Internal Antennas
There is a total of three internal antennas. The internal antennas are under the carpet:
- under the center panel
- between the center console and the rear seat
- in the cargo compartment.
The antennas allow the keyless vehicle module (KVM) to communicate with the passive remote key. The keyless vehicle module (KVM) activates the internal antennas in the event of any of the following:
- a signal is received from the contact breaker when the starter button is pressed in
- a signal is received indicating that the brake pedal (automatic transmissions) or clutch pedal (manual transmissions) is pressed
- a lock command is received from the remote key
- a lock button at one of the external door handles is pressed in
- the first switch in one of the external door handles is closed
- a request to check the remote key from the central electronic module (CEM).
The antennas are also activated when the vehicle is locked. This to deactivate any remote keys which are still in the vehicle. This is so that the vehicle cannot be passively started/unlocked by any remote keys still in the passenger compartment. The remote keys are reactivated when the vehicle is unlocked or when the button for unlocking is pressed on a deactivated remote key.
The keyless vehicle module (KVM) checks the internal antennas every operating cycle if the vehicle speed is in excess of 20 km/h (12 mph).
The antennas are powered by the keyless vehicle module (KVM).
