UTComp Pro without function

[Necro]

Hello all togehter,

i have the following problem. i installed the UTComp Pro in my car like the wiring plan.

A1 SW_GND
A14 SW_3
A3 SW_2
A15 SW_1
A4 DS18B20-A_GND
A5 DS18B20-A_DQ (signal)
A6 DS18B20-A_VCC (+5V OUT)
A10 DigInFc1 - FUEL CONS. SIGNAL (Injectior 1 Signal of a V6 engine)
A23 +12/+24V IGNITION
A12 GND (vehicle ground)
A24 +12/+24V BATTERY

So. When i plug in the big white Plug, nothin happens. Absolutly nothing. But everything is ok with the wiring.

When i plug in the USB cable, also nothing happens. But when i plug in the USB cable without the big white plug, i can connect to the ECU via Laptop and software. i also can programm the ECU. But when i plug in the big white Plug, it disconnected the ECU from the Laptop and nothing happens aganin.

I hope anyone can help me.

Thanks a lot.

Hi Necro. Please check your DS connections, if you swap A4 and A6 (vcc/gnd swaped = short circuit by external sensor) than it is overcurrent and module will not run. When you plug USB only (and ignition input is low) than power supply for DS sensors is disconnected. Just try to disconnect DS inputs and try to run it. Hope it helps (if it not helps, than something is wrong with module and shipping may be required - but we can resolve any issue so dont worry).
