[QUOTE="FordTechOne, post: 1712170, member: 35543"] It sounds like your high mount/3rd brake light is internally shorted. When the parking lamps/headlamps are on, voltage from the running lamps in the high mount brake light can short to the brake light circuit. That backfeeds into the BCM, which then sees that the brake lights have voltage when the shouldn’t. This information doesn’t match the brake pedal position switch, so DTCs are set. To check the 3rd brake light, measure continuity (resistance) using an ohm meter between pins 3 and 5. If there is continuity between those two pins, the lamp is shorted internally. [/QUOTE]
