Put a new maf sensor on it and took care of all the codes for some reason, communication codes are now gone along with other codes, must have a fail safe if maf goes bad. Strange

Quite often faulty components can corrupt signals and appear as U codes.

Hello everybody! I own a 2015 Mazda 6 2.2 diesel. I got engine check light and errors with SCBS, DSC (dinamic stability control) and TCS (traction control) warning light . I ve tested the car, and for the check engine light I have P0101 code (mass air flow sensor), and for the rest U0433, U0401. Did you have this problem and how did you fix it? Do you believe that by changing de MAF the other symptoms ( SCBS, DSCM ,TCS) will disapeare??
Thank you and sorry for my english.

​​​​​​Mine was the airflow sensor defective. It triggered the other codes.Changed air flow and problem solved.
