ABS diagnostics communication

[323coupe]

Please help,
The ABS and ASC lights are permantly light up when the engine is running. My mechanic's fault finding diagnostics computer cannot communicate with the ABS system to determine the fault. I've read the lights could be on because of the wheel sensors but that would not solve the communication error as the system needs to be reset after the sensors are fixed anyway.

Need to get this fixed for the MOT, does anyone have any ideas?!

I HAVE THE SAME ISSUE, error communicating with the module. i ignored it and never had any problems other than there is no traction control
