Hello. first time posting. UK spec cts 3.6. When starting the car it says "Service security system" I can ok the message and the car runs faultlessly. I think it started when a new battery was fitted. Is there some way of deleting or resetting this warning/fault code? The car has the nav system and it comes up with a picture of the bonnet/hood open. Any ideas? The nearest, only dealer is the other side of the country about 300 miles away. Thanks for any help.
