ECU Z16XE

look post 24 - 4pcs ignition IGBT , sometime the problem is deeper - not repairable ...

Well ,there is a small burn om that ground trace..using some sharp needle I was managed to confirm that 1 and nr 3 transistor are for ignition (this is a waste spark system) .So there is continuity from outside of ECU to transistor ,also spark from bad output for a few minutes .Could that burn on the ground trace cause the problem ?
See maybe can put some solder there and come back with results...

How can be chemical removed the silicone gel?

Same question and one more:is the white board of Vectra ECU harder to repair than blue board from Astra ECU ?I have 4 Astra repaired but first from Vectra seem to not solder at all .For Astra just solder paste and normal Pb/Sn solder and copper wire and after two hours job is done ,but for Vectra after two days half wires soldered and half wires fail to solder ,even with 125 degrees preheating plate

you have to solder new wires no old al wires ,it is soldering normal with 350 -380 C .we do it hunderd times,for ignition coil if you have eror for all ignitions 1-4 problem is like on picture (that is resistor ) ,only solder about 2mm where is resistor broken.two black lines is laser factory calibration of resistor

Any chance on a ECU with APP sensor 2 low voltage ?Voltage checked good with scope on the ECU conector ,but ECU see 0 volts on sensor 2.Wire to the PCB good also...

Hi, can anyone knows what type of transistor is this? I damage when open the ecu with a screwdriver. Without it I cannot communicate with ecu anymore. I try to replace with a standard n channel cmos transistor, and I can communicate again with ecu, I manage to erase all errors but when I try to start the car the ecu cut off the communication with the car and cannot talk with it until I off and on the ignition.

Seems to be a transistor.

[volorucinski]

I will cut the wires from the pcb and measure again this evening. Hope to get an exact measurement

[TR0UBLESH00TER]

As far I can remember it was a 9 volts regulator ???Better to measure live i a working ECU

[volorucinski]

The LDO isn't on the opposite side? In the right corner?

[volorucinski]

Here is what i have. Three different measurements and if i remember well, on the top capacitor, there are ~8.6v, as the LDO sends and on the lower capacitor there are 5v.

And the picture that couldn't be uploaded first time
