Judging by the rust stain on the case the first thing you need to do is fix the leak in that area.
Whilst not of any relevance to your problem if you didn’t press and release the brake correctly during the engine running test you will get a P1703 code.

Hi Dave,
Thank you for reply.
> You can remove CCM from car and it will still start
This fact surprises me.
I found two little black boxes beside EECV. Are they PATS?
There are two thin earth lines connected on battery. Do you know where are they go? I think two thick earth lines
connect to starter and generator.

Hi Tompion,
Thank you.
I had fixed my leak and I will keep observing this problem.
Months ago, mechanic used wood flour, plastic board and glue to rebuild the battery room (since battery room have been corroded and water flowed inside car from hole).
So, the rust stain on the case you saw is wood flour.
And you are right on P1703 code. I try engine running test again with correctly pressing and releasing the brake.
There is no any code on "Forscan" now.

PATS says PATS on it lol 
Not sure where them earths go, it's been a while
I expect one of them goes to BJB and other one to body.
They will be shown on the wiring diagrams in TIS or on this site
Cheers Dave

BJB is Battery Junction Box (the oblong fuse and relay box under the bonnet).
TIS is Technical Information System (can be purchased on disc fromEBay).
TIS contains all sorts of useful stuff including wiring diagrams and workshop manuals.

Hi Dave,
Thank you for reply.
I pull the little black box (in fact, a terminator) off, then there is the error code U1147 -- "There is a problem with the communications link between the PATS and the PCM. Use DMM to check the communications link wiring. " And the engine cannot start (but starter motor running). When I put the terminator back, engine can start again.

From 2 of my previous posts................

1:6 means faulty communication between PATS Module and ECU, probably dodgy connection, I'd be looking at possible water ingress into Fuse Boxes, and check PATS module plug and look for signs of water.
Pin 21 PATS goes to pin 16 ECU
Pin 22 PATS goes to pin 15 ECU
These 2 wires are the SCP Protocol com line, and also Tee off to other modules such as CCM etc so you can read codes and program

Your car parts are back to front, because it is a LHD, but that looks like it.
It should have a sticker with part number and says "PATS" on it, just so the car theif can find it

But it is difficult to remove the bracket (three nuts) shown in step 6 of the following PDF.
That is, I cannot find middle nut (numbered 2). Is it covered by a thick iron sheet?

And I think the car shown in the PDF is Right Hand Drive (RHD). If LHD it should be this one:

Hi,
Thank you for reply.
I release the screws numbered 1 and 3 but cannot find 2.
Does anyone have the pictures of standalone metal cradle? Thus, I can find the position of the screw numbered 2.
Thank you.

Hi,
I finally solve the problem. I use sandpaper to sanding all connectors of (-) end of battery. The black CuO was cleaned. Then, there is no starting problem anymore. I think one of (-) line from battery concern the problem. Maybe one (-) line direct connect from battery to PATS.
Now, Scorpio 2.3 starts easily every time.
Thank you for all replies.
