THEFT DETERRENT / KEYLESS ENTRY  ENTRY AND START SYSTEM(for Entry Function)  Front Passenger Side Door Entry Lock and Unlock Functions do not Operate  


DESCRIPTION

If the entry lock and unlock functions do not operate for the front passenger door only, the request code may not be being transmitted from the front passenger door or the front door outside handle assembly (for Front Passenger Door) (touch sensor). If the entry functions for other doors operate properly, communication between the electrical key transmitter sub-assembly and door control receiver is normal. In this case, there may be a problem with request code transmission (communication between the certification ECU (smart key ECU assembly) and front door outside handle assembly (for Front Passenger Door) (electrical key antenna)), or there may be wave interference.

CAUTION / NOTICE / HINT

NOTICE:
·

When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start. While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

·

The entry and start system (for Entry Function) uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the entry and start system (for Entry Function) after confirming that the communication systems are functioning properly.

·

Before replacing the certification ECU (smart key ECU assembly), refer to Service Bulletin.

·

After repair, confirm that no DTCs are output.

·

Check that there are no electrical key transmitter sub-assemblies in the vehicle.



HINT:
·

If the front passenger side door entry lock and unlock functions do not operate, the cause of the malfunction may be stored in the certification ECU (smart key ECU assembly).

·

If the cause of the malfunction is stored in the certification ECU (smart key ECU assembly), the following table is helpful in checking whether the malfunction was caused by wave interference.

Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly (for Front Passenger Door) and perform an entry function check.

Click hereVehicle Interior>THEFT DETERRENT / KEYLESS ENTRY>ENTRY AND START SYSTEM (for Entry Function)>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 front door outside handle assembly (for Front Passenger Door).

·

When the electrical key transmitter sub-assembly is brought near the front door outside handle assembly (for Front Passenger Door), 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.

·

When checking the operation of the entry lock function several times, it can be operated up to 2 times consecutively. To operate the function 3 times or more consecutively, the doors need to be unlocked once. However, this is only for the entry lock function. Other door lock operations, such as a wireless door lock operation, can be performed consecutively.
