I'm getting a U0121 Lost Communication With Anti-Lock Brake System (ABS) Control Module 'A'

On both the PSCM and IPC

Where do I start - anyone else had this 

Thanks

What are you using to read the DTC's and get that code ?

Forscan

What happens if you try and clear the DTC ?

Just checking that we are talking about the Fiesta 2016

They return straight away and yes the 2016 ecoboost st-line

Checked the obvious fuses, reset the module, and even swapped out the module with another one all with still the codes remaining.

Have you checked the resistance of the canbus at the OBDII port ?

It should be 60 ohms if the circuit is complete

This video might give some help with fault finding.
