DESCRIPTION
When the wireless operation can be used to lock and unlock the doors, communication between the electrical key and TPMS receiver assembly and certification ECU (smart key ECU assembly) is normal. If the entry lock and unlock functions do not operate, the entry cancel function may be set through the customize function, there may be communication problems between the electrical key transmitter sub-assembly and vehicle, or there may be wave interference.

CHECK WAVE ENVIRONMENT |
(a) Move the electrical key transmitter sub-assembly as described below and perform the operation inspection.
HINT:
(1) Bring the electrical key transmitter sub-assembly approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the front door outside handle assembly LH and perform a driver door entry lock and unlock operation check. HINT: Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the door handle. |
|
(2) Bring the electrical key transmitter sub-assembly approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the front door outside handle assembly RH and perform a front passenger door entry lock and unlock operation check. HINT: Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the door handle. |
|
(3) Bring the electrical key transmitter sub-assembly approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the electrical key antenna (outside luggage compartment) and perform an entry back door open function check. HINT: Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the rear bumper. |
