Mercedes w167 Ignition starter alternator issue

Hello everyone, please I need assistance. I’m working on a Mercedes-Benz W167 with an Integrated Starter Alternator issue. The car starts normally but shuts off after a few minutes.I’m getting DTC P062F00.Has anyone experienced this before or can point me in the right direction? Any help will be appreciated.

Assuming this isn’t a wrecked or abused/modified car - I would start at the battery. Google the code. Indicates a software issue but also notes can happen with a failing battery. I’d start with the simplest first. If nothing wrong there, then I think you’re in for a visit to a dealership for some software work.
