will prevent the car from running without a matching key microchip. There
is a symbol in the instrument cluster showing a key inside a car. If a new
(or different ECU) is installed in the vehicle, the immobilizer will
prevent the car from running and will cause the symbol to flash. Here is
the procedure to introduce a new ECU to the instrument cluster. This must
be performed each time ECU's are exchanged. This does not apply to
installing a "chip" in the same ECU that is already aligned with the car.
Immo-3 knows your car's VIN.
Access 17-Instruments (or separate 25-Immobilizer on vehicles that are set
up that way) and look at the first "Extra" field.
If you see something like: "Immo-ID VWZ7Z0W0648696" You've got
Immo-2 (or maybe even Immo-1 in earlier non-US models).
If you see something like "WVZKB58001H231169 VWZ7Z0W0648696" You've got
Immo-3. The first 17-digit string is the VIN. The second 14-digit string
in the Immo-ID.
Install the new ECU in the car
[17 - Instruments]
[Adaptation - 10]
Leave channel at "00"
[Done, Go Back]
[Close Controller, Go Back - 06]
Turn ignition OFF for 15 seconds.
Note: For cars with a
separate Immobilizer (Includes 2000+ EuroVan, Cabrio, and many older
non-US models), use [25
Immobilizer] instead of
[17 - Instruments]. The rest of the procedure is the same.
