IGNITION SWITCH GENERAL DESCRIPTION < UP TO DECEMBER 2003 > IGNITION KEY REMINDER TONE ALARM The ignition key reminder tone alarm 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 light reminder tone alarm 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 The immobilizer system consists of the ignition key, the immobilizer-ECU with key
ring antenna, and the PCM. 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 scan tool MB991958 (MUT-III Sub Assembly) to ensure
security (Refer to ON
-VEHICLE SERVICE
). An additional ignition key can be
registered as follows (only if no ignition keys are lost):
Using scan tool MB991958 (MUT-III Sub Assembly) (Refer to ON
