2004 FORD F SUPER DUTY Electrical System Problems

AS I'M DRIVING, THE HORN WILL SOMETIMES JUST START BLOWING BY ITSELF FOR NO REASON. THIS IS AN EXTREMELY UNSAFE AS WHEN I'M DRIVING AND THIS HAPPENS, IT'S WILL SCARE ME COMPLETELY AND USUALLY THOSE AROUND ME. I HAVE TO QUICKLY PULL OVER AND BANG ON THE HORN TO GET IT TO QUIT BLOWING. IT SEEMS TO BE IN THE AIRBAG AREA. THANK YOU.

THE TRUCK STALLED WHEN I WAS GOING 70 MPG ON THE INTERSTATE IN TRAFFIC AND WOULD NOT RESTART UNTIL IT SAT FOR 3 MINUTES. *TR

DRIVING TRUCK DOWN ROAD I HEAR THE RADIO SHUT OFF, THEN ALL DASH BOARD LIGHTS ARE OFF. LOOK AT THE DASH BOARD GAUGES AND THEY ARE GOING NUTS FUEL , BATTERY , TEMP GAUGES, AND SPEED O WOULD PIN BELOW 0 THE TACH GAUGES WOULD PIN AS HIGH AS IT WOULD GO THEN START MOVING UP AND DOWN FAST. . LAST A FEW MINS THEN GO BACK O NORMAL. I PULLED THE TRUCK IN THE DRIVEWAY IT STARTED ALL OVER AGAIN AND THIS TIME IT WAS DARK OUT AND ALL THE OUT SIDE LIGHT WERE OFF WITH EVERYTHING ABOVE AND THE WINDOWS WOULD NOT GO DOWN OR NOW IF THEY ARE DOWN THE WOULDNT GO UP. *TR

WHILE TOWING A 13000 POUND FIFTH WHEEL TRAILER WITH MY TRUCK (2004 F250 6.0L DIESEL ENGINE) THE ENGINE SHUT OFF. I LOST POWER STEERING AND POWER BRAKES AS A RESULT. I WAS ABLE TO SLOW DOWN AND PULL OVER TO SHOULDER LANE. AFTER COLLECTING MY BREATH I TRIED TO RESTART THE VEHICLE. IT STARTED, BUT THE ENGINE LIGHT CAME ON. THE ENGINE RAN VERY ERRATIC,RPM VARIED WHILE SITTING AND AS I ATTEMPTED TO DRIVE IT. I STOPPED AGAIN. STARTED AGAIN AND NURSED IT HOME. CHECKED THE CODE READER WHEN I GOT HOME AND FOUND THE CODE TO BE P2285, INJECTION CONTROL PRESSURE SENSOR LOW VOLTAGE. *TR
