Loss of Communication Codes
I have the following codes coming up. Any ideas of what could be causing them and how to fix it? Thanks!
U1016 Loss of Communications with PCM
U1096 Loss of Communications with IPC
U1064 Loss of Communications with BCM
I cleared old codes about 2 weeks ago and so I know these codes are recent.

The codes are pretty normal. It happens very frequently and can be ignored if you are not having any other issues. If you clear them, they will return eventrually. If you did have a real problem, they may return immediately which could indicate that the loss of communication is part of the problem.
They occur because the communication between the different systems in the car share a single communication line (data bus), and some times its busy when a system wants to use it. When that happens a code can be set. The line can be busy because another system is using the line. Completely normal.
Bottom line, don't worry about it.
