Description

1 If the ETACS receives the “Lock” signal from TX.( when IG key removed from key cylinder and all switchs are closed)

ETACS outputs “ON” the “Lock” outputs and vehicle becomes “Armed condition” with turn on the Hazard

lamp for 1 sec After confirming lock signal of door lock actuator.

2.If the ETACS receives the “Lock “ signal from TX when any one switch of all door switches is open, it outputs “ON” the “Lock” output only,

In this case, ETACS does not output Hazard lamp “ON” and the vehicle does not “Armed”

3 The door is closed in the above “2” condition, ETACS output “ON” the Hazard lamp for 1sec And the vehicle is Armed.

4 If lock button on the TX is pushed again under “Armed” condition, only Hazard lamp is “ON” for 1sec With maintaining Armed condition.

☞ Only the TX can make the “Armed” condition for the vehicle.
