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
switch Circuit fuse(s) blown
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
control module referring to “Inspection of
Keyless Start Control Mo
dule and Its Circuits”.
ECM faulty Check input and output signal of ECM referring
to “Inspection of ECM and Its Circuits in
Section 1A”.

DTC No. 13 / No. 14: Release Signal Error from Steering Lock Unit / Steering Lock Unit MalfunctionS7RS0BA504018
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure1) Clear DTC referring to “DTC Clearance”.
2) Turn ignition knob switch pushing ignition knob switch.
3) Check DTC referring to “DTC Check”.
Troubleshooting
Replace steering lock unit and recheck.
NOTE
DTC No. 13 is also set is such case where the keyless start control module which was used in another
vehicle is installed, the remote controller ID code is registered in it but the ignition key transponder
code is not registered in ECM. Therefore, when DTC No. 13 is detected, register the ignition key
transponder code in ECM before replacing the steering lock unit.

DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Clear DTC referring to “DTC Clearance”.
2) Turn ignition knob switch pushing ignition knob switch.
3) Push request switch of each door.
4) Check DTC referring to “DTC Check”.
Troubleshooting
Substitute a known-good keyless start control module and recheck. 3
Steering lock unit power supply voltage check
1) Connect connector to keyl ess start control module.
2) Measure voltage between “G22-3” terminal of steering lock unit connector and vehicle body ground.
Is voltage 4 – 6 V? Replace steering lock
unit.
Substitute a known-
good keyless start
control module and
recheck.
