When it comes to your Jeep Wrangler, the error code P0573 isn’t one you should ignore.

Deciphering The P0573

To begin, the P0573 error code is directly associated with the brake switch “A” circuit. This switch is a sensor that detects when the brake pedal is pressed, activating the brake lights.

This could result in your brake lights staying on or not working at all, posing a serious safety risk.
