CAUTION / NOTICE / HINT

NOTICE:
·

When using the GTS with the ignition 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 the vehicle type 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 smart 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 smart 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) or main body ECU (multiplex network body ECU), refer to Service Bulletin.

·

After repair, confirm that no DTCs are output.

·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

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

·

Before performing the inspection, check that DTC B124296 (wireless door lock control) is not output.

a.

Bring the electrical key transmitter sub-assembly near the door control receiver and perform a wireless operation 2 or more times*.

*: When the wireless function is operated, channel 1 and 2 are used alternately. If the first wireless operation is performed successfully and the second wireless operation fails, wave interference may be occurring for either channel.


HINT:
·

When the electrical key transmitter sub-assembly is brought near the door control receiver, 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.

25.CHECK WAVE ENVIRONMENT
a.

Bring the electrical key transmitter sub-assembly near the door control receiver and perform a wireless operation 2 or more times*.

*: When the wireless function is operated, channel 1 and 2 are used alternately. If the first wireless operation is performed successfully and the second wireless operation fails, wave interference may be occurring for either channel.


HINT:
·

When the electrical key transmitter sub-assembly is brought near the door control receiver, 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.
