V70 OBD2 works but can't see other modules
2004 V70 that I'm trying to help a friend out with. I'm using a Vident scanner that is supposed to communicate with all the modules but I get a communication failure no matter what module I try to read.
The problem with the vehicle is no crank. It shows a "severe" air bad problem on the dash. The transmission indicator shows the proper shifter position. If I jump the starter relay it cranks but doesn't start.
I'm thinking that there is something wrong with the computer system since I can't communicate with any of the modules.
Help!

Got the CEM and ECM back and things are different but still not right.
At first it would crank with both keys but only start with one. After switching keys back and forth about 10 times it would start with both keys. ???
All but 2 modules showed trouble codes so I cleared all of them and then a couple of minutes later the bus communication went down again.
I sent a message to Xemodex and waited a couple of days. Tried it again and communication was back up and only one code - no communication with AEM and then communication went down again.
Where is the AEM so I can disconnect it?

D5T5 has VDASH for free
I downloaded VDASH last night it appears to do everything VIDA does for free plus you can purchase and download tunes. I scanned my 2004 V-70 and changed my speed limiter to 160. I'm using a Chinese Dice clone and a Windows 10 Laptop.
