Replacement of Transmitter Battery S7RS0B9606014
If transmitter becomes unreliable, replace transmitter
battery as follows.
1) Remove screw (1) and transmitter cover (2).
2) Remove transmitter (3) from transmitter holder (4).
CAUTION!
Use care not to allow grease or dirt to be
attached on the printed circuit board and the
battery.

3) With tip of flat blade screwdriver put in slot of transmitter, pry it open.
4) Replace the battery (lithium disc-type CR 1620 or equivalent battery) so its (+) terminal faces “+” mark
on transmitter.
5) Fit together transmitter (3) and install it into
transmitter holder (4).
6) Install transmitter co ver (2) and screw (1).

Programming Transmitter Code for Keyless
Entry System (Vehicle without Keyless Start
System)
S7RS0B9606015
NOTE
• Three transmitter codes can be registered.
• When a new transmitter code is registered, the oldest one will be cleared.
• As for vehicle equipped with keyless start system, perform “Registration Procedure
for Remote Controller ID Code in Section
10E” instead of “Programming Transmitter
Code for Keyless Entry System (Vehicle
without Keyless Start System):”.

If transmitter or BCM (included in junction block
assembly) is replaced with a new one or additional
transmitter(s) is necessary, program transmitter code(s).
1) Confirm that all doors are closed and ignition key is
out of ignition key cylinder.
2) Open driver side door.

6Combination meter operation check
1) Connect connectors of disconnected control modules
communicating by means of CAN.
2) Turn ignition switch to ON position.
3) Check combination meter operation for seat belt reminder light (fastening and unfastening driver side
seat belt).
Are they OK? Go to Step 7.
Check combination
meter power and
ground circuit. If circuit
is OK, substitute a
known-good
combination meter and
recheck.
7 Key indicator light operation check
1) Turn ignition switch to OFF position.
2) Push ignition knob switch of steering lock unit.
Does key indicator light turn ON? Go to Step 8.
Check keyless start
control module power
and ground circuit. If
circuit is OK, substitute
a known-good keyless
start control module and
recheck.
8 DTC check of BCM
1) Disconnect connector of any one of control module other
than BCM.
2) Recheck BCM for DTC.
Is DTC U1144 (No.1144) detected? Disconnect connectors
of control modules other
than the one whose
connector is
disconnected in Step 1)
one by one and check
that DTC U1144 is
detected by BCM each
time connector is
disconnected. When
DTC U1144 is not
detected by BCM while
checking in this way, go
to description under
“NO” below. If DTC
U1144 is detected by
BCM even when
connectors of all control
modules that use CAN
communication with
BCM are disconnected,
substitute a known-
good BCM and recheck.Check power and
ground circuit of control
module disconnected in
Step 1). If circuit is OK,
substitute a known-
good control module
disconnected in Step 1)
and recheck.
