Broken Radio, OBD Port also not working


Recommended Posts

Hi, I recently got vcds and wanted to check my car with it, it showed me that K1 and K2 have no power, I checked the fuses and they all seemed fine.

I read that sometimes it's the diagnostic cable for the radio on aftermarket head units, took out the radio and the cable was already removed. Put it back in and now the radio won't turn on. 

Checked the fuses again and they all seem fine too. So I used a multimeter to check the ISO ports

pin 4 and 8 show 12V with ignition on

Pin 7 and 8 should be battery plus but I get nothing, 0V

What could be the cause for this, I did try jamming the radio when I put it back in because it wouldn't fit with all the cables in the back but how would that kill the battery plus. 

Does anyone have any advice.

Okay, I fixed the radio. 

However I still can't get my hex v2 to get power, my cheapo obd2 Bluetooth adapter does get power but can't connect to the car. 

My assumption is that the Hex V2 adapter is too big and doesn't fully insert into the port, can I remove the port from its position and pull it out slightly? If so how?

You could add some washers to either push it down or angle it? Does your Hex work in other cars ok?

Lupos use the k line for data with the standard power supply connections. So it should work. The power pins are different lengths to the others, so it is possible that the unit isn't pressed into the socket properly.
