Functional Description
1. General functional description
This short system description gives an overview about the functionality of the Keyless
Vehicle (KV) system and from the Keyless Vehicle Module (KVM).
The vehicle and the Passive Key (PK) will communicate via challenge / response.
By any request the KVM sends a challenge via the respective Low Frequency (LF)
antennas with 125 kHz to the Passive Key. The PK’s within the detection range answer with the identification code via Radio Frequency (RF) transmission. The
external RF Receiver sends the data from the received signal via serial link to the
KVM.
2. Passive entry, passive exit
2.1 Unlocking
With a valid PK within the outside detection range of the vehicle, the customer will be
able to open each door of the passenger compartment and the tailgate.
Woken up by pulling a door handle the KVM sends a challenge125 kHz via the corresponding inductive door handle antenna to the Passive Key. After receiving the
challenge data the Passive Key sends the response data via RF to the external receiver. If the identification code received is valid the KVM sends the unlock request
command via CAN-Bus to the Passenger Junction Box (PJB).
2.2 Locking
To lock the vehicle, the customer has to push the Lock Button mounted in any door
handle once and a valid PK has to be detected within the respective door handle detection range.
3. Passive start/stop
The KV system will provide an inside detection range, which will cover the passenger
compartment.

3.1 Engine Start / Unlock of Steering Column
The starting action will be handled via a rotating Ignition Switch, which provides ignition off, accessory, ignition on and crank position.
With a valid Passive Key within the interior detection range, the customer will be able
to start the engine after pushing the brake (automatic transmission) or pushing the
clutch pedal (manual transmission). After detection of a valid Passive Key the KVM
sends the release command to the Smart Steering Column Device (SSCD) via which
fulfills a mechanical release and permits the customer to rotate the Ignition Switch to
any position (ACC, Run, Start). Without detection of a valid PK, the Ignition Switch
and the steering column remains locked.
The Engine Control Unit receives authorization to start engine from the KVM via
CAN-Bus from the Cluster module.
3.2 Engine Stop / Lock of Steering Column
For Engine Stop the Ignition Switch must be rotated to ACC position.
