I have a 2000 ford f250 super duty with the 6.8l v10, and its 4x4. my service engine light abs light came on and my overdrive off light started flashing while repeatedly chiming in and out every 2-3 minutes. I have a hypertech power programer and read the codes but all it came up with were 2 codes, p1000 which is an invalid code because it means obd2 has not finished analysys. and a p7a00. I can't find this code anywhere,and actually i found a forom stating it doesn't exsist or its a programer code. Help?
funny thing is there are no issues with the engine or trans, but the speedo will jump around 5-10 mph. runs fine, shifts fine, everything works exept overdrive button cause its flashing. very weird.funny thing is there are no issues with the engine or trans, but the speedo will jump around 5-10 mph. runs fine, shifts fine, everything works exept overdrive button cause its flashing. very weird.

I"m as puzzled as you.Try getting the truck plugged into an actual
Ford Diagnostic Scanner, rather than your aftermerket programmer,is all I can guess to help your situation. Good luck.I"m as puzzled as you.Try getting the truck plugged into an actual

Had the same exact issues with my 2000 Diesel. Windshield seal was no good, water was getting to electronics. I replaced the windshield and all the problems stopped.
There will be a wire leading to the abs sensor on the inside of the wheel (dual wire actually usually green and black). So you should see the brake line and a wire. If no wire, no front abs.
It sound is if your ABS/Speed sensor is the culpret. Try this fairly inexpensive repair before you bring it in for a Diagnostic, which can run anywhere from $89.95 & up. Go to the local ford dealer in your area and ask them for the ABS Sensor in your rear axle differential. The base part number being 9E731. This part runs roughly for about $20.00+ and your own time to replace it.
Check you speed sensor on the transmission, Overdrive wont work without speed sensor, nor will ABS, or Speedometer.. it all boils down to a speed sensor.
abs light on as well? even tho you changed the speed sensor did you clean the contacts really well? i had the same problem i replaced the sensor and nothing.... then found out the contacts were corroded took the sensor back off and cleaned the contacts. works like a charm! try that and let us know if that helps.
I'm a Ford service adviser. There are many reasons for the
abs warning indicator to come on. The usual cause is from a
faulty speed sensor. Either a wheel speed sensor or the
differential speed sensor. I don't think the light is related to your
vandalism. You might want to take the truck to an auto parts store and
have them read the codes for you. Most auto parts stores will do this
for free.
Good Luck
Your speed sensor in your trans. needs to be checked out sounds like its not working or not getting a good signal until its generating enough power and speed to start until it reaches 30 MPH. Check that out sometimes it could just be some dirt on it. It all makes sense the ABS light is on because its not reading the speed of the tires, and the AOD light is on because It has no idea when to shift into overdrive without knowing how fast its going. I sure Hope that Helps You Out, And Thanks, Bear001
