ON±VEHICLE INSPECTION
1.CHECK WIRELESS DOOR LOCK CONTROL FUNCTIONS
HINT:

The switch described in this text is a switch for transmitting signals (LO\
CK switch, UNLOCK switch and
luggage door (back door) unlock switch) which is built in the door control t\
ransmitter.

All the functions listed below must be checked in comparison with the re\
mote control operational area.
(a)Put the vehicle under the conditions that allow the wireless control fun\
ction to be operated (See PRE-
CAUTION on page 73±14).
(b) Check the basic function. (1) Check whether the LED of the transmitter lights up 3 times when each switch i\
s pressed 3 times.
HINT:
If the LED does not light up when the switch has been pressed 3 times or more, it may have a dead bat\
tery.
(2) Check that all the doors including the luggage door (back door) lock when t\
he LOCK switch ispressed (However, this will not happen when any door is open).
(3) w/ Double locking system: Check that the double locking system is set when the LOCK switch is pressed within 5 seconds
after the above step (However, the double locking system is not applicable to the luggage door
(back door)).
CAUTION:
Never activate the double locking system when there are people in the vehicle, because all the doors
cannot be opened from inside the vehicle with the system on. If you lock\
the doors by accident, push
UNLOCK switch of the door control transmitter. (4) Check that all the doors including the luggage door (back door) unlock when\
the UNLOCK switchis pressed. Also, check that the double locking system is canceled at th\
e same time.
(5) Check that the luggage door (back door) unlocks when the luggage door (bac\
k door) unlock
switch is pressed.
HINT:
The UNLOCK switch and luggage door (back door) unlock switch can unlock t\
he doors even when any door
is open.
(c) Check the chattering prevention function. (1) Check that the corresponding operation occurs only once, and not repeated continuously whilethe switch is held down. However, when the switch is operated repeatedly at 1 second intervals,
check that the corresponding operation is carried out.
(d) Check the automatic locking function. (1) Check that all the doors including the luggage door (back door) lock automatically as long asnone of them have been opened or locked within approx. 30 seconds after they\
are unlocked
by pressing the switch.
(2) Check that the automatic locking function does not operate when any door incl\
uding the luggage
door (back door) has been opened or all of them have been locked within ap\
prox. 30 seconds
after they are unlocked by pressing the switch.
(e) Check the switch operation fail±safe function. (1) Check that the doors can not be locked by the switch while the key is in the \
ignition key cylinder.
However, this does not apply when the system is in the recognition code registra\
tion mode.
(f) Check the repeat function. (1) Check that all the doors attempt to automatically lock once again 1 second af\
ter the LOCK switchhas been pressed while the movement of the driver side door control knob, which is in the un-
locked state, is being restricted.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major p\
arts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common \
ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.

E GLOSSARY OF TERMS AND SYMBOLS
BATTERY
Stores chemical energy and
converts it into electrical energy.
Provides DC current for the auto’s
various electrical circuits.GROUNDThe point at which wiring attaches to
the Body, thereby providing a return
path for an electrical circuit; without a
ground, current cannot flow.
CAPACITOR (Condenser)A small holding unit for temporary
storage of electrical voltage.HEADLIGHTSCurrent flow causes a headlight
filament to heat up and emit light. A
headlight may have either a single
(1) filament or a double (2) filament
1. SINGLE
FILAMENT
CIGARETTE LIGHTER
An electric resistance heating
element.2. DOUBLE
FILAMENT
CIRCUIT BREAKERBasically a reusable fuse, a circuit
breaker will heat and open if too
much current flows through it.
Some units automatically reset when
cool, others must be manually reset.HORNAn electric device which sounds a
loud audible signal.
DIODEA semiconductor which allows
current flow in only one direction.IGNITION COILConverts low–voltage DC current
into high–voltage ignition current for
firing the spark plugs.
DIODE, ZENER
A diode which allows current flow in one
direction but blocks reverse flow only up
to a specific voltage. Above that potential,
it passes the excess voltage. This acts as
a simple voltage regulator.LIGHTCurrent flow through a filament
causes the filament to heat up and
emit light.
PHOTODIODEThe photodiode is a semiconductor
which controls the current flow
according to the amount of light.LED (LIGHT EMITTING DIODE)
Upon current flow, these diodes emit
light without producing the heat of a
comparable light.
DISTRIBUTOR, IIAChannels high–voltage current from
the ignition coil to the individual
spark plugs.METER, ANALOG
Current flow activates a magnetic
coil which causes a needle to move,
thereby providing a relative display
against a background calibration.
FUSE
A thin metal strip which burns through
when too much current flows through it,
thereby stopping current flow and
protecting a circuit from damage.
FUSIBLE LINK
METER, DIGITALCurrent flow activates one or many
LED’s, LCD’s, or fluorescent
displays, which provide a relative or
digital display.
FUEL
A heavy–gauge wire placed in high
amperage circuits which burns through on
overloads, thereby protecting the circuit.
The numbers indicate the crosssection
surface area of the wires.(for Medium Current Fuse)
(for High Current Fuse or
Fusible Link)MOTOR A power unit which converts
electrical energy into mechanical
energy, especially rotary motion.
