Vehicles equipped with the hands-free system have presence sensors and door opening antennas for card recognition:
- – door opening antenna in the outside handle of each door,
- – door opening antenna in the rear bumper,
- – door opening sensor in the outside handle of each door.
Fig. Door opening antenna arrangement: 1 - opening antennas located in the outer door handles, 2 - opening antenna located in the rear bumper, 3 - engine start antennas.
The engine start antennas do not affect vehicle unlocking.
Conversely, it is impossible to lock the vehicle using the "lock" switches located on the outer handles if the card is in the engine start zone.
The motion sensors are built into the presence sensors.
Removing the antennas
For hands-free operation, the outer door handles are equipped with:
- - presence sensors for recognizing the user's hand in combination with a reflector mounted on the handle;
- - a lock button;
- - an opening antenna built into the handle (Fig. 2)
Fig. Door opening system components: 1 - sensors, 2 - lock button, 3 - opening antenna.
Only vehicles equipped with a hands-free system have a lock switch.
If the vehicle has not been used for approximately 72 hours, the occupancy sensors are disabled.
In this case, the unlock command is detected by the handle movement sensor.
The occupancy sensor and handle movement sensor are assembled.
Removing the rear antenna
Fig. Rear antenna appearance
Remove the rear bumper.
Disconnect the antenna connector and remove it (Fig. 3)
Installation
Installation is the reverse of removal.
Fig. Opening antenna connection connectors: A - connection contacts, 2 - connector 1, 3 - connector 2
Opening antenna connection
Presence and motion sensors (connector 2):
- Contact 1 - Sensor signal;
- Contact 2 - ground;
- Contact 3 - Supply voltage ("+" before ignition switch)
Opening antenna and locking switch (connector 3):
- Contact 1 - opening antenna;
- Contact 2 - opening antenna;
- Contact 3 - locking signal;
- Contact 4 - ground of the locking sensor
NOTE
Switch The locking is checked with an ohmmeter, connected to contacts 3 and 4.
The opening antenna resistance value is approximately 0.2 ohms.
