System description
The IMM is designed to prevent starting the main engine and moving of the vehicle without a valid
key. The Driver-ID & Immo inhibits the starter motor by interrupting the connection between
ignition lock and starter with a high side switch (HSS) and blocks the gear box via CAN
communication to the VDC (vehicle drive control).
Each Driver-ID & Immo comes with a factory paired master key. With this key starting the engine
is not possible but teaching user keys. The owner of the fleet is able to teach and delete user
belonging keys to different vehicles with the ignition lock inside the cab (BASIC mode) or via a
fleet management software running on a farm PC (REMOTE mode).
All keys are equipped with up-to-date RFID cryptographic transponder to ensure secure operation
and protection against misuse.
To increase the security level the Driver-ID & Immo once installed in a vehicle automatically pairs
with the VDC and finally can’t be used with different VDCs anymore. The communication is
AES128 crypted.

Functional description
The IMM module IMM function is based on application of master and user keys combined with the
communication to other modules. Only one master key is valid for each IMM which is paired at
CLAAS production. For security reason the master key data are stored inside the microcontroller’s
E²PROM. Up to 50 user keys can be taught to each IMM and will be stored into the external
E³PROM (see chapter „Teach-In procedure“).
The IMM starts working on turning a key in the ignition-lock. Transponder reading is directly
started to check for a valid master or user key for about 1.5 seconds, CAN transmission is
disabled during this process. In case no transponder is found the IMM waits for deactivation of
clamp 15. If a valid user key is detected, the IMM waits for signal input on clamp 50 and then
activates clamp 50 output (HSS 1). At the same time CAN authentication procedure with the gear-
box module (VDC) is started and after successful CAN authentication HSS 2 is activated. In case
clamp 50 becomes active but clamp 15 isn’t any more, the IMM switches off.
If an invalid key is detected, all actors are deactivated and no authentication process to VDC is
started. Cyclic CAN state messages inform other bus members about the actual IMM status.

Vehicle keys
To the Driver-ID & Immo generally belong two kinds of keys with different color, different key
identifier (MASTER / USER) and always unique transponder IDs. The mechanical cutting is
uniform for the customer fleet.

The green key is the master key and paired to a specific IMM irrevocable during the vehicle
production in line. With this key starting of the engine is not possible by definition but teaching and
deleting user keys to the IMM. In case the master key gets lost the IMM has to be exchanged and
disposed. A maximum of two master keys with equal rights are valid for each IMM.
The black key is the user key which belongs to a fixed driver and not to a specific vehicle. The key
can easily be taught to different vehicles within a fleet and also deleted. The assignment can be
done directly at the vehicle or dynamically managed from the farm PC via remote access. The
user key comes with a plastic tab with TBD information on it and a number calculated from the
CLAAS secret key, unique ID and key identifier. The number will also be available as a bar code.

interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures: -Reorient or relocate the receiving antenna. -Increase the separation between the
equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected. -Consult the dealer or an experienced radio/ TV technician for
help.
(Section 15.21) CAUTION: Any changes or modifications not expressly approved by the grantee of
this device could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
