DTC check of keyless start control module
1) Turn ignition switch to OFF position.
2) Disconnect connector of any one of control module other
than keyless start control module.
3) Recheck keyless start control module for DTC.
Is DTC No.31 detected? Using same method,

of control module other
than keyless start
control module one by
one to check if DTC
No.31 is detected.
If DTC No.31 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
disconnected control
module and recheck. If
circuit is OK, substitute
a known-good
disconnected control
module and recheck.

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.

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”.
