voltage of the signal line should be 1V lower than that of the battery. (if the voltage
of the vehicle’s power supply is 12V, the voltage of the signal line should be about
11V±0.25V. If the power supply is 24V, the signal line’s voltage should be
23V±0.25V)
4. If CAN communication is adopted in the communication of the duel signal lines, turn
on the ignition switch and measure the voltage of the ground line via multi-meter.
The total amount of the voltage measure through these two lines should be 5V. The
voltage of CAN-H line should be 2.50.25V, and the voltage of CAN-L line should
be 2.50.25V. There might be a deviation with its value being from -0.25 to +0.25 in
cases of actual measurement.
