CHECK WAVE ENVIRONMENT
| *1 | Approximately 0.3 m |
| *2 | Vehicle Center |
Bring the electrical key transmitter approximately 0.3 m (0.984 ft.) from the outside electrical key oscillator (in rear bumper) and perform an entry luggage compartment open function check.
Note
If the key is brought within 0.2 m (0.656 ft) of the rear bumper, communication is not possible.
Tech Tips
When the electrical key transmitter is brought near the electrical key oscillator, 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 operation check is normal, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.

KEY DIAGNOSTIC MODE
| *1 | 0.7 to 1.0 m |
| *2 | Vehicle Center |
Diagnostic mode inspection (electrical key oscillator).
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
Turn the intelligent tester on.
Enter the following menus: Body / Entry&Start / Key Communication Check / Overhead + Luggage.
When the electrical key transmitter is brought within 0.7 to 1.0 m (2.30 to 3.28 ft.) of the outside electrical key oscillator (in rear bumper), check that the wireless door lock buzzer sounds.
Tech Tips
If the buzzer sounds, it can be determined that the luggage compartment exterior transmitter is operating normally.
