Toyota 8FGU25 fault codes

I am working on an LPG unit (which was running) that at first had two fault codes along with a check engine light, they were 03-1 and 05-2, related to intake pipe pressure sensor and throttle position sensor respectably. While troubleshooting them a third code appeared, Ad-1, and the unit now will not start. That seems to be related with the "CAN communication 4Y-ECS data reception". The low fuel alarm is also ring incessantly now, although there is ample fuel supply. Any ideas on where to look will be greatly appreciated. Thanks in advance!

Fact of the week
Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
