When I plug in my basic obd2 reader, it turns on but error no communication. I've checked the connecter ports and wiring around the back looks clean. I have 10 wires going into it of which 1 k-line, ground (4 and 5), power 16. The others are (I think) 3 TNA, 7 K-line, 8 Ignition, 9, 11, 12 K-line. No Can hi or Can low, is this normal? Can it communicate without these connections?
