OBD-2 ISO 9141-2 (14230-4, KWP2000) simple RS-232 cable schematic pinout
Components:
R1,2,6,7,9,10 - 560 ohm, 0.25W
R3,4,5,8 - 4K7 OHM, 0.125w
T1 - BC556 or 2N3906
T2,T3 - BC546 or 2N3904
One of our users reports that from collector of t1, r4 has to go to GND.
See also PC RS232 interface details.
Tx is -12V when inactive. therefore the diagram correctly shows that r4 goes to tx because it uses the -12V to pull down Rx when RS232 is in Rx mode.
