In the following example, there is a short circuit between the positive coil connections of coil 1
and 2.
Figure 3-4.
Taking the circuit situation shown above, the test run starts with both S_L1P and S_L2P
switches closed (default state when entering the diagnosis mode for the first time). The
read-back of the line state result in both times 0, which is not unexpected. However, the result
does not change when either altering the channel 1 or the channel 2 switch setting. That can
be caused both by the failure shown above and by short-circuits of both lines to ground. The
final diagnosis can be identified by changing both channels to the high-side switches (S_H1P
and S_H2P). In this case, the two status lines both return 1s – which eliminates the possibility
of two short-circuits to ground.
Table 3-2
summarizes this test sequence.
