Cant inspect becuase of cig lighter fuse obd computer?

check fuse for cig lighter i believe (for whatever reason) GM tied the radio cig lighter and obd II fuse together

check the fuses such as cig lighter //acc and or harness to obd port for damage or short but usually blown fuse is problem

It's under the hood. Fuse #32.

The OBD2 receive power from the cig lighter fuse. Sometimes coins or other metal fail in the lighter.remove phone chargers lighter and inspect the socket for debris.If nothing inside unplug the lighter,inspect the truck and find replacement socket.
good luck

Sometimes the problem is a blown cig lighter fuse if you are using an OBD 2 scanner.

Yes.
The OBD connector for the scanner is powered by the same circuit as the cig lighter. If the fuse is blown, the testing facility can not access the computer on the car.

check your cigarette lighter fuse that fuse usually powers your computer port

often times if you fix the cig. lighter (replace fuse) you will be able to read obd. uses power from that fuse to power up scan tool. make sure no pennies or anything in cig lighter blowing the fuse.

you could do this by running 2 wires directly from the battery to the back of the cig lighter and by fusing the positive.if it is only when using the cig lighter and not when charging a phone ect.it could be element on the cig lighter shorting

you most likley have a blown fuse. the fuse for the connector and cig lighter are usually on the same circuit . if you have a owner manuel check and see which fuse is for the obd/cig lighter. if you dont have a manuel then check every fuse in the box and see if you find a blown one. the plug whare the scanner connects is what powers the scanner so if you cant find a blown fuse then you know youre not getting power to the plug for some reason.
