Diagnosis Ford Focus TDCI purchased in 2003

Hello, I'm new to the forum and I'd like to know if anyone has managed to read the fault codes on a 2003 Ford Focus TDCi
and what equipment they used. This vehicle has an OBD connector but doesn't meet all the requirements of this protocol, as it wasn't mandatory for diesel vehicles until 2004. I've read in some forums that the ELM327 interface isn't compatible with this vehicle either. I would appreciate any help on this.
P.S. I have the original workshop manuals from the manufacturer for this model but I don't know how to upload them. Could someone explain how? Thanks.

Hello, I have entered with the Axone without any problem, but I do not remember if I have needed an obd adapter. If it has 2000 cc or the 1600 of Citroen test entering as a C4 for example.
