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

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

Diagnostic procedure
System guidance
Engine does not run when any Diagnostic Trouble Code (DTC) is flagged, starting from 01MY TFR/S.
Once the cause of DTC is repaired or gone, engine can be operated normally, and present DTC becomes
history code.
History code is canceled by no repeat failure on 25 consequence ignition key On afterward.
History code cannot be canceled by battery connector disconnected, starting from 01MY

Diagnostic procedure
No DTC indicates
Engine does not start to run even though all engine and electrical system are OK, and no DTC appears.
1. 12V power is not supplied to ICU.
Check engine light

supplied to ICU
Repair 12V circuitICU power supply turns off when both +B line
and ignition switch line turn off.

2. Engine does not start after steering assembly is repaired.
Check if connector for Antenna coil circuit at steering shaft is correct, or missing connection.
If not correct, replace the steering assy with corrector.
3. If engine does not start after ICU replacement, check part number (01MY).
