I have built the V3.1 circuit interface obd/serial, and using Scantool v3 or v4 can connect and read the motronic values, but nothing else (no air bag, climate, or ABS) on the '93 RS America. The L line is polling - I can see the LED, but nothing from K.

Is anyone aware of any differences of the RSA DME, or something I have to change in scantool.cfg?
