ford focus 4, 2024, as built problem
Posted: Tue Feb 10, 2026 11:18 am
i need yor help.
CAR BRAND NAME: Ford
MODEL: Focus 4 2024
PART NUMBER: PV4T-14B321-AB
CPU / EEPROM: R7F701064
Someone tried to erase the collision record from this control unit, but it didn't work. The control unit's software is probably corrupted. Then, someone else tried to erase the collision record from the existing problematic software without installing a completely clean software update, and that didn't work either.
I compared the as-built data of the airbag control unit (Forscan) with the data downloaded from Ford website. Lines 737-06-01, 737-07-01, and 737-09-01 have been added to the control unit. In other words, its structure is corrupted. It's possible to change the data, but I don't know how to remove the lines.
I checked the vehicle with a diagnostic device. Despite the vehicle not having a third row of seats, there are seatbelt dtcs related to the third row. There are also the following faults: (U2101:00-AF - Control module configuration incompatible, U2300:55-AF - Central configuration). on the bench errors at below.

U2100:00-AF - INITIAL CONFIGURATION NOT COMPLETE
U2300:55-AF - CENTRAL CONFIGURATION (Not Configured)
We installed srs ecu to the vehicle, then checked the SRS block status with Forscan. We saw that it was the same as before, it hadn't changed. There are more blocks than there should be as pictures. We tried to learn from the central configuration, but it didn't fix it. We also tried loading the as-built files from the factory data, but that didn't work either. Then the U2101 error reappeared. If you have any advice, I would be grateful. best regards
I couldn't upload the images because the system gave an error.
