hi all i have a N reg scorp 2.0 ulitma . Was working fine then it rained and now it wont start. Followed some of the posts about water probs with pats . But if i take the ccm out the light stay the same (the red one on the top of the dash)and it makes no diff . So can i just change the ccm or is there more to it (reprogramming keys ect..)

The CCM is not connected to the PATS as far as I am aware,the engine will run whether or not the CCM is in situ.The PATS is operated via the chip in the key,not by locking the doors.

Cars with EEC IV PCMs all had a seperate PATS unit which is not easily accessible and is mounted to the right of and lower down than the CCM and PCM.I am given to understand that cars,and certainly later cars with EEC V as yours has,have the PATS system IN the PCM.There is a possibility that if you have water ingress it may have entered the PCM which is underneath the CCM,and is usually rivetted into a cage,these rivets must be drilled out to remove the PCM.

If indeed you find water inside when you remove covers,not to say that you will, I would think there is a sporting chance of drying it with a haidryer.It only has one multiplug held by a 10mm bolt and is simple to swap once you have drilled out the rivets.You may be able to borrow one from someone on here to try.
Just noticed you say yours is a 2lt,then it's a Cossie ! or have you put a Cossie PCM into a 2lt,if so there may well be differences ?

Has the engine got a black plastic cover over a pair of big aluminium intake manifolds shaped to fit over them,and does it bear inscriptions 24v and Cosworth,if so that's what it is.You would appear to have a mystery bitsa,and I think you should consult the HIGHLANDER oracle for further info.Send him a PM with your vehicle details and ask him if he could spare the time to advise you further.

I looked at a Cossie unit,it is one digit different from yours,95GB 12A 650 HD.
12v units are very different,starting 90GB,an older system!

Just had a read over this post, you seem unsure which engine is actually in it, one post you say it says Cosworth on the engine cover then you say its a 2 litre??
Can you post a picture??
I'm just thinking there may be an outside chance you have a YABB Cosworth engine out of a Sierra/Escort which someone may have fitted previously??
What are the actual symptoms then?
what does the PATS light do?
If it were a PATS problem the engine wouldnt turn over.
Are you getting a spark and fuel??
Fuel cut off switch in the boot and a dud battery would be my first guesses

its a dohc 12v 2.0 litre going by the owners hand book pics but it has powered by cosworth writen on the top . The fuel cut off in the boot is ok and the bat is charging ok on me bat charger and it starts me camper van ok and turns the scorpio over fast. The pats light comes on when you put the ignition on for about a sec then goes off and does nothing more . The fuel pump comes on for about three sec then goes off when it is on you get 12 volts down to it then nothing . The blead value by the injectors when pressed fuel comes out so would say fuel is getting down but how much not sure . When you turn the engine over it goes to fire up but thats it but carrys on turning over hope this helps you
I have two black keys with red bits and the red key no of them make any diff to it
Have emailed pics to you highlander as could get them posted up on here
