RE: Help! C4 Mux not power up when connect to car with cable, but power up with battery
If you look on ebay UK, you can buy new m
PCB power boards for about £60 which will be a complete new end with new lan cable and 36pin connector too.

Very quick to swap over clapping

I am sure the power from the vehicle is working, because i borrowed a C3 from a friend to diagnostic the vehicle after the C4 is not working.
And I have tried with another OBD2 cable between the car and MUX, but same result, the Mux would not boot up. tears
I thought the Mux was totally dead, but when I get home, I tried to put in some battery to the C4 Mux, then the Mux boot up without problem, but I have not try if the Mux could communicate with the vehicle through the obd2 cable.

Does any body know what's wrong with it & how to fix it?


Seems that one of green fuses on front connector pcb is gone.

It can be repaired, no probs (if all other is OK with that SDC).

Regards!

Thank you for your advise.
