 

As more information is available, it will be posted here.  Check back soon.
