Audio Unit {Keyless Receiver Circuitl Input Test ('96 - 98 models}
Remove the audio unit, then disconnect the A and B connectors (see page 23-189).
Inspect the connector and socket terminals to be sure they are all making good contact
. lf the terminals are bent, loose or corroded, repair them as necessary, and recheck the system
. lf the terminals look OK, make the following input tests at the connector.
- lf anv test indicates a problem, find and correct the cause, then recheck the system
lf all the inout tests prove OK, the control unit must be faulty; replace it.

Transmitter Test
NOTE:
. lf the doors unlock or lock with the transmitter, but
the LED on the transmitter does not come on, the
LED is faulty; replace the transmitter.
. lf any door is open, you cannot lock or unlock the
door with the transmitter.
. lf you unlocked the doors with thetransmitter, but do
not open any of the doors within 30 seconds, the
doors relock automatically.
. The doors do not lock or unlock with the transmitter
if the ignition key is inserted in the ignition switch.
1. Using a keyless entry checker (07MAJ - SP003001:
. Place the transmitter on the keyless entry check-
er, and press the transmitter button.
- lf the indicator light does not come on, check
for:- a dead or low batterv- Faulty transmitter- lf the ray indicator light comes on, the trans-
mitter is OK.

Storing transmitter codes;
The codes of up to three transmitters can be read into
the keyless receiver unit memory. (lf a fourth code is
stored, the code which was input first will be erased.)
NOTE: lt is important to maintain the time limits
between the steps.
'1. Turn the ignition switch ON (ll).
2. Within 1 to 4 sec., push the transmitter lock or unlock
button with the transmitter aimed at the vehicle.
3. Within I to 4 sec., turn the ignition switch OFF.
4. Within 1 to 4 sec., turn the ignition switch ON 1ll).
5. Within 1 to 4 sec., push the transmitter lock or
unlock button with the transmitter aimed at the
vehicle.
6. Within 1 to 4 sec., turn the ignition switch OFF.
7. Within 4 sec., turn the ignition switch ON (ll).
8. Within 1 to 4 sec., push the transmitter lock or
unlock button with the transmitter aimed at the
vehicle.
9.Within 1 to 4 sec., turn the ignition switch OFF.
Within 4 sec., turn the ignition switch ON (ll).
Within '1 to 4 sec., push the transmitter lock or
unlock button with the transmitter aimed at the
vehicle.
Confirm you can hear the sound of the door lock
acIuarors.
Within 8 sec., aim the transmitters (up to three)
whose codes you want to store at the receiver, and
press the transmitter lock or unlock buttons.
Contirm that you can hear the sound of the door
lock actuators after each transmitter code is stored.

Spring-loaded Lock Connector
Some SRS system connectors have a spring-loaded lock.
Disconnecting
To release the lock, pull the spring-loaded sleeve towardthe stop while holding the opposite half of the connecror.Then pull the connector halves apart.
NOTE: Be sure to pull

Do not pull on thishalf of the connector.
Connecting
1. Hold the pawl-side connector half, and press on theback of the sleeve-side connector half in the directionshown. As the two connector halves are pressed
together, the sleeve is pushed back by the pawl.
NOTE: Do not touch the sleeve.

Switches
These switches move
together; the broken straight
line between them means the,
are mechanically connected.
Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted. all switches are shown
in their normal (rest) position,
with power off.
This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car frame or to a metal
part connected to the frame.
This symbol represents
the bus inside a ground
connector. The dots I

Fuses
This means power is supplied

Current rating
Diodes
A rectifier diode works like a one
way valve. lt allows current to
llow only in the direction of the
arrow.
A Zener diode blocks reverse
current at normal voltages just like
a rectifier diode. At high voltages.
however, a Zener diode allows
current to f low in reverse
oo
Each "T" lerminal (ring type)
is numbered for reference and
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interference) shielding
around a wire. The
shielding is always
connected to ground.
