The air pressure is good (brakes do not engage). After update 6, whenever I put on the Parking Brake the master caution alarm comes on like normal but if I hit the Master caution button to silence the alarm the button goes from bright red to no red as it should. The problem is that the Parking Brake Alarm still keeps beeping. The only way to silence it now is to turn the parking break off. If the parking brake light doesn't turn off, several troubleshooting steps can be taken to identify the issue. These include-1. Checking The Parking Brake Switch . The parking brake switch is under the parking brake lever or pedal. Ensure the parking brake lever or pedal is fully released to check the button. Apply the parking brake, then remove the floor console rear finish panel. Apply the parking brake. Remove the floor console finish panel. Remove the adjustment nut clip. Turn the parking brake control adjustment nut so that the parking brake control stroke is three to five notches when pulled. .
