Important
After successful programming, the engine control can only be used for vehicles with immobilizer and transponder.
Faults that occur in connection with the immobilizer control unit are recognized by the engine control unit and as
long as “IMMOBILIZER” is not programmed, are indicated by a flashing of the engine check light.
The DDS-1 unit can be reprogrammed and takes around 10 minutes for Tech 2 to complete.

Loss of car pass
If the car pass is lost, the data can be requested from your proper organization name. This request will only be
processed if accompanied by the enclosed form and proof of ownership.
Once the data is received, it can be entered in a blank car pass and given to the customer. The unused car pass
should be destroyed.
Instructions on Filling Out the form "Data request, car pass"
To be provided by the dealership
The data requested under items 1-10 must be provided completely, including the authorized
dealership number, the vehicle identification, number(VIN) and engine type/number (Engine type/No.)
Mark missing data / desired data with a cross:
19. Security code (for diagnosis and programming with Tech 2)
20. Mechanical Key Number
Complete the form by entering the data and signature/authorized dealership stamp and send it along with
proof of ownership (Vehicle lD or invoice) to address provided in the form. The requested data will be sent
by Fax to the dealership that made the request after your organization has confirmed that the info is
corrected.
Important Instructions:
Only data corresponding to the delivery status of the vehicle can be issued. Car pass data requests will only
be processed if the first column is filled out completely, signed and sent to your organization along with
proof of ownership.
Information via telephone is only possible in exceptional circumstances via your service organization.
As for the delivery of new vehicles, the customer must be informed about all features of the car pass that are
relevant to vehicle security, for example, that the car pass should be kept in a safe place (not in the vehicle) and
should be presented when an authorized your organization name workshop is visited. The exact phrasing can
be found in the relevant Owner's Manual.
