Replacement of Transmitter Battery (Other than
Keyless Start Model)
S6RW0D9606014
NOTE
For keyless start model, perform
“Replacement of Remote Controller Battery
in Section 10E” instead of “Replacement of
Transmitter Battery (Other than Keyless Start
Model)”.

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 cover (2) and screw (1).7) Make sure that door locks can be operated with
transmitter.
NOTE
• To prevent theft, be sure to break the

Inspection of BCM and Its CircuitsS6RW0DA204017
BCM and its circuits can be checked at BCM wiring couplers by measuring voltage and resistance.
CAUTION!
BCM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to BCM
with couplers disconnected from it.

Voltage Check
1) Disconnect negative cable (–) at battery.
2) Remove BCM (included in junction block) referring to “BCM (Included in Junction Block) Removal and Installation”.
3) Connect connectors to BCM (1) and junction block (2).
4) Check voltage at each terminal number of couplers connected.
For connector and terminal number, refer to “Connector Layout Diagram of BCM and Junction Block”.
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 (*) can not be measured by voltmeter because it is pulse signal.
Check it with oscilloscope if necessary.
