Pre-Drive Check, Phase 1

In phase 1 of the pre-drive check, the igniter output stages are tested (with the exception of the high-side transistor, which is controlled via the alarm pulse).

During phase 1, no alarm pulse is generated. The sensors are stimulated and tested. On conclusion of this test the result is communicated in the control unit status telegram. An OK signal is only transmitted if all the tests have run without faults.

If any faults occur during the pre-drive check, these are stored in the fault memory.
