T6 crank no start P3053 Starter Control

[divjakp]

Hi to all!
I have one t6 2.0 2016 engine stoped under driving and after that crank but won't start. First i saved vcds log with faults, cleared and only fault come back is P3053 Starter Control - 50 Short to Ground.
If someone wants to check vcds log, maybe had a same problem.

Please make a log of the following.

Ignition ON

VCDS > Select > 01-Engine > Adv. Meas. Values

Tick data items

IDE00021 Engine speed​

IDE00182 Camshaft adaptation intake bank 1: phase position​

IDE00347 Air mass: actual value:​

IDE00352 Main injection: duration of activation​

IDE00407 Rail pressure regulation: status​

IDE00412 Starter control: terminal 50​

IDE00416 Starter control: terminal 50 feedback​

IDE07744 Particle filter: air pressure sensor 1 bank 1: raw value​

IDE07818 Fuel high pressure sensor: actual value​

IDE07824 Tank-internal presupply pump 1 bank 1: activation​

Tick

verify the data is still alive


Log > filename > Start (the logging - IMPORTANT!!!)

Crank the engine (3 seconds is sufficient)

Stop (the logging), etc.

---

The result files are saved into directory C:\Ross-Tech\VCDS\Logs
Please post the log file

Thanks.
The fuel pressure build-up is normal and thus ECU commands injectors to fire (injection duration values are alive) (GREEN below).

engine stoped under driving

Obviously something disastrous happened at the moment. I would start by checking fuel at the HPFP high-pressure fuel pump for any impurities, e.g. metal shavings (which might have blocked injectors).

PS. The logging can be greatly enhanced by ticking "Group UDS requests" option as now we got only four measurements spaced 1.3 seconds instead of 0.2 second spacing to better capture any glitches in-between.


Below an example of the difference in sampling rate - for the same 5 second recording
