This test takes place in the Connection to the manufacture of the injectors. The deviations of the respective injection quantities from the setpoint. This information is sent to the injector given by means of a suitable data carrier. There are several Possibilities known. When the control unit is started up for the first time, the data read into the control unit in a suitable form and later for control purposes the internal combustion engine used. The injection quantity of the individual Corrected injectors by deliberately changing the control duration of the injector, that this measures the desired amount of fuel to be injected.

Recognize that Control unit or the control device that such a process is present is as follows proceed.
  • both the high-side switch and the low-side switch closed. This causes current to flow through consumer 250 as it is would also take place when the consumer is controlled for injection. It is provided that the control of at least one of the switching means, i.e. either of High-side switch or the low-side switch, so short that the current flow cannot cause injection, i.e. the control takes so long that the Consumers do not respond to the current supply.
