Is the communication possible between scan tool and Immobilizer system?
YES

If communication between SMARTRA and ECM is OK, Check ECM status of the current data.

If ECM status is "Lock", Please wait for one hour with IG Key "ON" and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

NOTE: Disconnecting battery or others manipulation can not reduce this time. After connecting the battery the timer starts again for one hour.

NO

Check DLC cable connection between Scanner and DLC. And, update the scan tool program card with latest version. Finally try communication between scan tool and Immobilizer system.

If problem still continues, Substitute with a known-good scan tool and check for proper operation. If the problem is corrected, and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
