THEFT DETERRENT / KEYLESS ENTRY SMART ENTRY AND START SYSTEM(for Entry Function) Luggage Compartment Door Entry Unlock Function does not Operate when Key is Outside Luggage Compartment

DESCRIPTION

If the entry luggage compartment door open function does not operate, there may be a malfunction in the luggage electrical key switch circuit or certification ECU (smart key ECU assembly), which receives a signal from the luggage electrical key switch circuit, or a communication error between the vehicle (electrical key antenna (outside luggage compartment)) and electrical key transmitter sub-assembly.

4.CHECK WAVE ENVIRONMENT

1.865,1.427 2.177,1.625 0.313,0.198 10 false *a

*a	Approximately 0.3 m (0.984 ft.)

Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the electrical key antenna (outside luggage compartment) and perform an entry luggage compartment open function check.

HINT:: ·

Communication may not be possible if the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the rear bumper.

·

When the electrical key transmitter sub-assembly is brought near the electrical key antenna (outside luggage compartment), the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.

·

If the inspection result is that the problem only occurs in certain locations or at certain times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

·

There may be wave interference if the vehicle is near broadcasting antennas, large video displays, wireless garage door opener systems, wireless security cameras, home security systems, etc. In this case, move the vehicle to a different location and check if there is any improvement.

·

If a tool for checking radio waves, such as a signal strength meter, is available, move around the area while observing both the LF band (used by the vehicle antenna to form the detection area) and RF band (used by the electrical key transmitter sub-assembly for transmission) to check for locations where there is wave interference.

Result:

Proceed to
OK
NG

OK:: Entry function operates normally.

*a	0.7 to 1 m (2.30 to 3.28 ft.)

Select either channel 1 or channel 2 and inspect using key diagnostic mode for each channel.

When the electrical key transmitter sub-assembly is held at the same height as the rear bumper upper surface, align it with the center of the rear of the vehicle and check that the wireless door lock buzzer sounds.

HINT:: ·

Hold the electrical key transmitter sub-assembly at the same height as the rear bumper upper surface and align it with the center of the rear of the vehicle (0.7 to 1 m (2.30 to 3.28 ft.)). Make sure that the direction of the electrical key transmitter sub-assembly is as shown in the illustration.

·

If the buzzer sounds, it can be determined that the luggage compartment exterior transmitter is operating normally.

·

If the buzzer sounds with [CH1] displayed but not with [CH2], the electrical key transmitter sub-assembly cannot be detected by channel 2 due to a malfunction, such as wave interference.

OK:: Wireless door lock buzzer sounds.
