OBD scanner-no power ?

[cj5orion]

98 ram 1500 5.9 mag,auto,4 whl

check light is on.
no power to scanner plug ?

fuse ?
could it be one of these ?
the 20 amp under the hood WAS blown...but ? whats it control ?

any body else had no power to the scanner plug

IN the first pic,theres 3 fuses with the "extra" brackets on em,the black one and 2 yellows,only got em partially out,couldnt check the fuses

Yes that can do it. Check all of your fuses. You probably blew the fuse that powers your OBD2 plug. Just had it happen recently on a Silverado we were fixing.

Usually it is the cig lighter circuit that powers the obd plug

 

[ADudeOnSkis]

Yes cig lighter fuse. Rather dumb on Chryslers part to not label it...

 

[cj5orion]

Thanx much guys !
I've been hiding my tags all week from the metermaids !!!
tags expired at Aug end.
fuse to cig lighter is good,but lighter is out as well.
I'll rip into the dash and check it out,see if I can get that obd port fired up
NOW I KNOW WHERE TO LOOK !!!!!!!

 

[cj5orion]

OK ...found the prob
a "aftermarket" fuse box gave up on me.
installed it when I had issues with my cig lighter.
the fuse is good but not sending power downstream,jus plugged in to another terminal...all good

NOW....i DID A FORUM SEARCH FOR READING CODES...couldnt find anything ?
anybody got a "http" for the codes ?

 

[Merc225hp]

yea look in the tech info area here on rf in this section.

 

[cj5orion]

well I thought I found the problem...cig lighter has power now but still no power to OBD ?

My "online" service manual is not loading for some reason ?
question
which pin in the port is the power pin ? ( for voltmeter testing)

 

[cj5orion]

got a service manaul to work.
scanned all 2000 pages....no info about obd port

On the 98 Ram its fuse 12. Same as dome, cargo, glove box & under hood lamps. The yellow & black keepers are used to pull the fuse loose. Theres a little "flip open" spot or door on top of it that then gives access to remove the fise. Hope that helps, took me a bit to fig both these out! Which was OBD port fuse, and how to remove it!

I have no power to my ob2 port and changed the fuses what else should I do.

Replace the 10amp fuse in fuse panel on the driver's side of the dash. The cover was hard to open as it doesn't pull out. It works like a door that you would open. The cigar lighter still doesn't work but it might have a wire loose or broken. This one little fuse fixed my radio, dome and overhead console lights, OBD plug and the remote controlled mirrors.
