Service
ServiceRequirements:
Vehicle must meet ALL of the following criteria:
VIN must show (24M2/O3) code open in ElsaWeb on the day of repair.
Vehicle must be within the Limited New Vehicle Warranty.
Update must be performed prior to expiration date listed in this technical bulletin.
Tip:
Procedure must also be performed on applicable vehicles in dealer inventory.
PROCEDURE:
Engine and Transmission Control Module Update - Programming (Flashing) Using Software Version Management (SVM)
Vehicle requirements:
MUST have minimum no-load charge of 12.5V (failure to maintain voltage during update process can lead to ECM failure) (use a Volkswagen approved Midtronics/InCharge 940 (INC-940) tester/charger to maintain battery voltage).
VAS 5051: connected to vehicle and to 110V AC Power supply at all times during procedure.
VAS 5052: connected to vehicle with battery voltage requirements met. Any appliances with high electromagnetic radiation (i.e. mobile phones) switched OFF.
When performing the update programming procedure, ALL DTCs for all systems are erased.
DTCs linked to Guided Fault Finding function tests will be lost. Therefore, always address stored DTCs for Customer concerns unrelated to the update programming procedure first.
Note:
Non-observance of the following points may lead to ECM failure!
^ VAS 5051 or VAS 5052 must always be connected to the approved power supply at the approved voltages.
^ Under no circumstances should the power supply be interrupted or the diagnostic connector unplugged during the update programming procedure.
^ Any appliances with high electromagnetic radiation (i.e. mobile phones) must be switched OFF.
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. For further update instructions and troubleshooting, refer to SVM Technical Bulletin Instance 2014603, in ElsaWeb.
Update the Engine Control Module and/or Transmission Control Module using the Software Version Management (SVM) and the SVM Unit code as listed in the table above.
NOTE:
It may be possible to set a communication fault in the parking brake module that will not be erased by Compiling Services. If this occurs, remove ignition key for one minute and then cycle key on and clear fault.
Perform basic settings for Intake Flap Motor -V157-.
If basic settings for Intake Flap Motor -V157- cannot be performed successfully, replace Intake Flap Motor -V157-.
If one or more of the DTCs listed in the Condition section are stored in ECM data memory and ECM software was previously updated (the ECM already has the new software version), replace Intake Flap Motor -V157- even if basic settings can be performed successfully.
When performing Update Programming procedure, ALL DTCs for all systems are erased. DTCs linked to Guided Fault Finding function tests will be lost. Therefore, always address stored DTCs for Customer concerns unrelated to the update programming procedure first.
"Update - Programming" (flashing) process 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 Volkswagen of America, Inc.
If you encounter a vehicle with a "Tuned" ECM or TCM, prior to performing the "Update - Programming" (flashing) procedure:
Your dealership 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 update programming, which will automatically wipe out the "Tuning" program, your Dealership should advise the owner of the above
and get Owner's written consent (see Control Module Tuning form shown above) to the update programming procedure.
