View Full Version : Star Diagnosis C4 cables - coding resistors...

Hello Mates.

I lost three cables from my SD C4. Have only one, for heavy duty, 14-pin cable.

I had to connect one car, so I borrow 16-pin and 38-pin and measured
"SD-side 38-pin A-t" to MB 38-pin and to OBD 16-pin crossing. I made it.

I use 14-pin heavy duty 14-pin for obd 16-pin conector wiring, but DAS software
can't connect to car...

I measured once again my 14-pin cable, and discover 3,3kOhm between "T" and "U"
holes... It could mean that all SD cables are coded. Maybe someone could help me
and measure resistance between that pins in the rest of cables (38-, 16- and bananas-)
in "SD-side 38-pin A-t"
