DTC No. 51 / No. 52 / No. 53: Driver Side / Passenger Side / Rear End Door Request Switch FailureS7RS0BA504022
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.

Step
Action YesNo
1 Was “Keyless Start System Check” performed? Go to Step 2.Go to “Keyless Start
System Check”.
2 Keyless start control module voltage check
1) Turn ignition switch to OFF position.
2) Disconnect connector from each door request switch.
3) Check for proper connection to all terminals of each door
request switch connector.
4) If OK, measure voltage between “PPL”, “BLU/RED” or “YEL” terminal of related door request switch connector
and vehicle body ground.
Is voltage 10 – 14 V? Go to Step 3.
Go to Step 4.
3 Request switch check
1) Check related door request switch for function referring
to “Front Door (Driver and Passenger Side), Rear End
Door Request Switch Inspection”.
Is each switch in good condition? Substitute a known-
good keyless start
control module and
recheck.
Replace request switch.
4 Wire harness check
1) Turn ignition switch to OFF position.
2) Check for open, short and high resistance in related
circuit.
• Between “PPL” wire terminal of driver side door request switch connector and “G42-16” terminal of
keyless start control module connector
• Between “BLU/RED” wire terminal of passenger side door request switch connector and “G42-36” terminal
of keyless start control module connector
• Between “YEL” wire terminal of rear end door request switch connector and “G42-32” terminal of keyless
start control module connector
Is it in good condition? Substitute a known-
good keyless start
control module and
recheck.
Repair circuit.

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”.

is necessary, register ID code(s) of remote controller.1) Sit in driver seat and close all doors.
2) Check that door lock of driver seat is unlocked.
3) Insert ignition key (1) in to ignition key cylinder.
4) Perform Steps a) through f) described blow within 25 seconds after Step 3).
a) First push manual door lock switch (2) toward
lock side (3) and then push it toward unlock side
(4).
b) Repeat Step a) 2 more times.
c) Push lock side of manual door lock switch.
d) Remove ignition key from ignition key cylinder once and then insert it again.
e) Repeat Step d) 3 more times.
f) Start engine and wait for 3 seconds.NOTE
When 60 seconds elapse after engine is
started, the above process to enter
registration mode will be cancelled.
Therefore, be sure to proceed to the next
step within 60 seconds.

5) Turn ignition switch to OFF position. When ignition switch is turned to OFF position,
buzzer sounds twice and door lock is activated from
lock position to unlock po sition. This operation
indicates that keyless st art control module has
entered registration mode.
6) Push lock or unlock button of remote controller within 30 seconds after Step 5) to be registered.
When lock or unlock button of remote controller is
pushed, buzzer sounds twice, door lock is activated
to lock position and then to unlock position. This
operation indicates that remote controller ID code
has been registered in keyless start control module.
If an additional remote controller needs to be
registered, repeat the procedure of Step 6) within 30
seconds after Step 5).
7) To end registration mode, remove ignition key from ignition key cylinder or turn it to ON position.
If engine start function of keyless start system does
not work after registration , check ECM if DTC P1615
is detected. If it is detected, go to “DTC P1615: ID
Code Does Not Registered (Vehicle equipped with
keyless start system only) in Section 10C”. If it is not
detected, perform registration procedure again.
