I have been trying everything in my power to figure out why my OBD port is not working. Has the bright light on the gas and the speedometer not working. I try my best to look for any grounds in the dashboard wire hornist I don’t have a wire hornist I don’t have any fuses blowing on the hood name on the steering wheel? I don’t know what else to do so anybody help me or leave me in the right direction thanks!!

 

Anyone?

 

You post this at 5:23am on a Sunday morning and you expect help right away? oof

Your description is poor. What is the main issue? Brake light is on? How does the car drive and behave?

 

Yes, it drives ok i guess and my obd port does work I connected my code reader and it doesn’t have power.

 

 

Why that picture

 

Again, what is your main problem?

Is the car on (but not running) when you say the OBDII port has no power?

 

Yes, it’s on the on position

 

I mean problem is that I can’t get my code reader to connect to the car

 

yes

 

yes car on not running and yes OBDll has no power when I connect my code reader. Trying to figure out how to get it back working.

 

Check out this thread. There are two good suggestions within that worked for other Maxima owners. Let us know if you fixed the problem.

neither of those suggestions worked 😞

 

Have you tried using the Search function? I recall a few threads about this issue.

 

Yea

 

Did you try connecting your code reader to a different vehicle to see if it works?

 

Yes I had and it connected

 

So now is the time to brimg out a voltmeter or test light. Test pin 16 to a good ground. If power there, then check between pins 16 and pin 4. Most likely this will show 0 volts. If no power to pin 16, you have a wiring or connector issue. You are just going to have to use your tools and Mark 1 calibrated eyeball to track it down

 

Are you turn on ignition before you connect obd reader (foot brake relased)?

 

yes

 

Any background info? Since when did the scan tool fail to communicate with the car? Any repairs before?

 

Can't agree with you more.

 

I’ll say like a month ago I had it hooked up and it cleared a i’ll see you like a month ago I had it hooked up and it cleared code and then next to you know stop working

 

You know where or wat section of the car to start looking or you know where u can a diagram?

 

yes I have power from the 16 pin sir

 

Since you’ve tried your scan-tool on a different OBDII vehicle, how about trying a different scan-tool on this vehicle?

 

Check that the connector pins on your tool are not bent.

 

Not a bad idea.
