Inspection of BCM and its CircuitsS7RS0BA204018
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 Check1) Disconnect negative (–) cable at battery.
2) Remove BCM (included in junction block assembly) refe rring to “BCM (Included in Junction Block Assembly)
Removal and Installation”.
3) Connect connectors to BCM (1) and junction block assembly (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 Assembly”.
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.

Keyless Engine Start Function
NOTE
Before performing symptom diagnosis procedure for keyless engine start system, check that engine
starts by using ignition key. If it cannot be started by using ignition key, go to “Engine Symptom
Diagnosis in Section 1A”.

Keyless Start System Operation InspectionS7RS0BA504011
Keyless engine start operation
1) Sit in driver seat with re mote controller carried with
you.
2) Check that all doors are closed and ignition key is not inserted in ignition key cylinder.
3) While pushing ignition knob switch (1) of steering lock unit, check if ignition knob switch can be turned
from its lock position.
If key indicator lamp (2) in combination meter lights
in blue and ignition knob switch can be turned from
its lock position in this check, keyless engine start
operation is in good condition.
If key indicator lamp in combination meter lights in
red and ignition knob switch cannot be turned from
its lock position in this check, go to “Keyless Start
System Check”.
NOTE
Pushing ignition knob switch for 5 seconds
or longer causes function to protect steering
lock releasing solenoid against heat to work.
Then steering lock unit stops energizing
solenoid, preventing ignition knob switch
from turning. At the same time, key indicator
lamp in combination mete r turns off. In such
case, take your hand off from ignition knob
switch once and operate it again.

Condition Possible cause Correction / Reference Item
Engine can not be started
by turning Ignition knob

Replace fuse(s) and check for short circuit.
Remote controller battery dead Replace battery.
Remote controller faulty Check remote controller for operation referring
to “Remote Controller Inspection”.
Steering lock unit faulty Check steering lock unit for operation referring
to “Steering Lock Unit Inspection”.
Wiring or grounding faulty Repair circuit.
Antennas or keyless start control
module faulty Check input and output signals of keyless start

1) Check that all door locks are released and all doors are closed.
2) With remote controller of which ID code is registered in keyless start control m odule carried with yourself,
check that pushing driver door, passenger door or
rear end door request switch once locks all doors.
3) Check that pushing request switch of driver door, passenger door or rear end door once releases all
door locks.
Inspection of Keyless Start Control Module and Its CircuitsS7RS0BA504013
Keyless start control module and its circuits can be che cked at keyless start control module wiring couplers by
measuring voltage and resistance.
CAUTION!
Keyless start control module cannot be checked by itself. It is strictly prohibited to connect voltmeter
or ohmmeter to keyless start control module with coupler disconnected from it.

Voltage Check
1) Disconnect negative (–) cable at battery.
2) Remove keyless start control module from vehicle body referring to “Keyless Start Control Module Removal and
Installation”.
3) Connect connector to keyless start control module.
4) Check voltage at each terminal number of couplers connected.
