I repaired a PS3 BC today with the YLOD and the Syscon error log was showing 2113/2203/2022.
Worked out it was IC5001 near the HDD port.
The online error log shows these are related to the SB and the DVE error(IC2406) but ney,it was the IC5001 🤣 which should be a 2010 error going by the SCE Confidential Syscon error chart 🤷🏻‍♂️
I’ve had a couple of these in the last 6 months.
