About a month and a half ago my 2000 Mustang kept stalling or hard to start with the theft light flashing. Now it just quit but it is also blowing my #34 fuse (instrument cluster, PAT transceiver module, CCRM, Ign coil, and Ign transformer capacitor) The codes I got back where:
B1600 PATS (Passive Anti-Theft System) ignition key transponder signal is not received
B1602 PATS received invalid format of key-code from ignition key transponder
B1681 PATS transceiver module signal is not received
B1232 Antenna not connected-defective transceiver
The only thing confusing me is the blowing of the fuse..
If anyone can give me any info it would be helpful, as I'm a retard when it comes to cars.. LOL.

Thanks in advance..

Hi Davie, welcome.
Something you might consider trying,
I haven't looked at a diagram for your vehicle yet, but since you know some of the things on that circuit , if you unplugged some of the components maybe you might be able to isolate the short. If that doesn't show anything might have to dig further. Can you do that?

 

Hi Hanky..
Yes, will do first thing in the am. If that's not the prob should I look into getting the key and/or transceiver replaced?

 

Keys can sometimes cause problems ,but not usually short circuits.
To just start replacing parts without trying to locate the cause of the fuse blowing is not the best path.

 

I have got the car running but now it is stalling while idling, it has no power, spitting sputtering, and the fuse thing, gone don't know what happened there, it just disappeared.
