Fault Codes for Both Rear Door Control Modules

I ran a VCDS scan today to troubleshoot another issue, and I noticed some fault codes related to both of my rear doors. I Googled for a while, but what's odd is most of the threads with similar codes are from people having issues with their rear doors. I am not experiencing any issues with my rear doors. My windows and and my door locks work fine. These are the faults:

01333 - Door Control Module; Rear Left (J388)
49-10 - No Communications - Intermittent

01334 - Door Control Module; Rear Right (J389)
49-10 - No Communications - Intermittent

Thoughts? I cleared them but they returned during the next scan.

It's saying Intermittent
Could be a problem in the wires going through the boot in the door jam. Frayed or broken.

Don't know if one of the 3 micro-switches in the door could be hanging intermittently and being picked up.
