Renault megane 1.5 dci 2007 un known codes?

[Drift-art]

I'm using a solus pro on 11.4 software.

The car will not start, it turns over then says braking fault followed by injection fault.

It's a Renault megane 2007 mk2 1.5 dci delfi ecu.

I plug in solus and engine codes:
DF038- COMPUTER MALFUNCTION

and abs codes:
DF152- MULTIPLEX NETWORK ERROR

I can find out what these codes mean, I've googled with no success

Any advice would be appreciated

No Start

I would write down codes, try and clear them, after fully charging battery (nothing electrical works right with a low battery) Check if there is an immobilizer theft light is flashing ?See if Solus Pro can read engine data , If so , check graph signals of Crank and cam sensor. If theyre good , line up where they should 2-1 and consistent ,then start with basics. Oil, coolant levels and condition , Cracked Air intake vacuum hoses, Compression,no spark, no fuel, wrong fuel, fuses, grounds, , connections. Did car not start shortly after aftermarket radio installed ?
