The instrument can directly drive the injector for testing, and
can also detect the real-time injector signal of the vehicle;
Insert the multi-function detection line into the multi-function
interface (top of the machine), connect the battery clip line,
clamp the red clip on the positive plate, clamp the black clip on
the negative plate, and connect the removed injector to the
multi-function line, as shown in the figure below:

During the vehicle start process, the minimum battery voltage
is detected above 9.6V, indicating the normal state. If the
lowest voltage is below 9.6v, indicating the low voltage. The
possible reasons for low voltage are battery aging, large
mechanical flow, etc. It is necessary to further check the corre-
sponding components, among which battery aging is the most
important reason.
