Sirius 32

[dadal]

Ecu is immo off ( I test it on car ) but I want to test it on bench to know immo is OFF or ON.
connection : pin 29 + 30 + 66 12v 3+33+28 to Ground I measure ''0 volt " on pin 68 ( fuelpump ) , and "0 volt" on pin 1 + 32 ( ignition coil)




other values are good. pin 68 must indicate 12 Volts ,,immo is OFF but I measure 0 volt . I must use a relay ?

How can I This ecu on bench test ? I dont have Clip, and DDT.....safir 1-2 are easy, I can test it with a simple 12volt lamp but sirius is not same
thanks
