Encrypted Code Registration Criteria Table

CAUTION: Do not replace the powertrain control module and the ETACS-ECU simultaneously. Always replace either one of the ECUs first, and register the encrypted code. Then, replace the other ECU.

The ignition key contains a transponder (small transmitter), which retains an unique encrypted code. When replacing the parts of the immobilizer system, always register the encrypted code or VIN, or both of them according to the list below. The ETACS-ECU can retain a maximum of eight different encrypted codes. This means that a maximum of eight ignition keys can be registered.
