Diagnostic Information and Procedures
Precautions in Diagnosing TroublesS6RW0DA504001
• The keyless start system executes data transmission/
reception by means of the 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
light.
• 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” before inspection and observe
what is written there.
• Communication of ECM, TCM (A/T model), BCM,
ABS control module, 4WD control module (if
equipped), keyless start control module and
combination meter is established 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 register remote controller ID
code to keyless start control 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 being
serviced, register the ID code of the remote controller
to the keyless start control module first and then the
following code.
– With immobilizer control system, register the
ignition key transponder code for the immobilizer
control system in ECM. For registration procedure
of that, refer to “Registration of the Ignition Key in
Section 10C”.
– Without immobilizer control system, register the
steering lock unit ID code in keyless start control
module. For registration procedure of that, refer to
“Keyless Start Registration”.
Self-Diagnosis FunctionS6RW0DA504002
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 area 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 light in the combination meter
flashing in a specific pattern. For DTC indication, refer to
“DTC Check” and for the clearing procedure, to “DTC
Clearance”.
