Replacement Of ECM And SMARTRA

In case of a defective ECM, the unit has to be replaced with a "virgin" or "neutral" ECM. All keys have to be taught to the new ECM. Keys, which are not taught to the ECM, are invalid for the new ECM (Refer to KEY TEACHING PROCEDURE ). The vehicle specific data have to be left unchanged due to the unique programming of transponder.

In case of a defective SMARTRA, there is no special procedure required. A new SMARTRA device simply replaces the old one. There are no transponder-related data stored in this device.

   NOTE:

   1. When there is only one key registered and you wish to register another key, you need to re-register the key which was already registered.
   2. When the key # 1 is registered and master key #2 is not registered, Put the key #1 in the IG/ON or the start position and remove it. The engine can be started with the unregistered key #2.

      (Note that key #2 must be used within 10 seconds of removing key #1)

   3. When the key #1 is registered and key #2 is not registered, put the unregistered master key #2 in the IG/ON or the start position.

      The engine cannot be started even with the registered key #1.

   4. When you inspect the immobilizer system, refer to the above paragraphs 1, 2 and 3.

      Always remember the 10 seconds zone.

   5. If the pin code & password are entered incorrectly on three consecutive inputs, the system will be locked for one hour.
   6. Be cautious not to overlap the transponder areas.
   7. Problems can occur at key registration or vehicle starting if the transponders should overlap.
