Is there power to pin 16 on OBD2?

It can do strange things. Yes I have power to pin 16 (the power to the scanner) I also have good grounds at pins 4 and 5. Pin 2 (which is the signal from the ECU) has very low voltage. I’m using a good OBD2 reader that works on every vehicle I’ve ever used it on.

Is there low voltage to signal wire pin 2?

There is very low voltage to the “signal wire” pin 2. It should be 5 volts but it is 0.3 volts. This site shows a lot but I don’t know what the diagram means S1 through S9 or whatever. Where are these splice bars located and how in the world do I do the tests they suggest?

What does pin 16 on the ODB-II connector mean?

Pin 16 on the ODB-II connector is specified as “Battery Power” or “Battery Positive”. There will always be 12v power between pin 4 and 16. Note that pin 5 has “ground” in the description, but that is just for the communication signalling and not for power.

Why do I get No reading on my OBD codes?

Check your fuses to see if any have gone bad. Remember that your car or truck might have more than one fuse box. This should be covered in your owner’s manual or a proper service manual. Another reason for getting no reading is that the scan port has become clogged with dust after years of not being used.
