Keyless Start System Operation InspectionS6RW0DA504011
Keyless Engine Start Operation
1) Sit in driver seat with remote 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 light (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 light 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
light in combination meter turns off. In such
case, take your hand off from ignition knob
switch once and operate it again.
Door Lock Operation (Keyless Start System)S6RW0DA504012
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 module carried with yourself,
check that pushing driver door request switch once
locks all doors.
3) Check that pushing request switch of driver door,
passenger door or rear end door once releases
corresponding door lock.
4) Check that pushing again request switch pushed in
Step 3) releases all door locks.
NOTE
If door of which request switch has been
pushed is opened/closed before performing
Step 4), all door locks will not be released
even when Step 4) is performed. If Step 4) is
performed after door is opened/closed, only
the door of which request switch was pushed
will be locked.
Inspection of Keyless Start Control Module and
Its Circuits
S6RW0DA504013
Keyless start control module and its circuits can be
checked 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.

No DTC Detection After Performing DTC CheckS6RW0DA504014
Wiring Diagram
Description
The keyless start control module detects DTC by using signals from the key reminder and driver side door request
switches. The keyless start control module makes the key indicator light in the combination meter flash on and off by
using CAN communication.
