Connector A, terminals #A1-#A20
The following values are measured between the relevant terminal and terminal #E1 (power ground) unless otherwise stated.
The values are measured with the control module in "Active mode".
Note. It is important to connect the breakout box and check the ground terminals before taking readings.
U = DC in volts (V).
Ubat = battery voltage in volts (V).
Ulow = Voltage close to 0 V.
NC = Not connected
NC* = grounded via capacitor (C=22nF)
