Keyless operation key (incorporates
emergency key)
⦆
The keyless operation key receives signals sent from each
interior/exterior transmitter antenna, certifies the keyless
operation key ID code, calculates the encrypted code, and
sends the reply data signal to KOS-ECU via the receiver
antenna module. When the lock/unlock switch on the keyless
operation key is pressed, corresponding signal is sent to KOS-
ECU via the receiver antenna module.
⦆
If two or more keyless operation keys registered in KOS-ECU
respond at the same time, their signals would interfere. To
avoid this interference, each signal from KOS-ECU is given
the priority*1data, and the keyless operation keys respond in
accordance with this priority.
