Hello and welcome to justanswer.com
When the fault light comes on there may be a problem with the motor or parking brake module. You will need a Ford scan tool to read the fault codes. What you can do is disconnect the negative battery terminal for 10 minutes. Then reconnect it, start the engine and pump the brake pedal. Then while you hold your fot on the brake pedal pull up on the parking brake switch handle. This will reset the parking brake and may rectify the problem.
You will need a Ford scan tool to read the codes from the electronic parking brake module. Your scanner can only read codes from the PCM. The parking brake module is located behind the trunk liner on the driver side and the motor is located above the rear differential underneath the vehicle.
