Diagnostic port no power detected

Hi,

I attached the wiring schematic which includes the power supplies to the data link connector. As far as the fuse you checked, I think it was the wrong one. You need to check fuse 1 in fuse holder B on the left side, under the dash.

When you check the fuse, do two things. First, confirm the fuse is good. If it is, then confirm there is power to and from it. Here is a link you may find helpful.

Also, if the fuse is good and has power, then go to the data link connector and confirm there is power getting to pin 16. (See pic 3). Pins 4 and 5 should have continuity to ground, so check that as well. Here is a link you may find helpful:

Let me know what you find or if you have other questions.

Take care,

Joe

Note: The wiring schematic had to be cut in two to make it readable for you. I did overlap the two so you can follow from one to the next.

Thank you very much for the reply, after all this, it was the fuse that you mentioned. The pin was recessed in the harness therefore not making contact. Thank you for the help and the diagrams.

Hi,

Thank you for the update. I'm glad you found the problem and got things working again.

Please feel free to come back anytime in the future. You're always welcome here.

Take good care of yourself,

Joe
