3.3 Passive Entry and Passive Start
3.3.1 Passive Entry
Passive entry process is the authentication of the PK and BCM to enable unlocking
and locking of the vehicle among other functions requiring a PK search on the
interior of the vehicle.
The vehicle can be unlocked or locked as follows:
- Trunk open function: PK shall be on the outside rear of the vehicle
- Trunk close: No PK inside the trunk OR if there is a PK inside the trunk, the vehicle
shall not be in the armed state.
- Right side entry/locking: PK shall be on the outside right of the vehicle
- Left side entry/locking: PK shall be on the outside left of the vehicle
3.3.2 Passive Start
The Passive Start process is the authentication of the PK and the BCM for enabling
the power pack.
For the Passive Entry Passive Start, key authorization time must be less than or
equal to 285ms from the initial customer start command to sending the authorization
to the BCM
3.4 Mechanical key
Key blade is inside the key.
3.5 Remote Keyless Entry function
When a button is pressed, the microcontroller wakes up and calculates a unique telegram,
which is sent to the vehicle by modulating an RF oscillator. The telegram contains the
information, which button is pressed.
After transmitting (buttons released) the key returns into sleep mode to save battery power.
3.6 Transponder function
The transponder function is part of the immobilizer system and allows authenticating the key
and starting the engine independent from the key battery voltage level.
For that the key will be inserted in the ignition lock with immobilizer base station. The
immobilizer base station will charge the transponder with an LF field and send an
authentication request. After having received sufficient energy the transponder will answer
the request. This is recognized by the immobilizer base station and decoded. If the data
stream transmitted by the transponder fits to the expected data stream the immobilizer base
station will send a start engine message to the engine control.
