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 an-swer 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 cor-responding 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 re-ceiver. 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 de-tection range. 3. Passive start/stop The KV system will provide an inside detection range, which will cover the passenger compartment.

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. 4.
