KEYLESS ENTRY SYSTEM

BODY

• If none of the doors is opened or the ignition key

is not inserted in the ignition switch within 30 sec-
onds after the doors are unlocked using the
transmitter, the ETACS-ECU will relock the doors
automatically. This is called "Timer lock function."
This timer lock function prevents accidental
unlocking of doors. The adjustment function
allows you to change the timer lock period from

30 seconds (default setting) to 60, 120 or 180
seconds. For further details on using the
multi-center display (middle grade type) to adjust
the timer lock period, refer to GROUP 54B,
On-vehicle Service

P.54B-486

NOTE: The timer lock period begins when the doors
are unlocked, and ends when the doors is relocked
automatically.
