Abstract:
1. A starting device for an internal combustion engine, having a switching control device for controlling a starter motor, the switching control device comprising: at least one power switching module which connects the starter motor to a voltage source, and which is activated via at least one control line assigned to at least one of: i) the at least one power switching module, and, ii) at least one control stage assigned to the at least one power switching module; control electronics configured to control the at least one power switching module; a release device which records a power flow of the internal combustion engine, and which is configured so that, when there is no frictional connection between the internal combustion engine and a power train assigned to the internal combustion engine, the release device makes available, on a release signal channel, a release signal for releasing an activating switching procedure by the at least one control line, the release device including a first release switching channel working independently of the control electronics, and a second release switching channel working together with the control electronics, the first and second release switching channels being configured so that an initiation of the activating switching procedure takes place only during simultaneous release switching setting of the first and second release switching channels; and a diagnosis device which is configured so that, at an ending of making available the release signal for the activating switching procedure by the release device, the diagnosis device records a switching setting representing a release switching setting of the first release switching channel.
