SERVICE
Tip: The "Pass-Thru Vehicle Programming" process may overwrite any "TUNED" ECM/TCM programming .
A "TUNED" ECM or TCM is described as any ECM or TCM altered so as to perform outside the normal parameters and specifications approved by Volkswagen of America, Inc. .
If you encounter a vehicle with a "Tuned" ECM or TCM, prior to performing the "Pass-Thru Vehicle Programming" procedure:
- Your Service Center should place the vehicle owner on notice in writing, that their ECM or TCM was found to have been tuned, and that any damage caused by the tuning of the ECM or TCM (including any adverse emissions consequences) will not be covered by Volkswagen of America, Inc. warranties.
- For any repair requested by the owner under warranty or outside warranty that requires Pass-Thru Vehicle Programming, which will automatically wipe out the "Tuning" program, your Service Center should advise the owner of the above and get Owner's written consent (see attached Control Module Tuning form) to the flashing procedure.
VEHICLE REQUIREMENTS
- Battery MUST have minimum no-load charge of 12.5V (failure to maintain voltage during update process can lead to ECM/TCM failure)
- Battery voltage must be maintained throughout procedure (always use an approved battery Charger/Maintainer).
- Any appliances with high electromagnetic radiation (i.e. mobile phones) switched OFF.
- No Stored DTCs, erase any stored DTCs.
TOOL REQUIREMENTS
- Pass-Thru Vehicle Programming tool must be connected to the vehicle Data Link Connector (DLC) and is connected to an Internet connection (Persistent connection is recommended).
- Approved Battery charger.
NOTE:
Under no circumstances should the diagnostic connector or the Programming tool be unplugged during the Pass-Thru Vehicle Programming procedure (damage to the ECM/TCM can occur).
Any appliances with high electromagnetic radiation (i.e. mobile phones) must be switched OFF.
PROCEDURE
- Click on "Continue" to proceed and follow the prompts to update ECM to the software level listed below:
