2017 Acura MDX 3.5l SH-AWD No Reverse, Multiple Dash Lights, No Communication With Scan Tool

HI, I got called out to a 2017 Acura MDX 3.5l SH-AWD with the complaint of no reverse, multiple dash lights on, and they could not communicate with the vehicle using their scan tools. I manually ID the vehicle and was able to communicate with some of the modules on the vehicle. Some of the ones I could not communicate with were the ABS, PCM, SRS, VSA, and TCM. I went straight for the network lines.
