Circuit / System Description
When the ignition is switched on, the antenna that is integrated in the theft deterrent control module (Immobilizer) is energized. During this period the engine control module (ECM) sends a signal to the BCM requesting the frequency code. The transponder key contains a security code (transponder code) that transmits via the antenna to the theft deterrent control module. The theft deterrent control module sends the code to the BCM. The BCM compares the received code with the stored transponder code. If the transponder code is recognized, the BCM blocks the speed signal input to the ECM allowing the transfer of the frequency code to the ECM. The ECM compares the received frequency code with the programmed frequency code. If the signal is recognized and matches the programmed signal the engine is allowed to start.
