2004 CEL Question

I have a scan tool that has a "flat plug" that I used to used for my 1999 Honda Accord (OBD2)

My 2004 LS V8 blew a cluster fuse last night (5amp number 13) and then when i replaced the fuse my Lincoln had its CEL light came on?

I looked for a hookup but the only one i could find was under the hood on the driver side strut tower and it was the wrong size (more of a rounded plug). I looked in the manual for a diagnostic port but no go.

Is there a way I can pull the code and reset it? I was trying to hardwire my radar detector and thought the cluster would be a good one... i guess not.

Thanks

All 1996 and newer cars sold in the US use the OBD2 system, and by the standards, the diagnostic connector must be located within 2 feet of the steering column. You will find the connector on your 2004 LS at the bottom of the instrument cluster. My recall it that it is located at the base of the knee trim panel towards the center console. I no longer have my 2004 LS8, so I can't go look. However, I know it's in that area.

Your 2004 LS uses the Controller Area Network (CAN) protocol though, so your scan tool will need to be CAN-compatible.

I suspect the code you have will be related to low Keep Alive Memory (KAM) voltage due to the blown fuse.

What is the rating of the fuse that came with the radar detector? Did the fuse blow because it overloaded the 5-amp circuit, or because of a wiring fault?
