Rear Electronic Module (Rem) Connectors A-E
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)
