5. Indicator lamp

INPUT SIGNAL PROCEDURES
SIMPLIFIED WIRING SYSTEM (SWS)54B-473
DIAGNOSTIC PROCEDURE
Step 1. Pulse check
Check whether the ETACS-ECU receives signal from a trans-
mitter or not. For this check, you should use the 4-button-type
transmitter (integrated with a key), which has already been reg-
istered.
NOTE: For how to register the keyless entry transmitter
encrypted code, refer to GROUP 42
On-vehicle Service
P.42-73.
OK: The MUT-III sounds or the voltmeter needle fluctu-
ates.
Q: Is the check result normal?
YES : Go to Step 2.
NO : Go to Step 4.
Step 2. Check the transmitter battery.
Refer to GROUP 42
Keyless entry system P.42-70.
Q: Is the check result normal?
YES : Go to Step 3.
NO : Replace the keyless entry key integrated transmitter
battery.
Step 3. Register the encrypted code, and then retest the
system.
(1) Register the keyless entry transmitter again.
(2) Check that each signal is received from the keyless entry
transmitter.
Q: Is the check result normal?
YES : The trouble can be an intermittent malfunction (Refer
to GROUP 00
How to Cope with Intermittent
Malfunction P.00-14).
NO : Replace the keyless entry transmitter.
Step 4. Retest the system.
Check that each signal is received from the keyless entry key
integrated transmitter.
Q: Is the check result normal?
YES : The trouble can be an intermittent malfunction (Refer
to GROUP 00
How to Cope with Intermittent
Malfunction P.00-14).
NO : Replace the ETACS-ECU. System switch Check condition

KEYLESS ENTRY SYSTEM
GENERAL DESCRIPTIONBGBJABIE
Antenna and receiver are incorporated in the
ETACS-ECU.
ID code can be registered by using Diagnostic
tool (MUT-III).
Transmitter is a key holder type, which incorpo-
rates lock button, unlock button, trunk button and
panic button .
When the transmitter unlock button is pressed
once, the driver's door will be unlocked. If the but-
ton is pressed twice, all the doors will be
unlocked. The adjustment function also allows
you to open all the doors by pressing the unlock
button only once. For further details on using the
multi-center display to adjust the unlock opera-
tion, refer to GROUP 54B, On-vehicle Service
P.54B-486.
When the transmitter is operated, the answer-
back function will work as follows:
The answerback operation can be altered as fol-
lows:NOTE: Enabling/disabling the hazard warning
light flashing, the horn sounding in accordance
with the answerback function. For further details
on using the transmitter to adjust answerback,
P.42-72 see the section below. For further details
on using the multi-center display to adjust
answerback, refer to GROUP 54B, On-vehicle
Service P.54B-486. ITEM OPERATION

KEYLESS ENTRY SYSTEM
BODY42-68
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.
KEYLESS ENTRY SYSTEM DIAGNOSISBGBCJGAI
The keyless entry system is controlled by the Simpli-
fied Wiring System (SWS). Refer to GROUP 54B,
