General Description

A transponder is incorporated in the head section of the key. The antenna coil supplies energy to the transponder. The transponder accumulates energy in the condenser. Once the energy supply from the coil has stopped, using the stored energy in the condenser, the transponder transmits the ID CODE (stored within the ASIC).
When Ignition is set 'ON' the ICM receives a request signal from the ECM and starts ID Code registering sequence. If the ID code format from the transponder is not correct, the ICM repeatedly performs the registering sequence.
When the correct ID code format is registered, the code is verified by the ICM. If the code is not verified, the registering sequence is repeated a maximum of 5 times which is equivalent to 1 second duration.
Once the correct ID code is registered and verified after Ignition is turned ON, the registering sequence is not reperformed until Ignition is turned OFF.
