DigBox Lexia3 - no dialogue with ECU Problem

[saeedm]

hi there.
i have Xantia x2 with xu10jr-rfv engine and Bosch mp5.2 ECU. there is no CPH.
i bought DigBox lexia3/pp2000 and installed on win7 32bit. updated to 7.57v
the lexia 3 can show ABS and AirBag faults and test them
but cant connect to ECU for engine diagnose test. this is the erorr (picture1):
the problem is from ECU or DiagBox ?

You might find this thread helpful, as there may be issues communicating with older vehicles on all ECUs, which often used the earlier Proxia or ELIT systems:
