() The names of the signals on the contacts of the diagnostic connector are indicated (sR motors do not use RX and TX contacts).
Standard input/output voltages of the ECCS control unit

Measurements are carried out using an oscilloscope and a tester.
Below are the voltage values measured by the tester at the ECCS control unit contacts and the oscillograms.
Measurement data varies depending on the main factors (operating mode, environmental conditions, service conditions, devices used, measurement methods, etc.). The data given are standard values.
The voltages shown are values measured with an analog tester.
