<p>The invention comprises a theft-impairing device (1), intended for a motor vehicle, which utilizes an ignition lock (2, 3), a control device (4) and a code identification unit (5). A through-voltage connected via the ignition lock (2, 3) can be supplied (10) to the control unit (4), which is so arranged, given the fulfilment of certain selected conditions, to supply voltage to at least a starter motor and a drive unit (8), belonging to a fuel and/or ignition system (13, 14) for the engine. One of these conditions is that the control unit (4) has received and approved a signal generated by the code identification unit (5). The drive unit (8) belonging to the fuel and/or ignition system is connected to the control unit (4) in order, depending on an activation signal generated in the control unit (4), to allow voltage to be supplied for the activation of functions in the drive unit (8), whereby another of the conditions mentioned is that the control unit (4) has received and approved an acknowledgement that the activation signal mentioned has activated functions inside the drive unit (8).</p> |
