Exit conditions from the adjustment mode
The ETACS-ECU cancels the adjustment mode when any of the following conditions is satisfied:
•
Diagnosis control: OFF (Disconnect the MUT-II>)
•
Key reminder switch: ON (Pull out the ignition key.)
•
Ignition switch: Other than LOCK (OFF)
•
Door switch: ON (Open the door)
•
After the ETACS_ECU has entered the adjustment mode, no adjustment is made within 3 minutes (If
any adjustment is made within 3 minutes, the ETACS-ECU monitors an adjustment operation for
other 3 minutes.
•
Other warning buzzer(s) sounds
3.
Adjustment of functions
Function Adjustment procedure
Keyless entry answerback function When the transmitter lock switch is turned on twice continuously
within 2 seconds, the lock answerback function toggles on and off.
•
If the function toggles on, the buzzer sounds once (default con-
dition).
•
If the function toggles off, the buzzer sounds twice,
When the transmitter unlock switch is turned on twice continuously
within 2 seconds, the unlock answerback function toggles on and
off.
•
If the function toggles on, the buzzer sounds once (default con-
dition).
•
If the function toggles off, the buzzer sounds twice,
Initialisation of all the ETACS func-
tions (From deactivation to activa-
tion)When the tailgate switch remains on for more than 20 seconds, th
buzzer sounds twice and he answer-back function of the keyless
entry system is initialised.
The buzzer will sound in 10 seconds (indicating that the ETACS-
ECU enters the adjustment mode), but the washer switch must re-
mains off for 20 seconds in order to initialise all the functions.
If the tailgate switch remains on for more than 20 seconds without
entering the adjustment mode, the system enters the adjustment
mode in 10 seconds, but does not initialise all of the functions.
