Need help OBD port has no power.. anyone know where the OBD port fuse is or what fuse shares power with the OBD port any help would be appreciated!!!!

 

man i have the same problem i was looking into this a few months ago and decided to leave it alone but not im in the process of getting the uprev tuner and i need help.. where is the fuse?? someone must know

 

iv read somewhere that the clock and cig lighter are running off the same circuit as the plug, but my clock is working fine, my cig lighter works however i need to move it around a bit.

any recommendations?

OP does your clock and cig lighter work???

 

Yah I can't figure it out my clock and the cig lighter works fine... I'm stuck in the same boat was try to get retuned and my tuner can't get in to the ECM cause the OBD port has no power...A friend told me it's the fuse but I can't find where it's located....

 

I was just looking around for this the other day. Have TPMS light that won't go away. Where in 808?

 

In case you do not know, there is a fuse box behind the battery, i would check there if you haven't,

 

I have an 08 sedan there's a 10 amp fuse labeled battery/electronics I had the same problem took me months and replacing that fuse fixed it along with my clock that wouldn't work not sure if yours is the same but trying to help

 

Sorry it's an 07

 

It's most likely the same as the 08.

 

Well idk because 07 are the "new" body style remember the body the g37 sedans have now is more likely to be the same but then again why change fuses around when people keep having this problem

 

Hey man im looking for that fuse on my 07 gmyx. Where can i locate it.

 

Sorry, what's a gmyx? You can find factory service manuals here:

Click the model, scroll down click the model again, click the body style, click the year ... look for "Power Supply, Ground and Circuit Elements" - click on that, then scroll down below the viewing window and "Click here to download a copy".
