Hello, when you turn your key to the on position does the theft light flash fast?

Customer: replied 1 year ago.
the one in the dash does.
Expert:  James replied 1 year ago.

If you leave the key on for 1 minute it should begin to flash a two digit code. Ford example 14 can you do this and see what code flashes

If you can update me after the flashing of the code it will help. The other thing I would try if you have your owners manual is swap out the pcm power relay with a different relay and see if it helps.

Expert:  James replied 1 year ago.

Those are the only couple of things you can do without some special tools or equipment. Its most common for a pcm power relay failing but the ring around that reads the key code can also be bad.

Where do I read the code from

Does the security light blink a code? I don't know what I'm looking for
Customer: replied 1 year ago.
Its not flashing a code only thing I see is the normal message center stuff life how many miles to empty and mileage things like that

Where is the pcm power relay located?
Expert:  James replied 1 year ago.

The theft light itself will blink out a code. The PCM relay is relay number 3 under the hood. The fuse panel should have the numbers labeled.
