|
Power Source Mode does not Change to ON (IG and ACC) |
DESCRIPTION
When the ignition switch cannot be turned to ACC or ON, interior verification may be abnormal or there may be a malfunction in the ACC relay or IG relay circuit. If interior verification cannot be performed, the certification ECU (smart key ECU assembly) may be malfunctioning or communication may not be possible between the No. 1 indoor electrical key antenna assembly (front floor), No. 2 indoor electrical key antenna assembly (inside luggage compartment)*1 or No. 3 indoor electrical key antenna assembly (inside luggage compartment)*2 and the electrical key transmitter sub-assembly and electrical key and tire pressure monitoring system receiver assembly.
When an electrical key transmitter sub-assembly is brought into the cabin, its key ID code is compared with the key ID code stored in the certification ECU (smart key ECU assembly). If these codes do not match, key verification will fail and the ignition switch will not be able to be turned to ACC or ON.
When a door is unlocked and an electrical key transmitter sub-assembly is brought into the cabin, the certification ECU (smart key ECU assembly) activates the indoor electrical key antenna assemblies to form the interior detection area. The electrical key transmitter sub-assembly then responds to the detection signals with its key ID code. This response signal is received by the electrical key and tire pressure monitoring system receiver assembly and sent to the certification ECU (smart key ECU assembly).

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 Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Start Key(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.
-
The smart key system (for Start Function) uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the smart key system (for Start Function) after confirming that the communication systems are functioning properly.

- Make sure that no DTCs are output. If any DTCs are output, proceed to Diagnostic Trouble Code Chart.
-
If the smart key system (for Start Function) has been disabled, enable the system before performing troubleshooting.

- Inspect the fuses for circuits related to this system before performing the following procedure.
-
Before replacing the certification ECU (smart key ECU assembly) or an electrical key transmitter sub-assembly, refer to Registration.
Click here
- After completing repairs, confirm that the problem does not recur.
- After performing repairs, confirm that no DTCs are output by performing "DTC Output Confirmation Operation."
- The indoor electrical key antenna assemblies have an antenna coil between each terminal.
- The electrical key and tire pressure monitoring system receiver assembly is also related to interior certification.
HINT:
- If interior verification is unsuccessful, Vehicle Control History may be stored.
- If Vehicle Control History has been stored, refer to the Vehicle Control History List to determine the detection conditions and narrow down trouble areas.

CHECK WAVE ENVIRONMENT |
(a) Install the transmitter battery to the electrical key transmitter sub-assembly.
Click here
(b) Bring the electrical key transmitter sub-assembly near the No. 1 indoor electrical key antenna assembly (front floor) and perform a smart key 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).
HINT:
- 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.
- 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.
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 with the brake pedal*1 or clutch pedal*2 depressed.
