Precautions In Diagnosing Troubles
WARNING: This page is about a different variant/trim than selected.
- 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 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 PRECAUTION FOR CAN COMMUNICATION SYSTEM before inspection and observe what is written there.
- Communication of ECM, BCM, TCM (A/T model), 4WD control module (if equipped), ABS control module (vehicle not equipped with ESP®), ESP® control module (vehicle equipped with ESP®), 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 OF KEYLESS START SYSTEM ). Therefore, handle CAN communication line with care referring to PRECAUTIONS FOR INSTALLING MOBILE COMMUNICATION EQUIPMENT .
- 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 (vehicle equipped with immobilizer control system) 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 for the immobilizer control system in ECM. For the registration procedure of the ignition key transponder code, refer to REGISTRATION OF THE IGNITION KEY .
