INSPECTION PROCEDURE

NOTICE:

1. 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 (Click here).
   
2. 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(CAN). 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.
   
3. Before replacing the certification ECU (smart key ECU assembly), refer to entry and start system (for Entry Function) (Click here).
   
4. After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".
   
5. The indoor electrical key antenna assemblies have an antenna coil between each terminal.
   
6. The door control receiver assembly is also related to interior verification.
   

1. Using another registered electrical key transmitter sub-assembly, check that the engine starts.

   HINT:

   1. When the electrical key transmitter sub-assembly cannot be verified even though it is inside the detection area, the engine start check can be performed by removing the transmitter battery from the electrical key transmitter sub-assembly and holding the electrical key transmitter sub-assembly near the engine switch.
      
   2. If the engine cannot be started when performing this inspection, the certification ECU (smart key ECU assembly) or steering lock ECU (steering lock actuator assembly) may be malfunctioning.

   Result	Proceed to
   Engine can be started	A
   Engine cannot be started	B

1. Install the transmitter battery to the electrical key transmitter sub-assembly (Click here).
   

2. Bring the electrical key transmitter sub-assembly near the No. 1 indoor electrical key antenna assembly (front floor) and perform an entry and start system check (Click here).
   

   NOTICE:

   Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the No. 1 indoor electrical key antenna assembly (front floor) (Click here).

3. Bring the electrical key transmitter sub-assembly near the No. 2 indoor electrical key antenna assembly (rear floor) and perform an entry and start system check (Click here).
   

   HINT:

   Check that the customize status of the "Ignition Available Area" has been "All" (Click here).

   NOTICE:

   Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the center of the No. 2 indoor electrical key antenna assembly (rear floor) (Click here).

4. Bring the electrical key transmitter sub-assembly near the No. 3 indoor electrical key antenna assembly (inside luggage) and perform an entry and start system check (Click here).
   

   HINT:

   Check that the customize status of the "Ignition Available Area" has been "All" (Click here).

   NOTICE:

   Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the center of the No. 3 indoor electrical key antenna assembly (inside luggage) (Click here).

   HINT:

   1. As the effect of wave interference decreases by moving the electrical key transmitter sub-assembly close to each indoor electrical key antenna assembly, it may be possible to check whether wave interference is the cause of the problem.
      
   2. 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.
      
   3. 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.
      
   4. 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.
      

   OK:

   The engine starts when the electrical key transmitter sub-assembly is held near each indoor electrical key antenna assembly and the engine switch is pressed.
   

1. Check for DTCs (Click here).
   

   OK:

   DTCs are not output.
   

1. Check the following antennas in key diagnostic mode.
   

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

   
   
   

   1. Check the No. 1 indoor electrical key antenna assembly (front floor):

      HINT:

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

   2. Check the No. 2 indoor electrical key antenna assembly (rear floor):

      1. Select either channel 1 or channel 2 and inspect key diagnostic mode for each channel.
         
      2. 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.
         
      3. It is possible to check which indoor electrical key antenna assembly (front floor, rear floor or inside luggage) is operating by the sounding of the buzzer.
         
      4. When the wireless buzzer sounds for all indoor electrical key antenna assemblies, they can be judged as operating properly and a malfunction in the certification ECU (smart key ECU assembly), which performs verification, is suspected.
         
      5. When the wireless buzzer does not sound for all indoor electrical key antenna assemblies, it can be judged that the certification ECU (smart key ECU assembly), which controls the indoor electrical key antenna assemblies, is malfunctioning.
