The P0573 codes is set when the stop light switch signal is too high.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Stop light inoperative
- Cruise control system inoperative
P0573 Description
When the brake pedal is depressed, the stop light switch sends a signal to the Engine Control Module (ECM). When the ECM receives this signal, it cancels the cruise control.

The brake switch will stop all current to the brake lights. As soon as the brake pedal moves just off of its fully up position, the switch makes contact and passes current on to the brake lights. You can operate it by hand to check if everything is right. izzit adjustable? The switch is the last thing in the path to the brake bulbs, so it has to work right, right off the brake pedal!

Move into a position where you can easily see underneath the driver's side of the Ford pickup's dashboard. How you do this depends on your physical size and dexterity.

Did you adjust the brake light switch correctly? To adjust the brake light switch, first press the brake pedal down a few inches, then pull the switch plunger rod out of the switch toward the brake pedal arm, as far as you can without using excessive force. Next, return the brake pedal to the pedal stop position against the pedal stop and pull the brake pedal toward the rear to push the brake light switch actuating plunger rod into the switch housing limited by the travel of the brake pedal arm rear travel stop position. This procedure automatically adjusts the brake light switch correctly.
If the brake lights still don't turn off with the brake pedal released, check the brake pedal arm for sticking or binding that is preventing the brake pedal arm from returning fully to the pedal stop when the brake is released.

Hello Mr Mixer.

When this happens it is usually a bad brake light switch mounted on the brake pedal lever.

2. Disconnect electrical connector for stop light switch.
3. Remove bolt and lock nuts attaching brake pedal to stop light switch and push rod.
4. Remove stop light switch and bushings from brake pedal.
5. Reverse procedure to install.

There you are.
I hope your repair goes well.

If brake lights not working then its quite possible that the problem is .either the brake light fuse or the brake light switch.The brake light switch is causing the turn signal light to stop functioning.Check out both the brake light fuse and the brake light switch. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Does the 3rd brake lamp illuminate? If so then your problem is multifunction switch.If it doesn't do the following checks.
Check for power to and thru the brake lamp switch itself.If you do not have power to the switch check fuse no. 10(20 amp) in the interior fuse panel.If you have power to the switch then depress brake pedal and make sure you have power thru the switch.If this is ok the check Fuse 22(20amp) with brake applied..

Most tail light problems are a result of a bad ground......somewhere.
