Hi Huys, I recently bought a 2015 Hyundai Sonata 1.6 gdi.
When I connect the obd to the reader (Creader vii+), it gets power from the connector but there is no communication possible. I have tried the Creader vii+ on my Mazda as well and that works.

What can i do to solve this communication problem?

Attached is a photo of the obd connector, top left is pin 16 and bottom right is pin 1.

I hope you can help me!

You need to plug in OBD2 when ignition is off, then turn the key to on but don't start the engine. If OBD is still not working, clean the ECU negative terminal, which is ground wires tighten on the engine or car body

Ground negatieve seems to be ok, no corrosion and I have tightened them. Still no communication though.
There is power because the device turns on when i plug it info the obd, ignition is on andere the vehicle is obd compliant.

Are you connecting the scan tool to diagnose a problem? If so, could the problem your trying to diagnose be related to the failure of the communication bus?

No there is no specific problem to diagnose, the only reason for me to connect is because the dealer tried to connect to obd and they said they could not communicate. So now I am trying to find out how to solve this.

There should be +12v on 4, 12 and 15 with the key on engine off. 1 and 5 should be the grounds to check the voltage against.

Was the dealer tool able to communicate with any of the other vehicle systems?

Sounds to me like there might be a problem with the CAN link to the OBD connector, so you might want to measure the voltages on the CAN terminals of the connector. That'll be terminals 6 & 14.

Thanks. @Red Raspberry: I will check pins 4, 12 and 15 again 1 and 5 and report back on this. @AUTOSPARK: pins 6 and 14 are empty on the obd connector.

Should pins 6 and 14 have cables on a 2015 Hyundai Sonata? The obd connector looks not tampered with.

Yes, that's where the CAN BUS wires should be which explains why you have no comms with the engine PCM.

You might want to ask Red Raspberry to confirm where you are to measure these voltages. They aren't correct for the OBD connector.

I will check it this weekend.
Does anyone have the colors regarding the cables that go to each pin of the 2015 Hyundai Sonata obd connector?
