represents the ignition pulse signal of the four stroke engine;
The speed value shown is the engine speed value calculated
from the single cylinder ignition pulse signal. During the test,

coil of a cylinder, and not close to two or more ignition pulse
signal wires. If multiple ignition wires are arranged together, the

interface (the top of the machine). The “K line” identification
line connects the extension wire and probe; the “ground wire”
identification line connects the extension wire and probe; the

vehicle circuit (such as the 5 pin of the standard OBD-II), and
the K line probe is connected to the K line bus in the vehicle
circuit. Note to distinguish K lines on the automotive circuit. For
