Hi,

Yes USBN9604 USB controller may be damaged .... but first : try to reflash microprocessor MB90F546GS (with nlc firmware or hardware method)

Hi,

Yes of course ! :-)

I measured the voltage of the legs.
All have 5 volts with the exception of 2.
Is this normal?

What transistors have to be:
n-channel or p-channel
T3 (4pin PIC) = 352A4 - p-channel ? (datasheet 352AP)
T5 (1pin PIC) = 352A4 - p-channel ?
T6 = Y2. - p-channel
7002 - n-channel

Thank you in advance for your answer.

-------------------
Replaced 3 transistors (T3, T5, T6) for p-channel. The voltage (PIC) at pin1-5V, pin4-12V.
Relays still do not work.

Help!.

Hello everyone,

I just bought a pp2000 interface, new one "chinese" that's flashed and detected by computer as revolution, it's a rev C.

Installed diagbox 7.02 but cannot communicat with my car, the green light stay on.

My car is 307 1.6 2006

I didn't test it on other cars... if i change the RAM can it work on my 307???!!

Thank you so much

Hi,

Hardware problem..... ! Post photos of PCBs?

Hi, this is the picture of PCBs.

I did a check with multimetre but there's no power on the second board. so i did check the connection between the two board and there's no power too. "i circle it in RED on picture"

That's mean that the problem come from the first board connected to USB.

Hi,

Relay PCB board take power of 12Vdc OBD plug (on car or on table power supply). And 5Vdc (always on relay pcb) is make by 2674 M5.0. Check this !
On microprocessor PCB board you don't have a good optocoupleur reference (Goods are : HCPL 063N and HCPL 0500), i don't see reference ? and some are replaced by transistors or 0 ohm...

Hi

For the 2674 M5.0. can you tell me how to check it with multim?tre. Must i connect to usb or to obd before cheking??

For optocoupleur there is just two:
9817A-2 and 500 515

Edit:
My car is 307 can.

Usbn9604 chip mounted on the motherboard only supports USB 1.0-1.1?
Bios on the computer is enabled to use USB1?
