Keyless Engine Start Function
NOTE
Before performing symptom diagnosis procedure for keyless engine start system, check that engine
starts by using ignition key. If it cannot be started by using ignition key, go to “Engine Symptom
Diagnosis in Section 1A”.

Keyless Start System Operation InspectionS7RS0BA504011
Keyless engine start operation
1) Sit in driver seat with re mote controller carried with
you.
2) Check that all doors are closed and ignition key is not inserted in ignition key cylinder.
3) While pushing ignition knob switch (1) of steering lock unit, check if ignition knob switch can be turned
from its lock position.
If key indicator lamp (2) in combination meter lights
in blue and ignition knob switch can be turned from
its lock position in this check, keyless engine start
operation is in good condition.
If key indicator lamp in combination meter lights in
red and ignition knob switch cannot be turned from
its lock position in this check, go to “Keyless Start
System Check”.
NOTE
Pushing ignition knob switch for 5 seconds
or longer causes function to protect steering
lock releasing solenoid against heat to work.
Then steering lock unit stops energizing
solenoid, preventing ignition knob switch
from turning. At the same time, key indicator
lamp in combination mete r turns off. In such
case, take your hand off from ignition knob
switch once and operate it again.

Door Lock Operation (Keyless Start System)S7RS0BA504012
1) Check that all door locks are released and all doors are closed.
2) With remote controller of which ID code is registered in keyless start control m odule carried with yourself,
check that pushing driver door, passenger door or
rear end door request switch once locks all doors.
3) Check that pushing request switch of driver door, passenger door or rear end door once releases all
door locks.
Inspection of Keyless Start Control Module and Its CircuitsS7RS0BA504013
Keyless start control module and its circuits can be che cked at keyless start control module wiring couplers by
measuring voltage and resistance.
CAUTION!
Keyless start control module cannot be checked by itself. It is strictly prohibited to connect voltmeter
or ohmmeter to keyless start control module with coupler disconnected from it.

Voltage Check
1) Disconnect negative (–) cable at battery.
2) Remove keyless start control module from vehicle body referring to “Keyless Start Control Module Removal and
Installation”.
3) Connect connector to keyless start control module.
4) Check voltage at each terminal number of couplers connected.
NOTE
• As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when ignition switch is ON.
• Voltage with asterisk (*) cannot be measured by voltmeter because it is pulse signal.

3) Remove battery (4) from lower case (5).
CAUTION!
Use care not to allow grease or dirt to be
attached on the printed circuit board and the
battery.

4) Replace the battery (lithium disc-type CR 2032 or equivalent battery) so its (+) terminal faces on
remote controller lower case.
5) Install printed circuit board and rubber switch to upper case and then fit lower case securely.
NOTE
• To prevent theft, be sure to break the remote controller be fore discarding it.
• Dispose of the used battery properly according to applicable rules or
regulations. Do not dispose of lithium
batteries with ordinary household trash.

Registration Procedure for Remote Controller
ID Code
S7RS0BA506009
NOTE
• It is possible to register up to 4 remote controllers in keyless start control module.
• Setting keyless start control module to ID code registration mode of remote
controller will erase all remote controller ID
codes that have been registered in keyless
start control module.
Therefore, when re gistering remote
controller ID codes in keyless start control
module, have all of those to be registered
ready and execute their registration at the
same time.
• When registration of more than four remote controller ID codes is attempted,
the oldest remote cont roller ID code will be
erased and that inputted after the fourth
one will be registered.
• When keyless start control module which was used in another vehicle has been
installed, it is nece ssary to perform both
registration of remote controller ID code in
keyless start control module and
registration of ignition key transponder
code in ECM. For registration procedure of
ignition key transponder code, refer to
“Registration of the Ignition Key in Section
10C”.
