Hi, I am a new member from africa and a mechanic. I fix ford vehicles and I really hope to enjoy these forums and also contribute my best .

I have a 1999 mountaineer that has refused to start after having been driven to the place without problems. On diagnosing I get the informations below.

SCP is missing

Key communication with pcm codes...

Please I would like to know what to do about the scp message.

I bought pats2 keys and tried programming the keys but always got the SCP message. Any suggestions please.????

Welcome!

BTW: Besides other issues, if you have the 2nd generation transponder key, you have to have 2 original keys in order to program any other (a third one). 4 is the maximum.

If you have only 1 key left, you have to have the dealer program it.

Greetings!
