Any help with this code?

Error Code P0573
Definition Brake Switch No. 1 Stuck High/Off
Possible Causes:
BS No. 2 signal open or shorted to ground BS No. 1 signal shorted to ground or to voltage Ground circuit is open Fused ignition switch output is open Stop lamp switch is damaged or has failed PCM has failed

Condition For Setting The Code:
Ignition is on. If PCM recognizes BS No. 11 is mechanically stuck in the high/off position, this DTC will set

The jeeo (05 sport) eats brakes right now.
AS well as no speedo or odom. I have had the jeep to 2 dealers but with no luck. I drive for a living so most of the time I do the repairs over a weekend.
any info on what/were bs no.11 is.
thanks for any help

Does your brake lights work? If not replace the brake switch attached to the brake pedal,should be fairly cheap and easy to replace.Recommend OEM replacement part,stay away from aftermarket junk.

Being as the speedo does not work also better be checking the wiring to the speed sensor on the rear diff and/or the sensor itself.Again OEM parts only,if the wiring is bad a pigtail can be had from the dealership also and is the most common issue for no speedo.No speedo should also throw the OBDII code P0500.

When I tried a search on P0573 on this forum:http://www.jeepkj.com/forum/showthread.php?t=44871&highlight=P0573

internet TSB from June 10 2005 for 05's came up. http://www.carcomplaints.com/Jeep/Liberty/2005/tsbs.shtml
TSB #0802905 NHTSA ID #10015800
looks like some reprogramming took place...

There was discussion here too..http://www.jeepforum.com/forum/f28/vehicle-malfunction-light-242237/
But TSB seems to relate to to 4x4 light coming on...
With the speedo out and odometer, sure makes me feel like a ground wire or something is not right from the BCM or wiring into the Cluster. Was any mods done for alarm or stereo etc around the dash?

Thanks, The brake lights work. its more like a stuck brake, but so far I have not found out what it is. I had the dealer Reprogram the Powertrain Control Module (PCM) but it did nothing.
I have a nav unit in the dash the picks up the speed through the pcm (a wire runs out to it from the stero) So i would think its not in the wire up to that point
again thanks for any help
