When the door lock switch is set to the LOCKside (or UNLOCK side), the LOCK side (or
UNLOCK side) of the door lock relay is turned
ON and the door actuators of all doors operate.l

With the driver’s and front passenger’s doorsunlocked, press the LOCK switch of the
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
relay 1 to lock the front passenger’s door.
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

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the
SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and passenger (from render-
ing the SRS inoperative).
(2) Service or maintenance of any SRS component or
SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3)MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B
TSupplemental Re-
straint System (SRS) and GROUP 00 -Maintenance Service before beginning any service or maintenance of any com-
ponent of the SRS or any
SRS-related component.
NOTE
The SRS includes the following components: impact sensors, SRS diagnosis unit, SRS warning light, air bag module, clock spring
and interconnecting wiring. Other SRS-related components (that may
h,a”” to be removed/installed in connection with SRS serviceor maintenance) are indicated in the table of contents by an asterisk ( ).

TROUBLESHOOTING
LHEADLIGHT
OPERATION

lTurn the lighting switch to “HEAD”, and the con-
tact point of the headlight relay will be closedto turn “ON” the headlight relay.
lWhen the dimmer switch is placed in the LO
position, the headlight low-beams go on. On
vehicles up to 1993 model, when the switch
is placed in the HI position, the headlight high-
beams go on. On vehicles from 1994 model,when the switch is placed in the HI position,
the headlight high-beams and low-beams go
on.
l
When the high-beam is lit or when the passing
switch is activated, the high-beam indicator lightwill be lit.
l
If the driver’s door is opened after the ignition
switch is turned to “OFF” or the ignition switchis turned to “OFF” after the driver’s door is
opened when the headlights are lit, the currentwhich flows to the coil side of the headlight
relay will be cut off by the light automatic shut-OFF unit opening the contact point, and the
headlight relay will be turned “OFF” to automati-
cally shut off the headlights.l
To turn the headlights on again after they are
automatically shut off, turn the lighting switchto “OFF” once and then back to “HEAD”, or
turn the ignition switch to “ACC” or “ON”, and
the
aut0mati.c shut-OFF will be cancelled andthe current will flow from the light automatic
shut-OFF unit to the coil side of the headlightrelay again to close the contact point. Thus,
the headlight relay will be turned “ON” to turnon the headlights.
NOTEWhen the lighting switch is at “HEAD”, the light
automatic shut-OFF system is valid for tail lights,
parking and side marker lights, license plate light,
illumination light, etc.(Refer to
P.54-70.)
(Up to 1993 models)by lighting
l
When the lighting switch is placed in the HEAD
position, current flows through multi-purpose
fuse (6) to the lighting switch, and the ETACScontrol unit. Then the UP timer circuit in the
LETACS control unit is operated, and currentflows from the ETACS control unit to the U con-tact of the pop-up motor U/D (UP/DOWN)
switch, the coil of the pop-up motor relay and
ground, causing the contacts of the pop-up mo-
tor relay to close.
When the contacts of the pop-up motor relay
close, current flows through the contacts of the
pop-up motor relay to the pop-up motor and
ground, causing the pop-up motor to rotate,
which brings the headlights to the UP position.
The pop-up motor rotates until the automatic
UP stop position is reached, then the contactsof the interlocked U/D (UP/DOWN) switch
change from the U to D contacts. As a result,
the contacts of the pop-up motor relay opento cut off the current supplied to the pop-up
motor. Then the pop-up motor ceases to rotate,
holding the headlights in the UP position.l
When the lighting switch is placed in the TAIL
or OFF position, current flows through the multi-
purpose fuse (6) to the lighting switch, and the
ETACS control unit. Then the DOWN timer cir-
cuit in the ETACS control unit is operated and
current flows from the ETACS control unit to
the DOWN contacts of the pop-up motor U/D
(UP/DOWN) switch, the coil of the pop-up motor
relay and ground, causing the contacts of the
pop-up motor relay to close.
When the contacts of the pop-up motor relay
close, current flows through the contacts of the
pop-up motor relay to the pop-up motor andground, causing the pop-up motor to rotate,
which brings the headlights to the DOWN posi-
tion.
The pop-up motor rotates until the automatic
DOWN stop position is reached, then the con-
tacts of the interlocked U/D (UP/DOWN) switch
change from the D to U contacts. As a result,
the contacts of the pop-up motor relay open
to cut off current supply to the pop-up motor.
Then the pop-up motor ceases to rotate, holding
the headlights in the DOWN position.
switch> (Up to 1993 models)by POPUPl
When the pop-up switch is placed in the UP
position, current flows through multi-purpose
fuse (6) to the lighting switch, the pop-up switch
and the ETACS control unit, which brings the
headlights to the UP position and holds them
in the UP position just like when they are oper-
ated by the lighting switch.l
When the pop-up switch is placed in the DOWN
position, current flows through the multi-purpose
fuse (6) to the lighting switch, the pop-up switch
and the ETACS control unit, which brings the
headlights to the DOWN position and holds them
in the DOWN position just like when they are
operated by the lighting switch.
