CHECK THE ENTRY UNLOCK FUNCTION

(a) Check the entry unlock function (driver door, front passenger door).

(1) Perform a wireless lock door operation to lock the door, touch the unlock sensor built into the backside of the front door outside handle assembly of the driver door while carrying the electrical key transmitter sub-assembly and check that the door unlocks.

(2) Inspect the entry unlock detection area. Hold the electrical key transmitter sub-assembly at the same height as the door outside handle assembly and approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the vehicle as shown in the illustration and check that the LED (red) of the electrical key transmitter sub-assembly blinks.

*a	0.7 to 1 m (2.30 to 3.28 ft.)

(3) With the system in unlock standby mode, grasp the front door outside handle assembly (for driver door) and check that the door unlocks.

HINT:

The system is in unlock standby mode when the electrical key transmitter sub-assembly is in the detection area and the key ID code sent by the electrical key transmitter sub-assembly matches the key ID code stored by the certification ECU (smart key ECU assembly).
Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the door outside handle assembly.
Inspect the front passenger door using the same procedure.

(4) Check the unlock response sensitivity. With the system in unlock standby mode, touch the area shown in the illustration and check that the door unlocks.

NOTICE:

If the sensor is touched too quickly or released too slowly, the sensor may not react and the door will not unlock.

*a	Unlock Sensor (Backside)

HINT:

Inspect the front passenger door using the same procedure.

CHECK THE ENTRY LOCK FUNCTION

(a) Check the entry lock function (driver door, front passenger door).

NOTICE:

If the electrical key transmitter sub-assembly is in the vehicle but outside the detection area (on the instrument panel, in the glove box, on the floor) and a door lock operation is performed, the key lock-in prevention function will not operate and the electrical key transmitter sub-assembly will be locked inside the vehicle.

*a	Lock Sensor

(1) With the door closed and unlocked, touch the lock sensor of the front door outside handle assembly of the driver door while carrying the electrical key transmitter sub-assembly and check that the door locks.

HINT:

If the door does not lock even when touching the lock sensor, touch it with your palm.
Inspect the front passenger door using the same procedure.

(2) Inspect the entry lock operating range. Hold the electrical key transmitter sub-assembly approximately 0.7 to 1 m (2.30 to 3.28 ft.) below the bottom edge of the door glass and approximately 0.3 m (0.984 ft.) from the vehicle as shown in the illustration, touch the lock sensor and check that the door locks.

HINT:

If the door does not lock even when touching the lock sensor, touch it with your palm.
As 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, the door may not lock if the lock sensor is touched with the same hand that is carrying the electrical key transmitter sub-assembly, etc.
If the key lock-in prevention function buzzer sounds, radio waves from the indoor electrical key antenna may be leaking from the vehicle.
Inspect the front passenger door using the same procedure.
The entry lock function cannot be operated more than 3 times consecutively.

*a	0.3 m (0.984 ft.)

CHECK ENTRY LUGGAGE COMPARTMENT DOOR OPEN FUNCTION

(a) Check the entry luggage compartment door open function.

(1) Perform a wireless lock operation to lock the doors, operate of the luggage electrical key switch while carrying the electrical key transmitter sub-assembly and check that the luggage compartment door opens.

*1	Luggage Electrical Key Switch
*a	0.7 to 1 m (2.30 to 3.28 ft.)

(2) Inspect the entry luggage compartment open operating range. While standing at the rear of the vehicle, hold the electrical key transmitter sub-assembly so that it is facing the direction shown in the above illustration at the same height as the luggage electrical key switch and approximately 0.7 to 1 m (2.30 to 3.28 ft.) from the vehicle, press the luggage electrical key switch and check that the luggage compartment door opens.

CHECK KEY LOCK-IN PREVENTION FUNCTION (IN LUGGAGE COMPARTMENT)

NOTICE:

In order to prevent the electrical key transmitter sub-assembly from being locked inside the vehicle, perform this inspection with the window of a door open.

If the electrical key transmitter sub-assembly is in any of the following locations, the key lock-in prevention function may not operate:

Near the spare tire or at the edge of the luggage compartment.
In a metal bag or near a metal object.

(a) Check the key lock-in prevention function (in luggage compartment).

(1) Place the electrical key transmitter sub-assembly in the luggage compartment with all doors locked. Check that: 1) closing the luggage compartment door triggers the wireless buzzer (which lasts approximately 2 seconds), and 2) pressing the luggage electrical key switch opens the luggage compartment door.

(2) Inspect the key lock-in prevention detection area. Pay attention to the direction of the electrical key transmitter sub-assembly shown in the illustration. When the electrical key transmitter sub-assembly is in either of the 2 locations in the illustration, check that: 1) closing the luggage compartment door sounds the wireless buzzer, and 2) pressing the luggage electrical key switch opens the luggage compartment door.

*a	Inspection Point

HINT:

Perform the inspection for both inspection points.

(3) Inspect the key lock-in prevention detection area and the electrical key and tire pressure monitoring system receiver assembly for wave leaks. Hold the electrical key transmitter sub-assembly at the same height as the lower edge of the luggage compartment door aligning it with the center of the rear of the vehicle. Pay attention to the direction and position of the electrical key transmitter sub-assembly shown in the illustration.

*a	0.1 m or more (0.328 ft. or more)

HINT:

If the wireless buzzer sounds, the No. 3 indoor electrical key antenna assembly (inside luggage compartment) may have a wave leak.
When the electrical key transmitter sub-assembly is over 0.1 m (0.328 ft.) from the rear bumper, the wireless buzzer does not sound.

CHECK KEY LOCK-IN PREVENTION FUNCTION (VEHICLE INTERIOR)

NOTICE:

In order to prevent the electrical key transmitter sub-assembly from being locked inside the vehicle, perform this inspection with the window of a door open.

(a) Check the key lock-in prevention function (vehicle interior).

(1) Turn the power switch off.

(2) Place the electrical key transmitter sub-assembly on a front or rear seat.

(3) Close all of the doors and make sure they are unlocked.

(4) Touch a door lock sensor and check that the doors do not lock and the key lock-in prevention function buzzer (external) sounds for approximately 5 seconds.
