Hi all.
I bought this mark 8 a few months ago in the UK and have been slowly restoring it.
80K miles and a few minor niggles but nothing serious. Its had a replacement warranty engine at some point in its life.
I've managed to source a Ford factory scan tool - the NGK Star tester 2 with the correct modules to read every module on the car and even code keys in!!
Its proven a fantastic ride so far with no exra problems. Very comfortable indeed. Love it.
Anyway, back to one of the cars problems. The parking brake won't release automatically. I have to release it by the emergency lever at the side of the seat.
So, plug in the NGK star 2 tester and have a look.
What a surprise. Picking up C1446 - parking brake circuit fault-but I knew that already.
The SCIL module needs to know when the parking brake is on - which it confirmed it did, via the PRK BK signal at the module on the start tester.
It also needs to know when the foot brake is on and off, using the Brake On Off (BOO) switch at the top of the pedal. So into the PIDs on the tester and this is what it showed no matter what the pedal was doing
So I need to head off over to the SCIL module itself at the other side of the dash.
Here it is
And unbolted and swung down
What is that I see-the light green from the BOO switch has been cut! Wheres the other side?
here
So the question is - why was it cut? Just as i was about to find out my battery died!! serves me right for having the stereo on for hours while i worked on the car! So that is charging as we speak.
In the meantime, logically thinking, it must have been cut for a reason. Probably causing fault codes.
Now when american cars come into the UK, they have whats called an SVA (single vehicle approval) test, where things are changed. Like the lights. They must flash yellow at the back, so they are rewired with yellow bulbs in the back up light sockets for the turn signals. On my mark, a wire has been spliced into the output side of the BOO switch on the pedal and straight to the stop light bulbs. This provides a direct hot feed to the stop lamps. The original wire to the stop light has been cut and spliced into the yellow bulb for the turns.............and ha! that now explains why it was cut!
If the wire is reconnected the SCIL will know the brake pedal is being pressed and will try to light the stop light bulbs. But they are wired to the turn lamps, so...problems.
I want to get the parking brake operation back, so I need to fool the SCIL into thinking it is working normally at the rear (american style, but still stop lights red and turns yellow. Hmmm.........
