transmitter, and the door lock signal output (0V) will be sent from the
keyless entry control
unit terminal No. 12 closing the door lock powerrelays 1 and 2 to lock the driver’s and front
passenger’s doors.
While the R.H. and L.H. doors are in the lockedstate, press the UNLOCK switch of the
transmitter once, and the DOOR UNLOCK
switch signal (0 V) will be sent from the keylessentry control unit terminal No. 14 closing the
door lock power relay 2 to unlock the driver’s
door.
Under the above-mentioned conditions, further
press the UNLOCK switch of the transmitter,and the DOOR UNLOCK signal output (0 V)
will be sent from the keyless entry control unitterminal No. 13 closing the door lock power

When the keyless entry system is operated toturn the driver’s door lock switch from the
UNLOCK position to the LOCK position, thelock knob) is locked with the key inserted in
the ignition switch, the ETACS unit grounds the
unlock side circuit of the door lock relay to unlock
all doors. This way, failure to remove the key
is prevented.dome light/foot light blinking signal output
(system voltage) will be sent twice from the
keyless entry control unit terminal No. 11 when
the door lock switch is turned from the LOCK
position to the UNLOCK position, the lighting
signal output (0 V) will be provided for approx.
3 seconds.
NOTE
The dome light winks or comes on when the domelight switch is in the DOOR interlock position.
However, the dome light does not wink while it .is
ON for 6 seconds after closing the door by ETACS
function.Besides the above-mentioned operations, the
keyless entry control unit has the following functions.l
If any door is not opened or closed within 30
seconds from unlocking the door by means ofthe
keyless entry system, the door is
automatically locked.In addition, if the
cryptographic code other than the code storedin the receiver memory is received 30 times
in one minute continuously, operation of the
unit is suspended for 10 minutes.l
Operation is also suspended if the ignition key
remains inserted (key reminder switch: OFF)
and either door is left open (door switch: ON).TROUBLESHOOTING HINTS

PROCEDURE FOR INPUTOFSECURITYCODE FOR RADIOAND TAPE PLAYER WITH ANTI-THEFT SYSTEM
The radio and tape player does not operate in the following
states.
(1) Power supply to the radio and tape player has been sus-
pended for more than one hour continuously by removing
the cable from the battery terminal or disconnecting the
harness connectors.
(2) The power supply to the radio and tape player has been
suspended for more than one hour owing to blown fuse
or discharged battery.(3) The radio and tape player has been replaced.
If the radio and tape player does not operate for these causes,
input the security code by the following procedure to operate
it.
1.Using any of the following methods, confirm the security
code.
(1)
Read the security code indicated on the cards retained
by the user.
(2) If the security code is unknown owing to the user’s
loss of the cards,a. Remove the audio panel and then pull out the
radio and tape player partially.
b.Read the serial No. shown on the name card of
the radio and tape player.
c.Look up the anti-theft code corresponding to the
serial number in the serial number-anti-theft code
table; or, make inquiries to Mitsubishi Motor Sales
of America, Inc.(3) When the radio and tape player is replaced
Read the security code on the cards attached to the
upper surface of the replacement radio and tape player.
NOTE
Deliver the cards (two) to the user.

2.Return power supply for the radio and player to the normal
state.3. Turn the ignition key to the “ACC” position.
4. Press the POWER button, and “code” will be displayed
on the display.
5.Press No.1 through No.4 memory select buttons and setthe
4-digit security code indicated on the card.
Every time each digit key is pressed, the number changes
as follows:
40 +l +2--e 9+0 **-
6.Press the PROG button. After a beep is heard, the radioand tape player will be in the operating state.
7. If the input security code does not agree with that in
memory, “1 Err” is displayed on the display. In a few se-conds, it will change to “code”. So, repeat steps 4 and
5.
NOTE
(1) The security code can be set three times at the most.
(2) The second error is displayed as “2 Err”. If the third
error is made, “3 Err” is displayed and then it changes
to “OFF”.
(3) When setting is attempted four or more times, keeping
the ignition key in the “ACC” or “ON” position for about
one hour will automatically erase the “OFF” display.
