E-09 Reset Behavior
The reset behavior of a component in its environment is simulated and tested.
Test boundary conditions (e.g. assembly, terminal, system) must be described
in detail. During operation, an arbitrary sequence of repeated switching-on/off
procedures occurs; this must not lead to an undefined behavior of the
component. The reset behavior is represented by a voltage variance and a time
variance. Two different test sequences are required to simulate different switch-
off times. A component must always undergo both sequences.
E-11 Start Pulses
When starting the engine, the battery voltage drops to a low value for a short
period and then slightly rises again. Most components are activated directly
before starting for a short period, then deactivated during starting and activated
again after starting when the engine is running. This test serves to verify normal
operation under these conditions. The starting process may be performed
under different vehicle starting conditions, cold start and warm start. In order to
cover both cases, two different test sequences are required. A component must
always undergo both sequences.
