how to fix brake codes on Ford F-150 14th Generation (2021-2024)

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, jack and jack stands, multimeter, brake fluid.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Fault Codes

1. Clear Existing Codes:

   • Use the OBD-II scanner to clear the trouble codes after noting them.
   • This helps in identifying if the codes return after repairs.

2. Inspect and Replace Components:

   • If specific codes indicate faulty components (e.g., ABS sensor, brake pads):
     • Remove the wheel using the socket set.
     • Inspect the brake pads for wear; replace if below 3mm thickness.
     • Check the brake rotors for scoring; replace if necessary.

3. Brake Fluid Replacement

1. Flush Old Brake Fluid:
   • Locate the brake fluid reservoir, remove the cap, and suck out old fluid using a turkey baster.
   • Fill with new brake fluid as per manufacturer specifications (DOT 3 or DOT 4).
2. Bleed the Brake System:
   • Start with the wheel furthest from the master cylinder. Open the bleeder valve while someone gently presses the brake pedal.
   • Close the valve before releasing the pedal. Repeat until clear fluid flows without bubbles.

4. Electrical Connections

1. Inspect Wiring and Sensors:
   • Check the wiring harness for frayed wires or loose connections.
   • Use a multimeter to test voltage and continuity at the brake sensors.
   • Repair or replace damaged wiring as necessary.

5. Reassemble and Test

• Reinstall the wheel and lower the vehicle from the jack stands.
• Reconnect the negative battery terminal and perform a road test to verify the brakes function correctly.
