ID...tells you what’s wrong. ie: oil pressure, water temp etc. Sorry but I do not know what the 639 code pertains to.
FM...stands for failure mode. 12 means a device or component is not working properly. So likely it’s a sensor that needs replaced.
CNT ....stands for count. Number of times it’s failed.
Hopefully someone with a C7 will be able to tell you what the 639 code is.
Or you can call Linear Logic at 1--888-433-5664.
