SVM Update Instructions
1. If you encounter a vehicle with a tuned ECM or TCM, your dealership must do the following before performing any procedure that updates ECM or TCM programming:
NOTE:
Any Update Programming procedure (flash) may overwrite any tuned ECM or 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 Audi of America, Inc.
a. Notify the owner that their ECM or TCM was found to have been tuned.
b. Notify the owner that any damage caused by the tuning of the ECM or TCM (including any adverse emissions consequences) will not be covered by Audi of America, Inc. warranties.
c. Obtain the owner's written consent (see Control Module Tuning form) for any requested repair - under warranty or outside warranty - that requires flashing that will automatically overwrite the tuned program.
2. Check the software part number and software level in the Engine Control Module (J623).
3. Prior to beginning the SVM process, insert a USB memory stick into the VAS 5051 tester to capture the diagnostic log electronically.
4. Connect the VAS 5051A and VAS 5051B to a 110 V AC power supply. The VAS 5051A and VAS 5051B must be connected to 110 V AC power supply at all times during the procedure.
5. Update the Engine Control Module (J623) using SVM action code as listed in the table below if necessary. If the vehicle has a tuned ECM or TCM, ensure the Control Module Tuning form has been filled out by the owner.
Tip:
The SVM Process must be completed in its entirety so the database receives the update confirmation response. A warranty claim may not be reimbursed if there is no confirmation response to support the claim.
- After updating the programming of the ECM, it is not necessary to set the Readiness Code.
For further SVM update instructions and troubleshooting, please refer to the SVM Operating Manual; ElsaWeb TSB 2011732.
