Hi !

I bought a spare EDC16C39 (0281012298).

Now I wanted to readout with a clone BDM100 (UIFtech)

I dont use an BDM143.L or something, Ive made a connector where I can switch the leadpins easily.

When I click -ON- in Dimsport software there will be 12V on pin 2 and 9 of the 10p-cable. (p6 = GND)
Supplied to the ecu-board gives 5V on p11 of the ecuboard pads.
(later ECUs should give 3.3V)
I think the 5V must return to de BDM100 telling de ECU is active (sense), right ? if so which pin should I use ?

Who can tell me the correct wiring ?

What ecus have you doing?, Bosch ecu no need power supply.
