The brute force way of accomplishing this goal would be to build a can sniffer and do some packet analysis. I have a software sniffer on my PC somewhere that was given to me a long time ago which records the data like wireshark. You would then try and replay those back back until you managed to trigger the alert you wanted.
If you want actual customized messages you may need to modify the cic firmware as I doubt strings are sent via Can. Then the associated hardware to trigger the arduino and then the bulk and reliability and ease of use come into consideration when you're past prototype. At that time you'll start contemplating plastic injection and you may as well start at business making Legos and army men.
The other way to go about this is to check your methanol tank routinely.
