Step Action YesNo
1 Fuse check
1) Turn ignition switch to OFF position.
2) Check circuit fuse and main fuse for condition.
Are fuses in good condition? Go to Step 2.
Replace fuse(s) and
check for short.
2 Power supply circuit check
1) Disconnect connector from keyless start control module.
2) Check for proper connection to “G42-10”, “G42-11” and
“G42-15” terminals of keyless start control module
connector.
3) If OK, measure voltage between the following terminals. • When ignition switch is at OFF positionBetween “G42-10” terminal of keyless start control
module connector and vehicle body ground: 10 – 14 V
• When ignition switch is at ACC position Between “G42-11” terminal of keyless start control
module connector and vehicle body ground: 10 – 14 V
• When ignition switch is at ON position Between “G42-15” terminal of keyless start control
module connector and vehicle body ground: 10 – 14 V
Is check result satisfactory? Go to Step 3.
Repair power supply
circuit.
3 Ground circuit check
1) Check for proper connection to “G42-9” terminal of
keyless start control module connector.
2) If OK, measure resistance between “G42-9” terminal of keyless start control module connector and vehicle body
ground.
Is resistance 1
Ω or less? Power and ground
circuit is in good
condition.
Repair ground circuit.

Wiring Diagram3
CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of all control modules
communicating by means of CAN.
3) Check CAN communication circuit between control modules for open, short and high resistance.
Is each CAN communication circuit in good condition? Go to Step 4. Repair circuit.
4 DTC check of keyless start control module
1) Turn ignition switch to OFF position.
2) Connect connectors of disconnected control modules
communicating by means of CAN.
3) Disconnect connector of any one control module other than keyless start control module.
4) Recheck keyless start control module for DTC.
Is DTC No.33 detected? Using same method,
disconnect connectors
of control module other
than keyless start
control module one by
one to check if DTC
No.33 is detected.
If DTC No.33 is
detected even through
connector of control
module other than
keyless start control
module is disconnected,
substitute a known-
good keyless start
control module and
recheck.Check power and
ground circuit of
disconnect control
module. If circuit is OK,
substitute a known-
good disconnected
control module and
recheck.

Removal1) Disconnect negative (–) cable at battery.
2) Remove glove box from instrument panel.
3) Remove keyless start cont rol module (1) as follows.
• For vehicle equipped with M/T:
a. Disconnect connector from keyless start control module.
b. Remove keyless start control module mounting bolt and then remove keyless start
control module from steering support member
(2).
• For vehicle equipped with A/T: a. Remove TCM (3) from vehicle body referring to “Transmission Control Module (TCM)
Removal and Installation in Section 5A”.
b. Disconnect connector from keyless start control module.
c. Remove keyless start control module mounting bolt and then remove keyless start
control module from steering support member.
Installation
For installation, reverse removal procedure.
If Keyless start control module is replaced, register ID
code of remote controller in to Keyless start control
module, referring to “Registration Procedure for Remote
Controller ID Code”.
Remote Controller InspectionS7RS0BA506007
Check that remote controller operation indicator lamp (3)
lights up when lock (1) or un lock (2) button of remote
controller is pushed.
If it doesn’t light up in this check, replace battery and
then recheck. If it doesn’t light up even after battery
replacement, replace remote controller.
NOTE
When remote controller transmits lock or
unlock signal, it makes operation indicator
lamp light up.

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”.
