I have a 2014 Mazda 3 Sport Nav 2184cc diesel BL. The tyre

Hi, I have a 2014 Mazda 3 Sport Nav 2184cc diesel BL. The tyre pressure, traction control andcity anti colision lights came on and cannot be reset. My Mazda dealer said I needed a new ABS unit asthte ECU in it was faulty. I had the ABS unit checked out by an ECU repair company who found no fault. The problem still exist. My local non- Mazda repair agarge says eh thinks the power steering ECU is not gettin data from the ABS and is the only fault he can see with his CANbus monitor. Is there a link?
