3. RKE FUNCTION
3.1 DOOR LOCK / UNLOCK USING TRANSMITTER
3.1.1 TRANSMITTER LOCK / UNLOCK
This system function by using two buttons of the valid Tx is shown at Table 1. Now we define
the “VALID Tx” as the ID code (Fixed code + Crypto code) of the Tx is memorized by the
Control Unit.
Status Button Function
A Unset "UNLOCK" All door unlock, Hazard lamp blink twice, Disarming Mode
B Set "LOCK" All door lock, Hazard lamp blink once, Arming Mode
[Table 1. System Function by Using Two Buttons of the Valid Tx]
When the ignition is off, the key reminder is off and all doors(door / hood / trunk) are closed,
door lock by the Tx lock button. The Rx status goes to the arming mode in the condition of the
arming mode. For the information of the remote door lock, the hazard lamp blinks once for
0.5sec and the siren operates once 0.05sec.
When remote door lock is operated and not in the condition of the arming mode, hazard lamp
does not blink and Siren does not operation because of not changing Rx status.
When the ignition is off and the key reminder is off, the Rx drives the door actuator in order to
unlock all doors by the Tx unlock button. The Rx status goes to the disarming mode. For the
information of the remote door unlock, the hazard lamp blinks twice, the period is 1sec and the
duty ratio is 0.5sec. But if there was the burglar alarm, the hazard lamp blinking period is 2s
(0.5sec On and 1.5sec Off).
