Having problems with your Ford Mustang ?
My 1998 Mustang won't start and the theft light flashes when the key is turned to run. The repair man told me the security system is the problem. The P.A.T.S. code is B1681 Tranceiver Module signal not received. How do I fix this problem?
The ONLY way to reset this particular system from Ford, is to tow it to the dealer and they hook it to their laptop and it takes about 15 minutes to reprogram. Be sure to take all the keys you have or the program will render the other keys useless. There is no bypass or trick to getting this to work. It must go through their system. I wish there was a bypass to tell you about. It runs less than $100.
