Precautions
Precautions in Diagnosing Troubles for Combination MeterS7RS0B9300001
Combination meter uses signals (information) from each control module by CAN communication to control
speedometer, tachometer, engine coolant temp meter, warning light and indicator light (other than air bag warning
light, high beam indicator light, EPS warn ing light and turn signal indicator light). Therefore, check that no DTC is
detected in each module before performing combination me ter symptom diagnosis. If any DTC is detected, correct
trouble indicated by that DTC troubleshooting first.

Operation Area of Remote ControllerS7RS0BA501005
Shown below are the operation areas of the remote controller for the keyless engine start function and door lock
function of the keyless start system.
However, even when the remote controller is within the operation area as shown above, there are cases where the
keyless start system doesn’t work under certain conditi ons as described below. And when the keyless engine start
function doesn’t work, the key indicator la mp in the combination meter may light up.
• Doors cannot be locked or unlocked using the doo r lock function of keyless start system when:
– The remote controller which has been registered in the keyless start control module and another un-registered one are both carried at the same time
– The remote controller is kept in some metallic co ntainer which disturb radio wave transmission/reception
– One of doors is open
– The ignition key is inserted in the ignition key cylinder
• The function of the keyless start system to prevent the remote controller from being closed in the vehicle
compartment doesn’t work when:
– The remote controller is in the door pocket or in the glove box
– The remote controller is kept in some metallic co ntainer which disturb radio wave transmission/reception
– The remote controller is placed close to outside of the vehicle compartment (such as on the instrument panel beside the front window shield glass or in a corner of the luggage room)
• The ignition knob switch cannot be turned usin g the keyless engine start function fails to turn:
– The remote controller which has been registered in the keyless start control module and another un-registered one are both carried at the same time
– The remote controller is kept in some metallic cont ainer which disturbs radio wave transmission/reception
– The ignition knob switch has been pushed for 5 seconds or longer
– The remote controller is placed close to outside of the vehicle compartment (such as on the instrument panel beside the front window shield glass or in a corner of the luggage room)

Diagnostic Information and Procedures
Precautions in Diagnosing TroublesS7RS0BA504001
• The keyless start system executes data transmission/reception by means of th e radio wave. Therefore,
proper operation may not be obtained if use of the
door lock function and engine start function of the
keyless start system is attempted near the place
where strong radio wave is emitted (TV and radio
broadcasting stations, etc.).
• Diagnostic information stored in keyless start control
module memory can be checked only by key indicator
lamp.
• Be sure to use the trouble diagnosis procedure as described in “Keyless Start System Check”. Failure to
follow it may result in incorrect diagnosis. (Some other
DTC may be stored by mistake in the memory of
keyless start control module during inspection.)
• Be sure to read “Precautions for Electrical Circuit Service in Section 00” befo re inspection and observe
what is written there.
• Communication of ECM, BCM, TCM (A/T model), ABS control module, keyless start control module and
combination meter is estab lished by CAN (Controller
Area Network). (For detail of CAN communication for
keyless start control module, refer to “CAN
Communication System Description”). Therefore,
handle CAN communication line with care referring to
“Precaution for CAN Communication System in
Section 00”. • Replacement of the keyless start control module
When keyless start control module is replaced with
new one, make sure that r egister remote controller ID
code to keyless start co ntrol module correctly
according to “Registration Procedure for Remote
Controller ID Code”.
• Keyless start control module substitution When the keyless start control module used in
another vehicle was installed in the vehicle, register
the ID code of the remote controller in the keyless
start control module as well as the ignition key
transponder code fo r the immobilizer control system in
ECM. For the registration procedure of the ignition key
transponder code, refer to “Registration of the Ignition
Key in Section 10C”.
Self-Diagnosis FunctionS7RS0BA504002
The keyless start control module has self-diagnosis
function to monitor the system components and circuits
while the keyless start system is at work. When the
keyless start control module detects an abnormality in
the system, it saves the ar ea where such abnormality
has occurred as a DTC in its memory. The DTC stored in
memory of the keyless start control module is indicated
by the key indicator lamp in the combination meter
flashing in a specific pattern. For DTC indication, refer to
“DTC Check” and for the clearing procedure, to “DTC
Clearance”.
Keyless Start System Diagnosis IntroductionS7RS0BA504003
To ensure that the trouble diagnosis is done accurately
and smoothly, observe “Precautions in Diagnosing
Troubles” and follow “Keyless Start System Check”.
Keyless Start System CheckS7RS0BA504004
Step Action YesNo
1 1) Record details of the problem. For your record, use of a questionnaire form will facilit ate collecting information for
proper analysis and diagnosis.
2) Check if the problem described in “Customer Questionnaire (Example)” actually occurs in the vehicle.
(This step should be performed with the customer if
possible.)
Perform “Keyless Start System Operation Inspection”
procedure to check if the symptom which has occurred is
abnormal or not.
3) Check for DTC referring to “DTC Check”, and then record DTC(s).
4) Clear DTC referring to “DTC Clearance” if any DTC exists, and then recheck for DTC.
Is any DTC still detected? Go to Step 2.
Go to Step 3.
2 1) Check and repair referring to applicable “DTC Table”. Are check and repair complete? Go to Step 5.
Check and repair
malfunction part(s), and
go to Step 5.

Controller ID Code”.
Remote Controller InspectionS7RS0BA506007
Check that remote controller operation indicator lamp (3)
lights up when lock (1) or un lock (2) button of remote
controller is pushed.
If it doesn’t light up in this check, replace battery and
then recheck. If it doesn’t light up even after battery
replacement, replace remote controller.
NOTE
When remote controller transmits lock or
unlock signal, it makes operation indicator
lamp light up.

Replacement of Remote Controller BatteryS7RS0BA506008
If remote controller operation i ndicator lamp fails to light
up when lock or unlock button of remote controller is
pushed, replace its battery as follows.
1) If ignition key (1) is inse rted in remote controller,
remove it.
2) With tip of flat blade screwdriver (2) put in slot (3) of remote controller (4), pry it open.1
