C4 multiplexer 10 minutes countdown

RE: C4 multiplexer 10 minutes countdown
Thanks Guys

About cables i don't think so becuase the problem is with obd and with 38pin cable too, so i don't believe are both faulty.
I will flash it with new software now as i will upgrade version and after i will open and check the board inside.

I would not do this. Better fix the hardware first and later update.
If you like to play with fire...go for it.

What about to be Software problem, or just a new flash to fix it?
No chance about it?

Thanks

Sincerely, if it was a software problem there will be more errors than this. I really believe that is a hardware issue.
If your cables are good the next step would be checking the small PCB with round connector.
Look carefully at what JarsaR said in his post. Soldering on these units is so poor that many times those connectors are not even soldered. They have just 2-3 pins soldered which still keeps connectors in place but all other pins are just touching the pads without being soldered.
You can check this easily by trying to move a little that connector. Use a magnifying glass and you will easily notice where the problem is.
Also ROUND CONNECTOR! That one will break solder points on his pins.

Hey,

I hope you will eventually solve this, and hope you will update the outcome.
I have never seen behaviour like this. But small hint for soldering those pads, (If it is yanhua mux) Do not Shake remove the whole pin like i did, it is very difficult to aling with the round connector board. Just get small tip for soldering iron, even grind one if you have to! Nod

RE: C4 multiplexer 10 minutes countdown
Marcos is right.

Do not update or what so ever. If this is a hardware issue and for whatever reason decide to go off while flashing you might end up in a really bad place.

Fix your board first. I had a few people bringing me their muxs just to check if i can do something.
Managed to fix 1 out of the scrap from the other 3-4 that were here. 2 of them had broken pins and board for round connectors was fried, literally. You could smell the awful burn from 10 meters away.
One had shorted some SMD resistors under the round connector. Trust me, not a 5 minute fix to install new ones (if you are lucky to have some). I used some from the two that were trash. Not sure if that one finally worked or not. But yeah, the last one had the screen faulty. Just used one of the scrap ones. That was an easy fix.

Or just buy a new one and be done with it.
