Downloaded from www.Manualslib.com manuals search engine Immobilizer Control System: 10C-2
• Do not leave ignition key in a place where
temperature is high. High temperature may cause
damage to the transponder built in the ignition key. • Do not turn ignition switch to ON position by bringing
radio antenna close to coil antenna. Or, the
immobilizer control syst em may detect some
abnormal condition and prevent the engine from
starting.
General Description
Immobilizer Control System IntroductionS7RS0BA301001
The immobilizer control system is an anti-theft device that immobilizes the vehicle. It stops the engine from working
and prevents the vehicle from being stolen. It mainly consists of the following components.
• Engine Control Module (ECM)
• Immobilizer control module (ICM) with the built-in coil antenna
• Ignition key with the built-in transponder
A code called the transponder code is memorized in the tran sponder. And, the code is registered with ECM. Basically,
when the ignition switch is turned ON, ECM reads the code by the coil antenna. Then, if the code in transponder in the
ignition key does not match with the one registered with ECM, ECM stops the operati on of the fuel injection so as not
to start up the engine and turns the immobilizer indi cator lamp ON and OFF using CA N communication lines. In the
case of the vehicle equipped with the keyless start system , in addition to the above operation, ECM makes the
immobilizer indicator lamp ON and OFF when it detects a trouble related to ID code verification of the keyless start
system.

Door Lock Function of Keyless Start SystemS7RS0BA501004
When the request switch (1) incorporated in the outside handle of the driver side door, front passenger side door or
rear end door is pushed, the keyless start control modul e (2) activates the center antenna (3) and luggage room
antenna (4) to send out the radio wave in the vehicle compartm ent to check if the remote controller (5) is in the vehicle
compartment or not. When the keyless start control module receives no signal from the remote controller (i.e., the
remote controller does not exist in the vehicle compartment) , it activates the antenna (6) of the door of which the
request switch has been pushed to send the request signal out of the compartment.
If the remote controller exists within the door lock operati on area, it receives the request signal sent from the above
said antenna, sends the ID code of the remote controller and the request signal to the keyless start control module and
at the same time, it makes the operatio n indicator lamp (7) of the remote controller light up. Lighting of the operation
indicator lamp indicates that the remote controller sent the ID code and the request signal.
The keyless start control module compares the ID code sent from the remote controller with the ID code registered in
the keyless start control module. If both ID codes match, the keyless start control module outputs the lock or unlock
request signal (depending on the door lock switch (8) stat e then) to BCM (9). When BCM receives such signal through
CAN communication from the keyless start control module, it activates the door lock actuator to lock or unlock doors.
When the keyless start control module receiv es a signal from the remote controller (i.e., the remote controller exists in
the vehicle compartment), the function of the keyless start system to prevent the remote controller from being closed in
the vehicle works and the keyless start control module sends a request signal to unlock doors to BCM. In this way,
doors are kept unlocked.
Also, when the driver or passenger has left the vehicl e with the remote controller left behind in the vehicle
compartment and locked doors by using the door lock knob or manual door lock switch, the function to prevent the
remote controller from being closed in the vehicle works to unlock doors.
Furthermore, when ID codes of the remote controller and keyless start control module do not match or the remote
controller exists outside of the operation area, doors are not locked or unlocked even if the request switch of the
outside handle is operated.

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
