Hi,
My system is the Ford System 4 Security System in my 2000 Expi installed by the Dealer when new.
Sure there are different types in these cars but just thought I'd explain how to get a vehicle started with the version that is in my car.
Mine is still not setting to the normal mode and I have to use the Override to start it each time. I cut the wire to the 125dB siren the other day when we were trying to jump the car and the alarm system has not been the same since. Today I rewired in the siren and it's still not working correctly.
When I called the local Ford Service Dept the electrical specialist I spoke to denied Ford ever installed a system like this. Funny, I have a Ford User's Manual for this System 4, printed by Ford but it just tells the basics. The Ford Dealer did not give me much confidence in their expertise.
Obviously I have more work to do before I get this issue settled.
