Com 2003 citroen repair

[PSAcars]

Hello to all. This is my car com 2003 Citroen C5 II, it is giving error for steering angle sensor(internal error steering angle sensor), in live data in diagbox it's shows not operating. I open the com and took down from pcb all optodiodes and optptransistors (TEKS5400 , TSKS5400), all working tested. I took down all hall effect sensors 5pc, all working ok. There is 5v on the ic's. The Motorola 4L52H is for the ISP (steering angle sensor) the NEC is for wipers, turn signals, radio, cruise control, trip computer....... .The brown connector is for the key antenna, blue connector is for isp, grey connector is for the bsi. I think is a software problem, in the motorola mcu. If someone have info about that problem, please write on. I have upa usb, in upa there is 4l52h but here on dk many say that it is not possible to read.
