Immobilizer:
Direct connection to «Immobilizer 2» wire of main OBS cable tree:
The immobilizer output «Immobilizer 2» (main cable tree Pin 1, green wire) contains a self
protective FET to connect a wire to ground, e. g. the wire from the start button of a the car can be
connected to ground via this wire. The OBS will switch the ground connection off in «logged out»
state to immobilize the car then.
Breaking a wire via immobilizer relay:
Cut a dedicated wire of the vehicle harness to immobilize of the car (e.g. the wire to vehicle starter
relay) and connect the 2 ends to the switch of the relay. Connect one wire to the «normaly open»
contact (NO) and the other to the «common» contact (C) of the immobilizer relay. Connect one
contact of the relay coil to 12V and the other to «Immobilizer 2» output of the device (Main cable
tree: Pin 1. Green wire). Attention ! The relay needs 100 mA, if th immobilizer is released. If «Key
detection mode» is enabled or «Automatic log out» is disabled by configuration, the relay will drain
100 mA during the whole time of a trip, even if the user is logged out. This could drain the car
battery. To avoid this, connect the relay coil to «12V ignition on» (K15) instead of «12 Volt
permanent» (K30) or use a «latching relay» .
Connecting to CAN bus wires of the vehicle
Wires to the CAN bus must be twisted. Connection to CAN-Bus must be realized with twisted
wires. The cable lenth shall be as short as possible, cpecially, when connectiong to high speed
CAN bus (500 kB/s).
Soldering a cable to the remote key electronics
Optional, Only needed, if not connecting central lock actuator lines to vehicle harness
Attention: Opening the housing and soldering the cable to the remote control print is
delicate. Convadis is offering a service to connect the cable for you.
