Precautions

Precautions in Diagnosing Troubles

S6JB0AA500001

• 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, BCM, TCM (A/T model), 4WD control module (if equipped), ABS or ESP

® control module,

keyless start control module, steering angle sensor (if equipped) 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”.

10E-2 Keyless Start System:

• 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.
– For petrol engine model 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:
For Petrol Engine Model in Section 10C”.

– For petrol engine model 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”.

– For diesel engine model, register the ID code of the keyless start control module in ECM. ID code of the keyless

start control module is registered automatically by registering the password and SECRET KEY CODE to ECM.
For the registration procedure of that, refer to “Procedure after ECM Replacement: For Diesel Engine Model in
Section 10C”.
