Setting Up Your Hybrid

Recommended Posts

And, at least for Energi & Electric models the dominant fob is number 2. When both fobs are in the car the car must decide which is dominant for starting and adjusting seats.

When you touch the door handle the car sends out a low frequency signal.

The FOB responds with a VHF signal giving its serial number.

The car checks its stored list of fobs and if there is a match the car is unlocked. The position of the serial number in the car's table determines what the key fob number is. The car can have a maximum of 4 IA fobs.

 

Okay, Murphy, fess up. Are you a Ford engineer and do you perhaps share an office with Waldo? ;)

No but I did work for Philco-Ford back in the 60s when Ford bought Philco. In 1969 they shut down Philco-Ford and I was out of a job.

 

I know how the IA Fob works because I took the FCC registration number, that is inside of the fob, and looked it up on the FCC website.
