INTRODUCTION
IGNITION KEY REMINDER BUZZER <VEHICLES FOR HONG KONG SPEC. AND GCC>
The ignition key reminder buzzer will sound under the following condition, and warn the driver to remove the ignition key. The driver's door is opened when the ignition switch is at "LOCK" (OFF) or "ACC" position without removing the ignition key. However, the lamp reminder buzzer will take precedence over this function.
DOOR LOCK PREVENTION FUNCTION
If the key is left in the ignition switch while the driver’s door opened or the assistant door opened, all door are automatically unlock to prevent locking the ignition key in the vehicle after door is locked.
IMMOBILIZER SYSTEM <VEHICLES FOR SOUTH AFRICA, GCC, AUSTRALIA AND NEW ZEALAND>
The immobilizer system consists of the ignition key, the immobilizer-ECU with key ring antenna, and the engine-A/T-ECU. The ignition key has a built-in transponder. Only the registered ignition key permits the engine to start, therefore, the engine can never be started by means of a forged key or by connecting the ignition wiring directly. The system is significantly safe and reliable against theft. In addition, the driver has only to turn the ignition switch to the "ON" position to activate the immobilizer system. If the requirements for starting the engine are not satisfied, the engine will be immobilized. If a registered ignition key is lost, all your ignition keys need to be registered again using MUT-II/III to ensure security (Refer to ). An additional ignition key can be registered as follows (only if no ignition keys are lost): Using MUT-II/III (Refer to ).
OPERATION When the ignition switch is turned to "ON" position, the engine-A/T-ECU sends a requirement for the encrypted code to the immobilizer-ECU (at this time, the engine is remobilized). When the immobilizer-ECU receives the requirement from the engine-A/T-ECU, the immobilizer-ECU supplies power to the transponder inside the ignition key via the antenna. The energized transponder sends the encrypted code back to the immobilizer-ECU via the antenna. The immobilizer-ECU judges the encrypted code with its code logic in itself. If they are identical, the immobilizer-ECU sends the encrypted code to the engine-A/T-ECU. If the engine-A/T-ECU can not receive the encrypted code, the engine will be immobilized.
