Keyless Engine Start FunctionS7RS0BA501003
When the ignition knob switch (2) installed to the steering lock unit (1) is pushed, the keyless start control module (3)
activates the center antenna (4) to send out the request signa l in the vehicle compartment. When the remote controller
(5) receives the request signal from th e center antenna, it transmits the ID code to the keyless start control module.
The keyless start control module compares the ID code sent by the remote controller with the ID code registered in the
keyless start control module. When these ID codes match, the keyless start control module makes the key indicator
lamp (7) in the combination meter (6) light in blue and unlocks the steering lock unit to enable the ignition knob switch
to turn. When the ignition knob switch is turned to ON posit ion in this state, ID codes of ECM and keyless start control
module are compared through CA N communication (immobilizer function). Wh en they match, turning the ignition knob
switch to start position will start the engine.
NOTE
When ignition knob switch is at ACC or ON position (engine not running) and any door has been kept
open for a certain time, it may happen that engine fails to start. In such a case, turn ignition knob
switch to OFF position once and then try to start engine again.

When the ID code from the remote controller and the ID code registered in the keyless start control module do not
match or when the remote controller is outside the operation area of the remote controller and the ignition knob switch
is pushed, the steering lock unit cannot be unlocked and so the ignition knob switch cannot be turned. Then, the
keyless start control module makes the key indicator lamp in t he combination meter light in red to warn the driver that
it is not possible to turn the ignition knob switch. Also, when the ID code of ECM and that of the keyless start control
module do not match, the engine cannot be started even if the ignition knob switch is turned to the start position. Then
ECM makes the immobilizer light in the combination mete r flash to warn the driver that it is not possible to start the
engine.

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”.
