ECCS control unit connector pin assignment
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.). Given- the data provided are standard values.
Note: There are sensors that use the ECCS control unit housing for ground, so if the ECCS control unit is removed from the vehicle to check the parameters, be sure to connect the unit housing to ground.
The voltages shown above are the values measured by an analog tester.
