LR3 2008 (Disco 3): Vehicle System Shutting Down on radio. Suspension is lowering. Multiple dash fault lights but not always the same codes. Multiple fault codes on Autel MaxiAP200/Diag-Europe. Flashers on. Radio and on Screen Supension Monitoring screen goes dark. A/C fan goes on and off. When I clear the codes the system seems to reset and it will start and drive normally with no flashing fault lights on the dash. Everything seems to be fine - but then it happens Vehicle System - Shutting Down will come on and the process starts over. I have changed the brake light switch and willing to swamp out the ignition switch. I was thinking instrument cluster or battery cable corrosion? I want to pull the instrument cluster out and see if the connection is loose or if there are any bad solder points. I may have disconnected the hand brake (parking brake) or it's stuck. Could my PCM or ECU be shot? Seems like my code report from my Autel Dongle is always a little different. Sometimes there are more than 10 fault codes. Should I start with the instrument cluster?

Start with battery voltage, is it charging off the alternator, check battery terminals and earth points all over car

Sounds like a low voltage issue, so definitely do as suggested above. It's unlikely to be the engine ECM, especially if codes are across various systems. There are about 30 control modules in this vehicle, so faults across several are unlikely, unless there's data corruption caused by wiring issues or low voltages.
Battery condition and alternator output are definitely the first things to check.
