VW Passat (3C) Immobilizer

Replacement

This model uses Immobilizer Generation 4D which is integrated as part of the Comfort Control Module (J393). At the present time VCDS can only provide limited support for this Immobilizer Generation. Unless you ALREADY have the SKC information for your vehicle and components, you will NOT be able to perform any of the Immobilizer functions.

Special Notes

• If the Ignition will not power on the Instrument cluster and CAN Gateway for communication after a new J764 is installed, hold the high beam stalk in the flash to pass position. Turning the 4-way flashers (hazards) ON is another method that applies to Mk5/6 era VWs when CAN communication needs to be forced to match new Immobilizer components.
• If the replacement J764 ESCL will not match make sure MVB group 081 contains the VIN to the vehicle and confirm group 123 contains all XX'es. If a VIN is shown in group 123 the ESCL was already matched. Used ESCLs canNOT be re-matched to another vehicle.
