When the ignition is switched on and an attempt made to start the engine the ECM sends an unlock request to the immobilizer control module. The immobilizer control module outputs a 100-150kHz carrier wave to the antenna ring. This signal is induced into the transponder. The transponder responds to this induced signal by outputing the key code identification which is transmitted back to the immobilizer control module via the antenna ring. This key code identification is then compared with the stored code in the immobilizer control module memory. At this point the immobilizer control module only recognizes this as one of a series of registered keys. To further increase security, the immobilizer control module transmits a random code to the ECM and the key transponder and requests an algorithmic calculation to be performed. The immobilizer control module also performed. The immobilizer control module also performs this algorithmic calculation independently. The ECM and key transponder return the answers of the algorithmic calculation to the immobilizer control module. A comparison is made and if they match, the unlock request is granted. If any of the calculations do not match the unlock request is denied, the engine will not start or, if already started, will stop. This authentication procedure happens so quickly that the driver may only be aware of a very slight delay between the key being turned and the engine starting. The immobilizer system is automatically reset when the ignition is switched off and the key withdrawn from the ignition switch. Many immobilizer systems feature fault memories which can be accessed in various ways e.g. by counting immobilizer warning lamp flashed, bridging data link connector (DLC) terminals with voltmeter or LED tester, or using suitable diagnostic equipment.
