[URGENT] Ford Transit Custom 2018.5 (BCM ) – IPMA keeps throwing U2100 after calibration. Need help resolving this

VIN: WF0YXXTTGYJJ81800
Trim level: Limited

I’m looking for assistance with an unresolved issue related to a retrofitted IPMA module in my 2018 Ford Transit Custom (BCM , April 2018).
The camera was retrofitted from a donor vehicle, the windshield is new, and the wiring harness was built according to the schematic.
The camera calibration completed successfully. After upgrading from SYNC 2.5 to SYNC 3, a previous IPC communication fault was also resolved.

However, one issue remains:

IPMA (KK2T-19H406-CC) consistently reports: U2100 – Initial Configuration Not Complete

Vehicle specifications:

  • Transit Custom 2018.5+ with BCM KK2T

  • VIN: WF0YXXTTGYJJ81800

  • Trim level: Limited

  • SYNC 3 sourced from a Custom

  • IPMA retrofitted from a donor

  • No electric power steering (no EPAS/PSCM)

  • Standard cruise control

  • Aftermarket/retrofitted CVBS reverse camera

  • Rain and light sensor

  • Planning to enable AHB (Auto High Beam)

  • No front radar (no ACC/AEB)

  • Front and rear PDC

  • ABS and ESP present

Symptom:

  • U2100 reappears immediately after clearing.

  • Camera calibration finished without errors.

  • The camera operates physically and all other modules on the network show no communication issues.

  • IPMA refuses to complete its initial setup procedure.

I need help determining:

  1. The correct IPMA AsBuilt values for a Transit Custom 2018.5 without EPAS, using camera KK2T-19H406-CC.

  2. Which parameters must be enabled in BCM and IPC (LDW, TSR, AHB, Camera Type, etc.) for the IPMA to finalize configuration.

  3. A working IPMA AsBuilt dump (lines 700–740) from a 2018.5+ Custom with the same camera.

  4. Whether U2100 on this model clears only after a full Vehicle Configuration download (FDRS/UCDS), or if manual AsBuilt editing is sufficient.

Any verified information would be greatly appreciated.
Thanks in advance.

First off, Do not put [URGENT] in your title like were all here to serve you.

If your adding an IPMA to get LKA than you need an EPAS steering assy. If you dont have that than there is no reason to add LKA as it is not going to work and you will get DTC’s like you have becuse you can’t calibrate something you dont have.

Won’t work.
