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.

INTRODUCTION TO IMMOBILIZER SYSTEM DIAGNOSIS

CAUTION: The encrypted code should always be re-registered when replacing the ETACS-ECU (immobilizer-ECU).

The immobilizer system consists of the ETACS-ECU (immobilizer-EGU), powertrain control module, ignition key and ignition key ring antenna. If the engine cannot be started by using the ignition key, one of these components may be defective. If the immobilizer system has immobilized the engine, MFI system DTC P0513 will be set. In this case, follow the immobilizer system troubleshooting.
