Hello,
Issues started a couple months ago,
FOB started working sporadically replaced, relearned, then the new ones started doing the same thing.
Radio, gauges turn off while driving.
The security light comes on when everything stops working.
Does not start all the time. You have to pull the key out, put it back in, or sometimes just hold it to the crank position. So far eventually starts.
Truck never dies whilst driving..
Ran codes, none show.
Research on the Intraweb here I diagnosed it as faulty theft deterrent module.

So I have purchased a new theft deterrent module but from what I understand you need to reprogram it, not able to do it with the 30 min relearn.

Anyone run up against an issue like this?

Does anyone know how I can reprogram the theft deterrent module myself?

VIN# 7F504997



Thank you,
and have a great day!

 

probably requires dealer programming.

you probably will have theft codes but a code reader will not read body codes. a full function scan tool is needed.
