We just finished dyno tuning a 2017 Ecoboost Mustang and now are getting a "Steering Assist Fault Service Required" message on the driver display that will not seem to clear. It started coming up during the dyno pulls, but I just chalked it up to the ABS/Stability system faults and figured it would clear once we started driving it again, but it hasn't. Battery resets, also did not work.
Has anyone else experienced this when using HP or other software to tune these cars? The 2015 EB Mustang we just did 2 weeks ago was fine so this may be a bad case of perfect timing, but I wanted to reach out and see if there was something we were missing or a module reset procedure that needs to happen. Maybe it's a 2017 flashing issue?
Any insight would be appreciated.
