Signal Specification

Driver door module / passenger door module connector A







Connector A, terminals #A1 #A30
The following values are measured between the relevant terminal in column 1 and terminal #A6 (ground) unless otherwise stated. The values are measured with the control module in "Active mode".


NOTE: Check the ground terminals as above before taking readings using the breakout box.


U = DC in volts (V).
Ubat = battery voltage in volts (V).
Ulow=Voltage close to 0 V.







Connector B, terminals #B1 - #B12







The following values are measured between the relevant terminal in column 1 and terminal #B9 (signal ground) unless otherwise stated.


NOTE: Check the ground terminals as above before taking readings using the breakout box.


U = DC in volts (V).
Ubat = battery voltage in volts (V).
Ulow=Voltage close to 0 V.
